OPERATIONAL NOTES
1. The database file is stored in:
- $XDG_DATA_HOME/buku/bookmarks.db, if XDG_DATA_HOME is defined (first preference)
or
- $HOME/.local/share/buku/bookmarks.db, if HOME is defined (second preference) or
- %APPDATA%kkmarks.db, if you are on Windows or
- the current directory.
2. If the URL contains characters like ';', '&' or brackets they may be interpreted
specially by the shell. To avoid it, add the URL within single or double quotes ('/").
3. URLs are unique in DB. The same URL cannot be added twice.
4. Bookmarks with immutable titles are listed with '(L)' after the title.
5. Tags:
- Comma (',') is the tag delimiter in DB. A tag cannot have comma(s) in it. Tags are
filtered (for unique tags) and sorted. Tags are stored in lower case and can be
replaced, appended or deleted.
- Folder names are converted to all-lowercase tags during bookmarks html import.
- Releases prior to v2.7 support both capital and lower cases in tags. From v2.7 all
tags are stored in lowercase. An undocumented option --fixtags is introduced to modify
the older tags. It also fixes another issue where the same tag appears multiple times
in the tagset of a record. Run buku --fixtags once.
- Tags can be edited from the prompt very easily using '>>' (append), '>'
(overwrite) and '<<' (remove) symbols. The LHS of the operands denotes the indices and
ranges of tags to apply (as listed by --tag or key 't' at prompt) and the RHS denotes
the actual DB indices and ranges of the bookmarks to apply the change to.
6. Update operation:
- If --title, --tag or --comment is passed without argument, clear the corresponding
field from DB.
- If --url is passed (and --title is omitted), update the title from web using the
URL.
- If indices are passed without any other options (--url, --title, --tag, --comment
and --immutable), read the URLs from DB and update titles from web. Bookmarks marked
immutable are skipped.
- Can update bookmarks matching a search, when combined with any of the search
options and no arguments to update are passed.
7. Delete operation:
- When a record is deleted, the last record is moved to the index.
- Delete doesn't work with range and indices provided together as arguments. It's an
intentional decision to avoid extra sorting, in-range checks and to keep the auto-DB
compaction functionality intact. On the same lines, indices are deleted in descending
order.
- Can delete bookmarks matching a search, when combined with any of the search
options and no arguments to delete are passed.
8. Search works in mysterious ways:
- Case-insensitive.
- Matches words in URL, title and tags.
- --sany : match any of the keywords in URL, title or tags. Default search option.
- --sall : match all the keywords in URL, title or tags.
- --deep : match substrings (`match` matches `rematched`) in URL, title and tags.
- --sreg : match a regular expression (ignores --deep).
- --stag : search bookmarks by tags, or list all tags alphabetically with usage
count (if no arguments). Delimit the list of tags in the query with `,` to search for
bookmarks that match ANY of the listed tags. Delimit tags with `+` to search for
bookmarks that match ALL of the listed tags. Note that `,` and `+` cannot be used
together in the same search. Exclude bookmarks matching certain tags from the results
by using ` - ` followed by the tags. Note that the ` - ` operator and the ` + `
delimiter must be space separated: ` - ` instead of `-` and ` + ` instead of `+`. This
is to distinguish them from hyphenated tags (e.g., `some-tag-name`) and tags with '+'s
(e.g., `some+tag+name`).
- Search for keywords along with tag filtering is possible. Two searches are issued
(one for keywords and another for tags) and the intersection of the 2 sets is returned
as the resultset.
- Search results are indexed incrementally. This index is different from actual
database index of a bookmark record which is shown within '[]' after the title.
- Results for any keyword matches are ordered by the number of keyword matches -
results matching more keywords (match score) will appear earlier in the list. Results
having the same number of matches will be ranked by their record DB index. If only one
keyword is searched, results will be ordered by DB index, since all matching records
will have the same match score.
9. Import:
- Auto-import looks in the default installation path and default user profile.
- URLs starting with `place:`, `file://` and `apt:` are ignored during import.
- Folder names are automatically imported as tags if --tacit is used.
- An auto-generated tag in the format 'YYYYMonDD' is added if --tacit is not used in
html or markdown import.
10. Encryption is optional and manual. AES256 algorithm is used. To use encryption, the
database file should be unlocked (-k) before using buku and locked (-l) afterwards.
Between these 2 operations, the database file lies unencrypted on the disk, and NOT in
memory. Also, note that the database file is unencrypted on creation.
11. Editor support:
- A single bookmark can be edited before adding. The editor can be set using the
environment variable *EDITOR* or by explicitly specifying the editor. The latter takes
precedence. If -a is used along with -w, the details are populated in the editor
template.
- In case of edit and update (a single bookmark), the existing record details are
fetched from DB and populated in the editor template. The environment variable EDITOR
must be set. Note that -u works independently of -w.
- All lines beginning with "#" will be stripped. Then line 1 will be treated as the
URL, line 2 will be the title, line 3 will be comma separated tags, and the rest of
the lines will be parsed as descriptions.
12. Proxy support: please refer to the ENVIRONMENT section.
GENERAL OPTIONS
-a --add URL [tag, ...]
Bookmark URL along with comma-separated tags. A tag can have multiple words.
-u --update [...]
Update fields of the bookmarks at specified indices in DB. If no arguments are
specified, all titles are refreshed from the web. Works with update modifiers for
the fields url, title, tag and comment. If only indices are passed without any edit
options, titles are fetched and updated (if not empty). Accepts hyphenated ranges
and space-separated indices. Updates search results when used with search options,
if no arguments.
-w --write [editor|index]
Edit a bookmark in editor before adding it. To edit and update an existing
bookmark, the index should be passed. However, in this case the environment
variable EDITOR must be set. The last record is opened in EDITOR if index=-1.
-d --delete [...]
Delete bookmarks. Accepts space-separated list of indices (e.g. 5 6 23 4 110 45) or
a single hyphenated range (e.g. 100-200). Note that range and list don't work
together. Deletes search results when combined with search options, if no
arguments.
-v --version
Show program version and exit.
-h --help
Show program help and exit.
EDIT OPTIONS
--url [...]
Specify the URL, works with --update only. Fetches and updates title if --title is
not used.
--tag [+|-] [...]
Specify comma separated tags, works with --add, --update. Clears the tags, if no
arguments passed. Appends or deletes tags, if list of tags is preceded by '+' or
'-' respectively.
--title [...]
Manually specify the title, works with --add, --update. Omits or clears the title,
if no arguments passed.
-c --comment [...]
Add notes or description of the bookmark, works with --add, --update. Clears the
comment, if no arguments passed.
--immutable N
Set the title of a bookmark immutable during updates. Works with --add, --update.
N=1 sets the immutable flag, N=0 removes it. If omitted, bookmarks are added with
N=0.
SEARCH OPTIONS
-s --sany keyword [...]
Search bookmarks with ANY of the keyword(s) in URL, title or tags and show the
results. Prompts to enter result number to open in browser. Note that the
sequential result index is not the DB index. The DB index is shown within '[]'
after the title.
This is the default search option for positional arguments if no other search
option is specified.
-S --sall keyword [...]
Search bookmarks with ALL keywords in URL, title or tags and show the results.
Behaviour same as --sany.
Special keywords:
"blank": list entries with empty title/tag
"immutable": list entries with locked title
NOTE: To search the keywords, use --sany
--deep Search modifier to match substrings. Works with --sany, --sall.
-r --sreg expression
Scan for a regular expression match.
-t --stag [tag [,|+] ...] [- tag, ...]
Search bookmarks by tags.
Use ',' delimiter to find entries matching ANY of the tags
Use ' + ' delimiter to find entries matching ALL of the tags. (Note that the ' + '
delimiter must be space separated)
NOTE: Cannot combine ',' and '+' in the same search
Use ' - ' to exclude bookmarks that match the tags that follow. (Note that the '-'
operator must be space separated).
List all tags alphabetically, if no arguments. The usage count (number of bookmarks
having the tag) is shown within first brackets.
-x --exclude keyword [...]
Exclude bookmarks matching the specified keywords. Works with --sany, --sall,
--sreg and --stag.
ENCRYPTION OPTIONS
-l --lock [N]
Encrypt (lock) the DB file with N (> 0, default 8) hash passes to generate key.
-k --unlock [N]
Decrypt (unlock) the DB file with N (> 0, default 8) hash passes to generate key.
POWER OPTIONS
--ai Auto-import bookmarks from Firefox, Google Chrome and Chromium browsers.
-e --export file
Export bookmarks to Firefox bookmarks formatted HTML. Works with --tag to export
only specific tags. Markdown is used if file has extension '.md'.
Markdown format: [title](url), 1 entry per line. A buku database is generated if
file has extension '.db'.
-i --import file
Import bookmarks from Firefox bookmarks formatted html. file is considered
Markdown (compliant with --export format) if it has '.md' extension or another buku
database if the extension is '.db'.
-p --print [...]
Show details (DB index, URL, title, tags and comment) of bookmark record by DB
index. If no arguments, all records with actual index from DB are shown. Accepts
hyphenated ranges and space-separated indices. A negative value (introduced for
convenience) behaves like the tail utility, e.g., -n shows the details of the last
n bookmarks.
-f --format N
Show selective monochrome output with specific fields. Works with --print. Search
results honour the option when used along with --json. Useful for creating batch
scripts.
N = 1, show only URL.
N = 2, show URL and tags in a single line.
N = 3, show only title.
N = 4, show URL, title and tags in a single line
To omit DB index from printed results, use N0, e.g., 10, 20, 30, 40.
-j --json
Output data formatted as json, works with --print output and search results.
--colors COLORS
Set output colors. Refer to the COLORS section below for details.
--nc Disable color output in all messages. Useful on terminals which can't handle ANSI
color codes or scripted environments.
--np Do not show the prompt, run and exit.
-o --open [...]
Open bookmarks by DB indices or ranges in browser. Open a random index if argument
is omitted.
--oa Open all search results immediately in the browser. Works best with --np. When used
along with --update or --delete, URLs are opened in the browser first and then
modified or deleted.
--replace old new
Replace old tag with new tag if both are passed; delete old tag if new tag is not
specified.
--shorten index|URL
Shorten the URL at DB index or an independent URL using the tny.im URL shortener
service.
--expand index|URL
Expand the URL at DB index or an independent URL shortened using tny.im.
--suggest
Show a list of similar tags to choose from when adding a new bookmark.
--tacit
Show lesser output. Reduces the verbosity of certain operations like add, update
etc.
--threads
Maximum number of parallel network connection threads to use during full DB
refresh. By default 4 connections are spawned. N can range from 1 to 10.
-V Check the latest upstream version available. This is FYI. It is possible the latest
upstream released version is still not available in your package manager as the
process takes a while.
-z --debug
Show debug information and additional logs.
PROMPT KEYS
1-N Browse search results by indices and ranges.
a Open all search results in browser.
s keyword [...]
Search for records with ANY keyword.
S keyword [...]
Search for records with ALL keywords.
d Toggle deep search to match substrings ('pen' matches 'opened').
r expression
Run a regular expression search.
t [...]

COLORS
buku allows you to customize the color scheme via a five-letter string, reminiscent of BSD
LSCOLORS. The five letters represent the colors of
- index
- title
- URL
- description/comment/note
- tag
respectively. The five-letter string is passed is as the argument to the --colors option,
or as the value of the environment variable BUKU_COLORS.
We offer the following colors/styles:
┌───────┬───────────────────────────────────────────────────┐
│Letter │ Color/Style │
├───────├───────────────────────────────────────────────────┤
│a │ black │
│b │ red │
│c │ green │
│d │ yellow │
│e │ blue │
│f │ magenta │
│g │ cyan │
│h │ white │
│i │ bright black │
│j │ bright red │
│k │ bright green │
│l │ bright yellow │
│m │ bright blue │
│n │ bright magenta │
│o │ bright cyan │
│p │ bright white │
│A-H │ bold version of the lowercase-letter color │
│I-P │ bold version of the lowercase-letter bright color │
│x │ normal │
│X │ bold │
│y │ reverse video │
│Y │ bold reverse video │
└───────┴───────────────────────────────────────────────────┘
The default colors string is oKlxm, which stands for
- bright cyan index
- bold bright green title
- bright yellow URL
- normal description
- bright blue tag
Note that
- Bright colors (implemented as \x1b[90m - \x1b[97m) may not be available in all color-
capable terminal emulators;
- Some terminal emulators draw bold text in bright colors instead;
- Some terminal emulators only distinguish between bold and bright colors via a default-
off switch.
Please consult the manual of your terminal emulator as well as
https://en.wikipedia.org/wiki/ANSI_escape_code for details.
EXAMPLES
1. Edit and add a bookmark from editor:
buku -w
buku -w 'gedit -w'
buku -w 'macvim -f' -a https://ddg.gg search engine, privacy
The first command picks editor from the environment variable EDITOR. The second
command opens gedit in blocking mode. The third command opens macvim with option -f
and the URL and tags populated in template.
2. Add a bookmark with tags 'search engine' and 'privacy', comment 'Search engine with
perks', fetch page title from the web:
buku -a https://ddg.gg search engine, privacy -c Search engine with perks
In the output, >: url, +: comment, #: tags.
3. Add a bookmark with tags 'search engine' & 'privacy' and immutable custom title 'DDG':
buku -a https://ddg.gg search engine, privacy --title 'DDG' --immutable 1
Note that URL must precede tags.
4. Add a bookmark without a title (works for update too):
buku -a https://ddg.gg search engine, privacy --title
5. Edit and update a bookmark from editor:
buku -w 15012014
This will open the existing bookmark's details in the editor for modifications.
Environment variable EDITOR must be set.
6. Update existing bookmark at index 15012014 with new URL, tags and comments, fetch
title from the web:
buku -u 15012014 --url http://ddg.gg/ --tag web search, utilities -c Private search engine
7. Fetch and update only title for bookmark at 15012014:
buku -u 15012014
8. Update only comment for bookmark at 15012014:
buku -u 15012014 -c this is a new comment
Applies to --url, --title and --tag too.
9. Export bookmarks tagged 'tag 1' or 'tag 2' to HTML and markdown:
buku -e bookmarks.html --tag tag 1, tag 2

buku -u
buku -u --tacit (show only failures and exceptions)
This operation does not modify the indexes, URLs, tags or comments. Only title is
refreshed if fetched title is non-empty.
13. Delete bookmark at index 15012014:
buku -d 15012014
The last index is moved to the deleted index to keep the DB compact.
