NAME
fzf - a command-line fuzzy finder
SYNOPSIS
fzf [options]
DESCRIPTION
fzf is an interactive filter program for any kind of list.
It implements a "fuzzy" matching algorithm, so you can quickly type in patterns with omitted characters
and still get the results you want.
OPTIONS
NOTE
Most long options have the opposite version with --no- prefix.
SEARCH
-x, --extended
Extended-search mode. Enabled by default. You can disable it with +x or --no-extended.
-e, --exact
Enable exact-match
-i, --ignore-case
Case-insensitive match (default: smart-case match)
+i, --no-ignore-case
Case-sensitive match
--smart-case
Smart-case match (default). In this mode, the search is case-insensitive by default, but it
becomes case-sensitive if the query contains any uppercase letters.
--literal
Do not normalize latin script letters for matching.
--scheme=SCHEME
Choose scoring scheme tailored for different types of input.
default
Generic scoring scheme designed to work well with any type of input.
path
Additional bonus point is only given to the characters after path separator. You might
want to choose this scheme over default if you have many files with spaces in their paths.
This also sets --tiebreak=pathname,length, to prioritize matches occurring in the tail
element of a file path.
history
Scoring scheme well suited for command history or any input where chronological ordering is
important. No additional bonus points are given so that we give more weight to the
chronological ordering. This also sets --tiebreak=index.
fzf chooses path scheme when the input is a TTY device, where fzf would start its built-in walker
or run $FZF_DEFAULT_COMMAND, and there is no reload or transform action bound to start event.
Otherwise, it chooses default scheme.
--algo=TYPE
Fuzzy matching algorithm (default: v2)
v2 Optimal scoring algorithm (quality)
v1 Faster but not guaranteed to find the optimal result (performance)
-n, --nth=N[,..]
Comma-separated list of field index expressions for limiting search scope. See FIELD INDEX
EXPRESSION for the details. When you use this option with --with-nth, the field index expressions
are calculated against the transformed lines (unlike in --preview where fields are extracted from
the original lines) because fzf doesn't allow searching against the hidden fields.
--with-nth=N[,..] or TEMPLATE
Transform the presentation of each line using the field index expressions. For advanced
transformation, you can provide a template containing field index expressions in curly braces.
When you use a template, the trailing delimiter is stripped from each expression, giving you more
control over the output. {n} in template evaluates to the zero-based ordinal index of the line.
e.g.
# Single expression: drop the first field
echo foo bar baz | fzf --with-nth 2..
# Use template to rearrange fields
echo foo,bar,baz | fzf --delimiter , --with-nth '{n},{1},{3},{2},{1..2}'
--accept-nth=N[,..] or TEMPLATE
Define which fields to print on accept. The last delimiter is stripped from the output. For
advanced transformation, you can provide a template containing field index expressions in curly
braces. When you use a template, the trailing delimiter is stripped from each expression, giving
you more control over the output. {n} in template evaluates to the zero-based ordinal index of the
line.
e.g.
# Single expression
echo foo bar baz | fzf --accept-nth 2
# Template
echo foo bar baz | fzf --accept-nth 'Index: {n}, 1st: {1}, 2nd: {2}, 3rd: {3}'
+s, --no-sort
Do not sort the result
-d, --delimiter=STR
Field delimiter regex for --nth, --with-nth, and field index expressions (default: AWK-style)
--tail=NUM
Maximum number of items to keep in memory. This is useful when you want to browse an endless
stream of data (e.g. log stream) with fzf while limiting memory usage.
e.g.
# Interactive filtering of a log stream
tail -f *.log | fzf --tail 100000 --tac --no-sort --exact
--disabled
Do not perform search. With this option, fzf becomes a simple selector interface rather than a
"fuzzy finder". You can later enable the search using enable-search or toggle-search action.
--tiebreak=CRI[,..]
Comma-separated list of sort criteria to apply when the scores are tied.
length Prefers line with shorter length
chunk Prefers line with shorter matched chunk (delimited by whitespaces)
pathname Prefers line with matched substring in the file name of the path
begin Prefers line with matched substring closer to the beginning
end Prefers line with matched substring closer to the end
index Prefers line that appeared earlier in the input stream
- Each criterion should appear only once in the list
- index is only allowed at the end of the list
- index is implicitly appended to the list when not specified
- Default is length (or equivalently length,index)
- If end is found in the list, fzf will scan each line backwards
INPUT/OUTPUT
--read0
Read input delimited by ASCII NUL characters instead of newline characters
--print0
Print output delimited by ASCII NUL characters instead of newline characters
--ansi Enable processing of ANSI color codes
--sync Synchronous search for multi-staged filtering. If specified, fzf will launch the finder only after
the input stream is complete and the initial filtering and the associated actions (bound to any of
start, load, result, or focus) are complete.
e.g. # Avoid rendering both fzf instances at the same time
fzf --multi | fzf --sync
# fzf will not render intermediate states
(sleep 1; seq 1000000; sleep 1) |
fzf --sync --query 5 --listen --bind start:up,load:up,result:up,focus:change-header:Ready

DISPLAY MODE
--height=[~]HEIGHT[%]
Display fzf window below the cursor with the given height instead of using the full screen.
If a negative value is specified, the height is calculated as the terminal height minus the given
value.
fzf --height=-1
When prefixed with ~, fzf will automatically determine the height in the range according to the
input size.
# Will not take up 100% of the screen
seq 5 | fzf --height=~100%
Adaptive height has the following limitations:
* Cannot be used with top/bottom margin and padding given in percent size
* Negative value is not allowed
* It will not find the right size when there are multi-line items
--min-height=HEIGHT[+]
Minimum height when --height is given as a percentage. Add + to automatically increase the value
according to the other layout options so that the specified number of items are visible in the
list section (default: 10+). Ignored when --height is not specified or set as an absolute value.
--tmux[=[center|top|bottom|left|right][,SIZE[%]][,SIZE[%]][,border-native]]
Start fzf in a tmux popup (default center,50%). Requires tmux 3.3 or later. This option is ignored
if you are not running fzf inside tmux.
e.g.
# Popup in the center with 70% width and height
fzf --tmux 70%
# Popup on the left with 40% width and 100% height
fzf --tmux right,40%
# Popup on the bottom with 100% width and 30% height
fzf --tmux bottom,30%
# Popup on the top with 80% width and 40% height
fzf --tmux top,80%,40%
# Popup with a native tmux border in the center with 80% width and height
fzf --tmux center,80%,border-native
LAYOUT
--layout=LAYOUT
Choose the layout (default: default)
default Display from the bottom of the screen
reverse Display from the top of the screen
reverse-list Display from the top of the screen, prompt at the bottom
--reverse
A synonym for --layout=reverse
--margin=MARGIN
Comma-separated expression for margins around the finder.
TRBL Same margin for top, right, bottom, and left
TB,RL Vertical, horizontal margin
T,RL,B Top, horizontal, bottom margin
T,R,B,L Top, right, bottom, left margin
Each part can be given in absolute number or in percentage relative to the terminal size with %
suffix.
e.g.
fzf --margin 10%
fzf --margin 1,5%
--padding=PADDING
Comma-separated expression for padding inside the border. Padding is distinguishable from margin
only when --border option is used.
e.g.
fzf --margin 5% --padding 5% --border --preview 'cat {}' \
--color bg:#222222,preview-bg:#333333
TRBL Same padding for top, right, bottom, and left
TB,RL Vertical, horizontal padding
T,RL,B Top, horizontal, bottom padding
T,R,B,L Top, right, bottom, left padding
--border[=STYLE]
Draw border around the finder
rounded Border with rounded corners (default)
sharp Border with sharp corners
bold Border with bold lines
double Border with double lines
block Border using block elements; suitable when using different background colors
thinblock Border using legacy computing symbols; may not be displayed on some terminals
horizontal Horizontal lines above and below the finder
vertical Vertical lines on each side of the finder
top (up)
bottom (down)
left
right
none
If you use a terminal emulator where each box-drawing character takes 2 columns, try setting
--ambidouble. If the border is still not properly rendered, set --no-unicode.
--border-label[=LABEL]
Label to print on the horizontal border line. Should be used with one of the following --border
options.
* rounded
* sharp
* bold
* double
* horizontal
* top (up)
* bottom (down)
e.g.
# ANSI color codes are supported
# (with https://github.com/busyloop/lolcat)
label=$(curl -s http://metaphorpsum.com/sentences/1 | lolcat -f)
# Border label at the center
fzf --height=10 --border --border-label="╢ $label ╟" --color=label:italic:black
# Left-aligned (positive integer)
fzf --height=10 --border --border-label="╢ $label ╟" --border-label-pos=3
--color=label:italic:black
# Right-aligned (negative integer) on the bottom line (:bottom)
fzf --height=10 --border --border-label="╢ $label ╟" --border-label-pos=-3:bottom
--color=label:italic:black
--border-label-pos[=N[:top|bottom]]
Position of the border label on the border line. Specify a positive integer as the column position
from the left. Specify a negative integer to right-align the label. Label is printed on the top
border line by default, add :bottom to put it on the border line on the bottom. The default value
0 (or center) will put the label at the center of the border line.
LIST SECTION
-m, --multi[=MAX]
Enable multi-select with tab/shift-tab. It optionally takes an integer argument which denotes the
maximum number of items that can be selected.
+m, --no-multi
Disable multi-select
--highlight-line
Highlight the whole current line
--cycle
Enable cyclic scroll
--wrap Enable line wrap
--wrap-sign=INDICATOR
Indicator for wrapped lines. The default is '↳ ' or '> ' depending on --no-unicode.
--no-multi-line
Disable multi-line display of items when using --read0
--track
Make fzf track the current selection when the result list is updated. This can be useful when
browsing logs using fzf with sorting disabled. It is not recommended to use this option with --tac
as the resulting behavior can be confusing. Also, consider using track action instead of this
option.
e.g.
git log --oneline --graph --color=always | nl |
fzf --ansi --track --no-sort --layout=reverse-list
--tac Reverse the order of the input
e.g.
history | fzf --tac --no-sort
--gap[=N]
Render empty lines between each item
--gap-line[=STR]
The given string will be repeated to draw a horizontal line on each gap (default: '┈' or '-'
depending on --no-unicode).
--keep-right
Keep the right end of the line visible when it's too long. Effective only when the query string is
empty.
--scroll-off=LINES
Number of screen lines to keep above or below when scrolling to the top or to the bottom (default:
3).
--no-hscroll
Disable horizontal scroll
--hscroll-off=COLS
Number of screen columns to keep to the right of the highlighted substring (default: 10). Setting
it to a large value will cause the text to be positioned on the center of the screen.
--jump-labels=CHARS
Label characters for jump mode.
--pointer=STR
Pointer to the current line (default: '▌' or '>' depending on --no-unicode)
--marker=STR
Multi-select marker (default: '┃' or '>' depending on --no-unicode)
--marker-multi-line=STR
Multi-select marker for multi-line entries. 3 elements for top, middle, and bottom. (default:
'╻┃╹' or '.|'' depending on --no-unicode)
--ellipsis=STR
Ellipsis to show when line is truncated (default: '··')
--tabstop=SPACES
Number of spaces for a tab character (default: 8)
--scrollbar=CHAR1[CHAR2]
Use the given character to render scrollbar. (default: '│' or ':' depending on --no-unicode). The
optional CHAR2 is used to render scrollbar of the preview window.
--no-scrollbar
Do not display scrollbar. A synonym for --scrollbar=''
--list-border[=STYLE]
Draw border around the list section
--list-label[=LABEL]
Label to print on the list border
--list-label-pos[=N[:top|bottom]]
Position of the list label
INPUT SECTION
--no-input
Disable and hide the input section. You can no longer type in queries. To trigger a search, use
search action. You can later show the input section using show-input or toggle-input action, and
hide it again using hide-input, or toggle-input.
--prompt=STR
Input prompt (default: '> ')
--info=STYLE
Determines the display style of the finder info. (e.g. match counter, loading indicator, etc.)
default On the left end of the horizontal separator
right On the right end of the horizontal separator
hidden Do not display finder info
inline After the prompt with the default prefix ' < '
inline:PREFIX After the prompt with a non-default prefix
inline-right On the right end of the prompt line
inline-right:PREFIX On the right end of the prompt line with a custom prefix
--info-command=COMMAND
Command to generate the finder info line. The command runs synchronously and blocks the UI until
completion, so make sure that it's fast. ANSI color codes are supported. $FZF_INFO variable is set
to the original info text. For additional environment variables available to the command, see the
section ENVIRONMENT VARIABLES EXPORTED TO CHILD PROCESSES.
e.g.
# Prepend the current cursor position in yellow
fzf --info-command='echo -e "\x1b[33;1m$FZF_POS\x1b[m/$FZF_INFO 💛"'
--no-info
A synonym for --info=hidden
--separator=STR
The given string will be repeated to form the horizontal separator on the info line (default: '─'
or '-' depending on --no-unicode).
ANSI color codes are supported.
--no-separator
Do not display horizontal separator on the info line. A synonym for --separator=''
--filepath-word
Make word-wise movements and actions respect path separators. The following actions are affected:
backward-kill-word
backward-word
forward-word
kill-word
--input-border[=STYLE]
Draw border around the input section
--input-label[=LABEL]
Label to print on the input border
--input-label-pos[=N[:top|bottom]]
Position of the input label
PREVIEW WINDOW
--preview=COMMAND
Execute the given command for the current line and display the result on the preview window. {} in
the command is the placeholder that is replaced to the single-quoted string of the current line.
To transform the replacement string, specify field index expressions between the braces (See FIELD
INDEX EXPRESSION for the details).
e.g.
fzf --preview='head -$LINES {}'
ls -l | fzf --preview="echo user={3} when={-4..-2}; cat {-1}" --header-lines=1
fzf exports $FZF_PREVIEW_LINES and $FZF_PREVIEW_COLUMNS so that they represent the exact size of
the preview window. (It also overrides $LINES and $COLUMNS with the same values but they can be
reset by the default shell, so prefer to refer to the ones with FZF_PREVIEW_ prefix.)
fzf also exports $FZF_PREVIEW_TOP and $FZF_PREVIEW_LEFT so that the preview command can determine
the position of the preview window.
A placeholder expression starting with + flag will be replaced to the space-separated list of the
selected lines (or the current line if no selection was made) individually quoted.
e.g.
fzf --multi --preview='head -10 {+}'
git log --oneline | fzf --multi --preview 'git show {+1}'
When using a field index expression, leading and trailing whitespace is stripped from the
replacement string. To preserve the whitespace, use the s flag.
A placeholder expression with f flag is replaced to the path of a temporary file that holds the
evaluated list. This is useful when you multi-select a large number of items and the length of the
evaluated string may exceed ARG_MAX.
e.g.
# Press CTRL-A to select 100K items and see the sum of all the numbers.
# This won't work properly without 'f' flag due to ARG_MAX limit.
seq 100000 | fzf --multi --bind ctrl-a:select-all \
--preview "awk '{sum+=\$1} END {print sum}' {+f}"
Also,
* {q} is replaced to the current query string
* {q} can contain field index expressions. e.g. {q:1}, {q:2..}, etc.
* {n} is replaced to the zero-based ordinal index of the current item.
Use {+n} if you want all index numbers when multiple lines are selected.
Note that you can escape a placeholder pattern by prepending a backslash.
Preview window will be updated even when there is no match for the current query if any of the
placeholder expressions evaluates to a non-empty string or {q} is in the command template.
Since 0.24.0, fzf can render partial preview content before the preview command completes. ANSI
escape sequence for clearing the display (CSI 2 J) is supported, so you can use it to implement
preview window that is constantly updating.
e.g.
fzf --preview 'for i in $(seq 100000); do
(( i % 200 == 0 )) && printf "\033[2J"
echo "$i"
sleep 0.01
done'
fzf has experimental support for Kitty graphics protocol and Sixel graphics. The following
example uses https://github.com/junegunn/fzf/blob/master/bin/fzf-preview.sh script to render an
image using either of the protocols inside the preview window.
e.g.
fzf --preview='fzf-preview.sh {}'
--preview-border[=STYLE]
Short for --preview-window=border-STYLE. In addition to the other styles, line style is also
supported for preview border, which draws a single separator line between the preview window and
the rest of the interface.
--preview-label[=LABEL]
Label to print on the horizontal border line of the preview window. Should be used with one of
the following --preview-window options.
* border-rounded (default on non-Windows platforms)
* border-sharp (default on Windows)
* border-bold
* border-double
* border-block
* border-thinblock
* border-horizontal
* border-top
* border-bottom
--preview-label-pos[=N[:top|bottom]]
Position of the border label on the border line of the preview window. Specify a positive integer
as the column position from the left. Specify a negative integer to right-align the label. Label
is printed on the top border line by default, add :bottom to put it on the border line on the
bottom. The default value 0 (or center) will put the label at the center of the border line.
--preview-window=[POSITION][,SIZE[%]][,border-STYLE][,[no]wrap][,[no]follow][,[no]cycle][,[no]info][,[no]hidden][,+SCROLL[OFFSETS][/DENOM]][,~HEADER_LINES][,default][,<SIZE_THRESHOLD(ALTERNATIVE_LAYOUT)]
POSITION: (default: right)
up
down
left
right
Determines the layout of the preview window.
* If the argument contains :hidden, the preview window will be hidden by default until
toggle-preview action is triggered.
* If size is given as 0, preview window will not be visible, but fzf will still execute the
command in the background.
* Long lines are truncated by default. Line wrap can be enabled with wrap flag.
* Preview window will automatically scroll to the bottom when follow flag is set, similarly to how
tail -f works.
e.g.
fzf --preview-window follow --preview 'for i in $(seq 100000); do
echo "$i"
sleep 0.01
(( i % 300 == 0 )) && printf "\033[2J"
done'
* Cyclic scrolling is enabled with cycle flag.
* To hide the scroll offset information on the top right corner, specify noinfo.
* To change the style of the border of the preview window, specify one of the options for --border
with border- prefix. e.g. border-rounded (border with rounded edges, default), border-sharp
(border with sharp edges), border-left, border-none, etc.
* In addition to the other border styles, border-line style is also supported, which draws a
single separator line between the preview window and the rest of the interface.
* [:+SCROLL[OFFSETS][/DENOM]] determines the initial scroll offset of the preview window.
- SCROLL can be either a numeric integer or a single-field index expression that refers to a
numeric integer or {n} to refer to the zero-based ordinal index of the current item.
- The optional OFFSETS part is for adjusting the base offset. It should be given as a series of
signed integers (-INTEGER or +INTEGER).
- The final /DENOM part is for specifying a fraction of the preview window height.
* ~HEADER_LINES keeps the top N lines as the fixed header so that they are always visible.
* default resets all options previously set to the default.
e.g.
# Non-default scroll window positions and sizes
fzf --preview="head {}" --preview-window=up,30%
fzf --preview="file {}" --preview-window=down,1
# Initial scroll offset is set to the line number of each line of
# git grep output *minus* 5 lines (-5)
git grep --line-number '' |
fzf --delimiter : --preview 'nl {1}' --preview-window '+{2}-5'
# Preview with bat, matching line in the middle of the window below
# the fixed header of the top 3 lines
#
# ~3 Top 3 lines as the fixed header
# +{2} Base scroll offset extracted from the second field
# +3 Extra offset to compensate for the 3-line header
# /2 Put in the middle of the preview area
#
git grep --line-number '' |
fzf --delimiter : \
--preview 'bat --style=full --color=always --highlight-line {2} {1}' \
--preview-window '~3,+{2}+3/2'
# Display top 3 lines as the fixed header
fzf --preview 'bat --style=full --color=always {}' --preview-window '~3'
* You can specify an alternative set of options that are used only when the size
of the preview window is below a certain threshold. Note that only one
alternative layout is allowed.
e.g.
fzf --preview 'cat {}' --preview-window 'right,border-left,<30(up,30%,border-bottom)'
HEADER
--header=STR
The given string will be printed as the sticky header. The lines are displayed in the given order
from top to bottom regardless of --layout option, and are not affected by --with-nth. ANSI color
codes are processed even when --ansi is not set.
--header-lines=N
The first N lines of the input are treated as the sticky header. When --with-nth is set, the lines
are transformed just like the other lines that follow.
--header-first
Print header before the prompt line
--header-border[=STYLE]
Draw border around the header section
--header-label[=LABEL]
Label to print on the header border
--header-label-pos[=N[:top|bottom]]
Position of the header label
--header-lines-border[=STYLE]
Display header from --header-lines with a separate border. Pass none to still separate the header
lines but without a border. To combine two headers, use --no-header-lines-border.
SCRIPTING
-q, --query=STR
Start the finder with the given query
-1, --select-1
If there is only one match for the initial query (--query), do not start interactive finder and
automatically select the only match
-0, --exit-0
If there is no match for the initial query (--query), do not start interactive finder and exit
immediately
-f, --filter=STR
Filter mode. Do not start interactive finder. When used with --no-sort, fzf becomes a fuzzy-
version of grep.
--print-query
Print query as the first line
--expect=KEY[,..]
Comma-separated list of keys that can be used to complete fzf in addition to the default enter
key. When this option is set, fzf will print the name of the key pressed as the first line of its
output (or as the second line if --print-query is also used). The line will be empty if fzf is
completed with the default enter key. If --expect option is specified multiple times, fzf will
expect the union of the keys. --no-expect will clear the list.
e.g.
fzf --expect=ctrl-v,ctrl-t,alt-s --expect=f1,f2,~,@
This option is not compatible with --bind on the same key and will take precedence over it. To
combine the two, use print action.
e.g.
fzf --multi \
--bind 'enter:print()+accept,ctrl-y:select-all+print(ctrl-y)+accept'
--no-clear
Do not clear finder interface on exit. If fzf was started in full screen mode, it will not switch
back to the original screen, so you'll have to manually run tput rmcup to return. This option can
be used to avoid flickering of the screen when your application needs to start fzf multiple times
in order. (Note that in most cases, it is preferable to use reload action instead.)
e.g.
foo=$(seq 100 | fzf --no-clear) || (
# Need to manually switch back to the main screen when cancelled
tput rmcup
exit 1
) && seq "$foo" 100 | fzf
KEY/EVENT BINDING
--bind=BINDINGS
Comma-separated list of custom key/event bindings. See KEY/EVENT BINDINGS for the details.
ADVANCED
--with-shell=STR
Shell command and flags to start child processes with. On *nix Systems, the default value is
$SHELL -c if $SHELL is set, otherwise sh -c. On Windows, the default value is cmd /s/c when
$SHELL is not set.
--listen[=[ADDR:]PORT] --listen-unsafe[=[ADDR:]PORT]
Start HTTP server and listen on the given address. It allows external processes to send actions to
perform via POST method.
- If the port number is omitted or given as 0, fzf will automatically choose a port and export it
as FZF_PORT environment variable to the child processes
- If FZF_API_KEY environment variable is set, the server would require sending an API key with the
same value in the x-api-key HTTP header
- FZF_API_KEY is required for a non-localhost listen address
- To allow remote process execution, use --listen-unsafe
e.g.
# Start HTTP server on port 6266
fzf --listen 6266
# Send action to the server
curl -XPOST localhost:6266 -d 'reload(seq 100)+change-prompt(hundred> )'
# Get program state in JSON format (experimental)
# * Make sure NOT to access this endpoint from execute/transform actions
# as it will result in a timeout
curl localhost:6266
# Start HTTP server on port 6266 with remote connections allowed
# * Listening on non-localhost address requires using an API key
export FZF_API_KEY="$(head -c 32 /dev/urandom | base64)"
fzf --listen 0.0.0.0:6266
# Send an authenticated action
curl -XPOST localhost:6266 -H "x-api-key: $FZF_API_KEY" -d 'change-query(yo)'
# Choose port automatically and export it as $FZF_PORT to the child process
fzf --listen --bind 'start:execute-silent:echo $FZF_PORT > /tmp/fzf-port'
DIRECTORY TRAVERSAL
--walker=[file][,dir][,follow][,hidden]
Determines the behavior of the built-in directory walker that is used when $FZF_DEFAULT_COMMAND is
not set. The default value is file,follow,hidden.
* file: Include files in the search result
* dir: Include directories in the search result
* hidden: Include and follow hidden directories
* follow: Follow symbolic links
--walker-root=DIR [...]
List of directory names to start the built-in directory walker. The default value is the current
working directory.
--walker-skip=DIRS
Comma-separated list of directory names to skip during the directory walk. The default value is
.git,node_modules.
HISTORY
--history=HISTORY_FILE
Load search history from the specified file and update the file on completion. When enabled,
CTRL-N and CTRL-P are automatically remapped to next-history and prev-history.
--history-size=N
Maximum number of entries in the history file (default: 1000). The file is automatically truncated
when the number of the lines exceeds the value.
e.g. gem list | fzf --with-shell 'ruby -e' --preview 'pp Gem::Specification.find_by_name({1})'
SHELL INTEGRATION
--bash Print script to set up Bash shell integration
e.g. eval "$(fzf --bash)"
--zsh Print script to set up Zsh shell integration
e.g. source <(fzf --zsh)
--fish Print script to set up Fish shell integration
e.g. fzf --fish | source
OTHERS
--no-mouse
Disable mouse
--no-unicode
Use ASCII characters instead of Unicode drawing characters to draw borders, the spinner and the
horizontal separator.
--ambidouble
Set this option if your terminal displays ambiguous width characters (e.g. box-drawing characters
for borders) as 2 columns.
HELP
--version
Display version information and exit
--help Show help message
--man Show man page
ENVIRONMENT VARIABLES
FZF_DEFAULT_COMMAND
Default command to use when input is a TTY device. On *nix systems, fzf runs the command with
$SHELL -c if SHELL is set, otherwise with sh -c, so in this case make sure that the command is
POSIX-compliant.
FZF_DEFAULT_OPTS
Default options.
e.g. export FZF_DEFAULT_OPTS="--layout=reverse --border --cycle"
FZF_DEFAULT_OPTS_FILE
The location of the file that contains the default options.
e.g. export FZF_DEFAULT_OPTS_FILE=~/.fzfrc
FZF_API_KEY
Can be used to require an API key when using --listen option. If not set, no authentication will
be required by the server. You can set this value if you need to protect against DNS rebinding and
privilege escalation attacks.
EXIT STATUS
0 Normal exit
1 No match
2 Error
126 Permission denied error from become action
127 Invalid shell command for become action
130 Interrupted with CTRL-C or ESC
FIELD INDEX EXPRESSION
A field index expression can be a non-zero integer or a range expression ([BEGIN]..[END]). --nth and
--with-nth take a comma-separated list of field index expressions.
Examples
1 The 1st field
2 The 2nd field
-1 The last field
-2 The 2nd to last field
3..5 From the 3rd field to the 5th field
2.. From the 2nd field to the last field
..-3 From the 1st field to the 3rd to the last field
.. All the fields
ENVIRONMENT VARIABLES EXPORTED TO CHILD PROCESSES
fzf exports the following environment variables to its child processes.
FZF_LINES Number of lines fzf takes up excluding padding and margin
FZF_COLUMNS Number of columns fzf takes up excluding padding and margin
FZF_TOTAL_COUNT Total number of items
FZF_MATCH_COUNT Number of matched items
FZF_SELECT_COUNT Number of selected items
FZF_POS Vertical position of the cursor in the list starting from 1
FZF_QUERY Current query string
FZF_INPUT_STATE Current input state (enabled, disabled, hidden)
FZF_NTH Current --nth option
FZF_PROMPT Prompt string
FZF_PREVIEW_LABEL Preview label string
FZF_BORDER_LABEL Border label string
FZF_ACTION The name of the last action performed
FZF_KEY The name of the last key pressed
FZF_PORT Port number when --listen option is used
FZF_PREVIEW_TOP Top position of the preview window
FZF_PREVIEW_LEFT Left position of the preview window
FZF_PREVIEW_LINES Number of lines in the preview window
FZF_PREVIEW_COLUMNS Number of columns in the preview window
EXTENDED SEARCH MODE
Unless specified otherwise, fzf will start in "extended-search mode". In this mode, you can specify
multiple patterns delimited by spaces, such as: 'wild ^music .mp3$ sbtrkt !rmx
You can prepend a backslash to a space (\ ) to match a literal space character.
Exact-match (quoted)
A term that is prefixed by a single-quote character (') is interpreted as an "exact-match" (or
"non-fuzzy") term. fzf will search for the exact occurrences of the string.
Anchored-match
A term can be prefixed by ^, or suffixed by $ to become an anchored-match term. Then fzf will search for
the lines that start with or end with the given string. An anchored-match term is also an exact-match
term.
Exact-boundary-match (quoted both ends)
A single-quoted term is interpreted as an "exact-boundary-match". fzf will search for the exact
occurrences of the string with both ends at the word boundaries. Unlike in regular expressions, this also
sees an underscore as a word boundary. But the words around underscores are ranked lower and appear later
in the result than the other words around the other types of word boundaries.
1. xxx foo xxx (highest score)
2. xxx foo_xxx
3. xxx_foo xxx
4. xxx_foo_xxx (lowest score)
Negation
If a term is prefixed by !, fzf will exclude the lines that satisfy the term from the result. In this
case, fzf performs exact match by default.
Exact-match by default
If you don't prefer fuzzy matching and do not wish to "quote" (prefixing with ') every word, start fzf
with -e or --exact option. Note that when --exact is set, '-prefix "unquotes" the term.
OR operator
A single bar character term acts as an OR operator. For example, the following query matches entries that
start with core and end with either go, rb, or py.
e.g. ^core go$ | rb$ | py$
KEY/EVENT BINDINGS
--bind option allows you to bind a key or an event to one or more actions. You can use it to customize
key bindings or implement dynamic behaviors.
--bind takes a comma-separated list of binding expressions. Each binding expression is KEY:ACTION or
EVENT:ACTION. You can bind actions to multiple keys and events by writing comma-separated list of keys
and events before the colon. e.g. KEY1,KEY2,EVENT1,EVENT2:ACTION.
e.g.
fzf --bind=ctrl-j:accept,ctrl-k:kill-line
# Load 'ps -ef' output on start and reload it on CTRL-R
fzf --bind 'start,ctrl-r:reload:ps -ef'

AVAILABLE EVENTS:
start
Triggered only once when fzf finder starts. Since fzf consumes the input stream asynchronously,
the input list is not available unless you use --sync.
e.g.
# Move cursor to the last item and select all items
seq 1000 | fzf --multi --sync --bind start:last+select-all
load
Triggered when the input stream is complete and the initial processing of the list is complete.
e.g.
# Change the prompt to "loaded" when the input stream is complete
(seq 10; sleep 1; seq 11 20) | fzf --prompt 'Loading> ' --bind 'load:change-prompt:Loaded> '
resize
Triggered when the terminal size is changed.
e.g.
fzf --bind 'resize:transform-header:echo Resized: ${FZF_COLUMNS}x${FZF_LINES}'
result
Triggered when the filtering for the current query is complete and the result list is ready.
e.g.
# Put the cursor on the second item when the query string is empty
# * Note that you can't use 'change' event in this case because the second position may not
be available
fzf --sync --bind 'result:transform:[[ -z {q} ]] && echo "pos(2)"'
change
Triggered whenever the query string is changed
e.g.
# Move cursor to the first entry whenever the query is changed
fzf --bind change:first
focus
Triggered when the focus changes due to a vertical cursor movement or a search result update.
e.g.
fzf --bind 'focus:transform-preview-label:echo [ {} ]' --preview 'cat {}'
# Any action bound to the event runs synchronously and thus can make the interface sluggish
# e.g. lolcat isn't one of the fastest programs, and every cursor movement in
# fzf will be noticeably affected by its execution time
fzf --bind 'focus:transform-preview-label:echo [ {} ] | lolcat -f' --preview 'cat {}'
# Beware not to introduce an infinite loop
seq 10 | fzf --bind 'focus:up' --cycle
one
Triggered when there's only one match. one:accept binding is comparable to --select-1 option, but
the difference is that --select-1 is only effective before the interactive finder starts but one
event is triggered by the interactive finder.
e.g.
# Automatically select the only match
seq 10 | fzf --bind one:accept
zero
Triggered when there's no match. zero:abort binding is comparable to --exit-0 option, but the
difference is that --exit-0 is only effective before the interactive finder starts but zero event
is triggered by the interactive finder.
e.g.
# Reload the candidate list when there's no match
echo $RANDOM | fzf --bind 'zero:reload(echo $RANDOM)+clear-query' --height 3
backward-eof
Triggered when the query string is already empty and you try to delete it backward.
e.g.
fzf --bind backward-eof:abort
jump
Triggered when successfully jumped to the target item in jump mode.
e.g.
fzf --bind space:jump,jump:accept
jump-cancel
Triggered when jump mode is cancelled.
e.g.
fzf --bind space:jump,jump:accept,jump-cancel:abort
click-header
Triggered when a mouse click occurs within the header. Sets FZF_CLICK_HEADER_LINE and
FZF_CLICK_HEADER_COLUMN environment variables starting from 1. It optionally sets
FZF_CLICK_HEADER_WORD and FZF_CLICK_HEADER_NTH if clicked on a word.
e.g.
# Click on the header line to limit search scope
ps -ef | fzf --style full --layout reverse --header-lines 1 \
--header-lines-border bottom --no-list-border \
--color fg:dim,nth:regular \
--bind 'click-header:transform-nth(
echo $FZF_CLICK_HEADER_NTH
)+transform-prompt(
echo "$FZF_CLICK_HEADER_WORD> "
)'

ACTION COMPOSITION
Multiple actions can be chained using + separator.
e.g.
fzf --multi --bind 'ctrl-a:select-all+accept'
fzf --multi --bind 'ctrl-a:select-all' --bind 'ctrl-a:+accept'
Any action after a terminal action that exits fzf, such as accept or abort, is ignored.
ACTION ARGUMENT
An action denoted with (...) suffix takes an argument.
e.g.
fzf --bind 'ctrl-a:change-prompt(NewPrompt> )'
fzf --bind 'ctrl-v:preview(cat {})' --preview-window hidden
If the argument contains parentheses, fzf may fail to parse the expression. In that case, you can use any
of the following alternative notations to avoid parse errors.
action-name[...]
action-name{...}
action-name<...>
action-name~...~
action-name!...!
action-name@...@
action-name#...#
action-name$...$
action-name%...%
action-name^...^
action-name&...&
action-name*...*
action-name;...;
action-name/.../
action-name|...|
action-name:...
The last one is the special form that frees you from parse errors as it does not expect the
closing character. The catch is that it should be the last one in the comma-separated list of key-
action pairs.
COMMAND EXECUTION
With execute(...) action, you can execute arbitrary commands without leaving fzf. For example, you can
turn fzf into a simple file browser by binding enter key to less command like follows.
fzf --bind "enter:execute(less {})"
You can use the same placeholder expressions as in --preview.
fzf switches to the alternate screen when executing a command. However, if the command is expected to
complete quickly, and you are not interested in its output, you might want to use execute-silent instead,
which silently executes the command without the switching. Note that fzf will not be responsive until the
command is complete. For asynchronous execution, start your command as a background process (i.e.
appending &).
On *nix systems, fzf runs the command with $SHELL -c if SHELL is set, otherwise with sh -c, so in this
case make sure that the command is POSIX-compliant.
become(...) action is similar to execute(...), but it replaces the current fzf process with the specified
command using execve(2) system call.
fzf --bind "enter:become(vim {})"
RELOAD INPUT
reload(...) action is used to dynamically update the input list without restarting fzf. It takes the same
command template with placeholder expressions as execute(...).
See https://github.com/junegunn/fzf/issues/1750 for more info.
e.g.
# Update the list of processes by pressing CTRL-R
ps -ef | fzf --bind 'ctrl-r:reload(ps -ef)' --header 'Press CTRL-R to reload' \
--header-lines=1 --layout=reverse
# Integration with ripgrep
RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case "
INITIAL_QUERY="foobar"
FZF_DEFAULT_COMMAND="$RG_PREFIX '$INITIAL_QUERY'" \
fzf --bind "change:reload:$RG_PREFIX {q} || true" \
--ansi --disabled --query "$INITIAL_QUERY"
reload-sync(...) is a synchronous version of reload that replaces the list only when the command is
complete. This is useful when the command takes a while to produce the initial output and you don't want
fzf to run against an empty list while the command is running.
e.g.
# You can still filter and select entries from the initial list for 3 seconds
seq 100 | fzf --bind 'load:reload-sync(sleep 3; seq 1000)+unbind(load)'
TRANSFORM ACTIONS
Actions with transform- prefix are used to transform the states of fzf using the output of an external
command. The output of these commands are expected to be a single line of text.
e.g.
fzf --bind 'focus:transform-header:file --brief {}'
transform(...) action runs an external command that should print a series of actions to be performed. The
output should be in the same format as the payload of HTTP POST request to the --listen server.
e.g.
# Disallow selecting an empty line
echo -e "1. Hello\n2. Goodbye\n\n3. Exit" |
fzf --height '~100%' --reverse --header 'Select one' \
--bind 'enter:transform:[[ -n {} ]] &&
echo accept ||
echo "change-header:Invalid selection"'
PREVIEW BINDING
With preview(...) action, you can specify multiple different preview commands in addition to the default
preview command given by --preview option.
e.g.
# Default preview command with an extra preview binding
fzf --preview 'file {}' --bind '?:preview:cat {}'
# A preview binding with no default preview command
# (Preview window is initially empty)
fzf --bind '?:preview:cat {}'
# Preview window hidden by default, it appears when you first hit '?'
fzf --bind '?:preview:cat {}' --preview-window hidden
CHANGE PREVIEW WINDOW ATTRIBUTES
change-preview-window action can be used to change the properties of the preview window. Unlike the
--preview-window option, you can specify multiple sets of options separated by '|' characters.
e.g.
# Rotate through the options using CTRL-/
fzf --preview 'cat {}' --bind
'ctrl-/:change-preview-window(right,70%|down,40%,border-horizontal|hidden|right)'
# The default properties given by `--preview-window` are inherited, so an empty string in the list
is interpreted as the default
fzf --preview 'cat {}' --preview-window 'right,40%,border-left' --bind
'ctrl-/:change-preview-window(70%|down,border-top|hidden|)'
# This is equivalent to toggle-preview action
fzf --preview 'cat {}' --bind 'ctrl-/:change-preview-window(hidden|)'
