DESCRIPTION
Fasd keeps track of files and directories you access in your shell and gives you quick
access to them. You can use fasd to reference files or directories by just a few key
identifying characters. You can use fasd to boost your command line productivity by
defining your own aliases to launch programs on files or directories. Fasd, by default,
provides some basic aliases, including a shell function "z" that resembles the
functionality of "z" and "autojump."
The name "fasd" comes from the default suggested aliases f(files), a(files/directories),
s(show/search/select), d(directories).
Fasd ranks files and directories by "frecency," that is, by both "frequency" and
"recency." The term "frecency" was first coined by Mozilla and used in Firefox.
EXAMPLES
z bundle
f -e vim nginx conf
f -i rc$
vi `f nginx conf`
cp update.html `d www`
open `sf pdf`
SHELL INITIALIZATION
To get fasd working in a shell, some initialization code must be run. Put lines below in
your POSIX compatible shell rc.
eval "$(fasd --init auto)"
This will setup a command hook that executes on every command and advanced tab completion
for zsh and bash.
If you want more control over what gets into your shell environment, you can pass
customized set of arguments to fasd --init.
zsh-hook # define _fasd_preexec and add it to zsh preexec array
zsh-ccomp # zsh command mode completion definitions
zsh-ccomp-install # setup command mode completion for zsh
zsh-wcomp # zsh word mode completion definitions
zsh-wcomp-install # setup word mode completion for zsh
bash-hook # add hook code to bash $PROMPT_COMMAND
bash-ccomp # bash command mode completion definitions
bash-ccomp-install # setup command mode completion for bash
posix-alias # define aliases that applies to all posix shells
posix-hook # setup $PS1 hook for shells that's posix compatible
tcsh-alias # define aliases for tcsh
tcsh-hook # setup tcsh precmd alias
Example for a minimal zsh setup (no tab completion):
eval "$(fasd --init posix-alias zsh-hook)"
Note that this method will slightly increase your shell start-up time, since calling
binaries has overhead. You can cache fasd init code if you want minimal overhead.
Example code for bash (to be put into .bashrc):
fasd_cache="$HOME/.fasd-init-bash"
if [ "$(command -v fasd)" -nt "$fasd_cache" -o ! -s "$fasd_cache" ]; then
fasd --init posix-alias bash-hook bash-ccomp bash-ccomp-install >| "$fasd_cache"
fi
source "$fasd_cache"
unset fasd_cache
Optionally, if you can also source fasd if you want fasd to be a shell function instead of
an executable.
You can tweak initialization code. For instance, if you want to use "c" instead of "z" to
do directory jumping, you can use the alias below:
alias c='fasd_cd -d'
# `-d' option present for bash completion
# function fasd_cd is defined in posix-alias
MATCHING
Fasd has three matching modes: default, case-insensitive, and fuzzy.
For a given set of queries (the set of command-line arguments passed to fasd), a path is a
match if and only if:
1. Queries match the path in order.
2. The last query matches the last segment of the path.
If no match is found, fasd will try the same process ignoring case. If still no match is
found, fasd will allow extra characters to be placed between query characters for fuzzy
matching.
Tips:
• If you want your last query not to match the last segment of the path, append `/' as the
last query.
• If you want your last query to match the end of the filename, append `$' to the last
query.
COMPATIBILITY
Fasd's basic functionalities are POSIX compliant, meaning that you should be able to use
fasd in all POSIX compliant shells. Your shell need to support command substitution in
$PS1 in order for fasd to automatically track your commands and files. This feature is
not specified by the POSIX standard, but it's nonetheless present in many POSIX compliant
shells. In shells without prompt command or prompt command substitution (tcsh for
instance), you can add entries manually with "fasd -A". You are very welcomed to
contribute shell initialization code for not yet supported shells.
TAB COMPLETION
Fasd offers two completion modes, command mode completion and word mode completion.
Command mode completion works in bash and zsh. Word mode completion only works in zsh.
Command mode completion is just like completion for any other commands. It is triggered
when you hit tab on a fasd command or its aliases. Under this mode your queries can be
separated by a space. Tip: if you find that the completion result overwrites your
queries, type an extra space before you hit tab.
Word mode completion can be triggered on any command. Word completion is triggered by any
command line argument that starts with "," (all), "f," (files), or "d," (directories), or
that ends with ",," (all), ",,f" (files), or ",,d" (directories). Examples:
$ vim ,rc,lo<Tab>
$ vim /etc/rc.local
$ mv index.html d,www<Tab>
$ mv index.html /var/www/
There are also three zle widgets: "fasd-complete", "fasd-complete-f", "fasd-complete-d".
You can bind them to keybindings you like:
bindkey '^X^A' fasd-complete # C-x C-a to do fasd-complete (fils and directories)
bindkey '^X^F' fasd-complete-f # C-x C-f to do fasd-complete-f (only files)
bindkey '^X^D' fasd-complete-d # C-x C-d to do fasd-complete-d (only directories)
BACKENDS
Fasd can take advantage of different sources of recent / frequent files. Most desktop
environments (like Gtk) and some editors (like Vim) keep a list of accessed files. Fasd
can use them as additional backends if the data can be converted into fasd's native
format. As of now, fasd supports Gtk's recently-used.xbel and Vim's viminfo backends.
You can define your own backend by declaring a function by that name in your .fasdrc. You
set default backend with _FASD_BACKENDS variable in our .fasdrc.
TWEAKS
Upon every execution, fasd will source "/etc/fasdrc" and "$HOME/.fasdrc" if they are
present. Below are some variables you can set:
$_FASD_DATA
Path to the fasd data file, default "$HOME/.fasd".
$_FASD_BLACKLIST
List of blacklisted strings. Commands matching them will not be processed.
Default is "--help".
$_FASD_SHIFT
List of all commands that needs to be shifted, defaults to "sudo busybox".
$_FASD_IGNORE
List of all commands that will be ignored, defaults to "fasd ls echo".
$_FASD_TRACK_PWD
Fasd defaults to track your "$PWD". Set this to 0 to disable this behavior.
$_FASD_AWK
Which awk to use. fasd can detect and use a compatible awk.
$_FASD_SINK
File to log all STDERR to, defaults to "/dev/null".
$_FASD_MAX
Max total score / weight, defaults to 2000.
$_FASD_SHELL
Which shell to execute. Some shells will run faster than others. fasd
runs faster with dash and ksh variants.
$_FASD_BACKENDS
Default backends.
$_FASD_RO
If set to any non-empty string, fasd will not add or delete entries from
database. You can set and export this variable from command line.
$_FASD_FUZZY
Level of "fuzziness" when doing fuzzy matching. More precisely, the number of
characters that can be skipped to generate a match. Set to empty or 0 to
disable fuzzy matching. Default value is 2.
$_FASD_VIMINFO
Path to .viminfo file for viminfo backend, defaults to "$HOME/.viminfo"
$_FASD_RECENTLY_USED_XBEL
Path to XDG recently-used.xbel file for recently-used backend, defaults to
"$HOME/.local/share/recently-used.xbel"
DEBUGGING
Fasd is hosted on GitHub: https://github.com/clvv/fasd
If fasd does not work as expected, please file a bug report on GitHub describing the
unexpected behavior along with your OS version, shell version, awk version, sed version,
and a log file.
You can set _FASD_SINK in your .fasdrc to obtain a log.
_FASD_SINK="$HOME/.fasd.log"
