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.

       -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 [...]
              Search  bookmarks by a tag. List all tags alphabetically, if no arguments. The index of a tag from
              the tag list can be used to search all bookmarks having the tag. Note that multiple indices and/or
              ranges do not work with this key.

       o id|range [...]
              Browse bookmarks by indices and/or ranges.

       p id|range [...]
              Print bookmarks by indices and/or ranges.

       g [taglist id|range ...] [>>|>|<<] record id|range [...]
              Append,  set,  remove  specific  or  all  tags by indices and/or ranges to bookmark indices and/or
              ranges (see EXAMPLES section below).

       w [editor|id]
              Edit and add or update a bookmark.

       c id   Copy url at search result index to clipboard.

       O      Toggles ignore text-based browsers. If enabled, tries to open urls in a GUI based browser (even if
              BROWSER is set).

       ?      Show help on prompt keys.

       q, ^D, double Enter
              Exit buku.

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                                       │

       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 -e bookmarks.md --tag tag 1, tag 2
              buku -e bookmarks.db --tag tag 1, tag 2

           All bookmarks are exported if --tag is not specified.

       10. Import bookmarks from HTML and markdown:

              buku -i bookmarks.html
              buku -i bookmarks.md
              buku -i bookmarks.db

       11. Delete only comment for bookmark at 15012014:

              buku -u 15012014 -c

           Applies to --title and --tag too. URL cannot be deleted without deleting the bookmark.

       12. Update or refresh full DB with page titles from the web:

              buku -u
              buku -u --tacit (show only failures and exceptions)

       14. Delete all bookmarks:

              buku -d

       15. Delete a range or list of bookmarks:

              buku -d 100-200

       21. Search  for  bookmarks matching any of the keywords 'hello' or 'world', excluding the keywords 'real'
           and 'life', matching both the tags 'kernel' and 'debugging', but excluding the tags  'general  kernel
           concepts' and 'books':

              buku hello world --exclude real life --stag 'kernel + debugging - general kernel concepts, books'

       22. List all unique tags alphabetically:

              buku --stag
