.SH OPERATIONAL NOTES
.PP
.IP 1. 4
The database file is stored in:
  - \fI$XDG_DATA_HOME/buku/bookmarks.db\fR, if XDG_DATA_HOME is defined (first preference) or
  - \fI$HOME/.local/share/buku/bookmarks.db\fR, if HOME is defined (second preference) or
  - \fI$PWD\fR
.PP
.IP 2. 4
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 ('/").
.PP
.IP 3. 4
URLs are unique in DB. The same URL cannot be added twice.
.PP
.IP 4. 4
Bookmarks with immutable titles are listed with bold '(L)' after the URL.
.PP
.IP 5. 4
\fBTags\fR:
  - 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.
  - 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 --\fIfixtags\fR 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 \fBbuku --fixtags\fR once.
.PP
.IP 6. 4
\fBUpdate\fR 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.
.PP
.IP 7. 4
\fBDelete\fR 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.
.PP
.IP 8. 4
\fBSearch\fR 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 \fBsubstrings\fR (`match` matches `rematched`) in URL, title and tags.
  - --sreg : match a regular expression (ignores --deep).
  - --stag : search bookmarks by a tag, or list all tags alphabetically with usage count (if no arguments).
  - Search results are indexed serially. This index is different from actual database index of a bookmark record which is shown in bold within '[]' after the URL.
.PP
.IP 9. 4
\fBEncryption\fR is optional and manual. AES256 algorithm is used. To use encryption, the database file should be unlocked (-k) before using \fBbuku\fR 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 \fBunencrypted on creation\fR.
.PP
.IP 10. 4
\fBEditor\fR 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.
.PP
.IP 11. 4
\fBProxy\fR support: please refer to the \fBENVIRONMENT\fR section.
.SH GENERAL OPTIONS

before adding it. To edit and update an existing bookmark, the
.I index
should be passed. However, in this case the environment variable EDITOR must be set.
.TP
.BI \-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.

Show program version and exit.
.TP
.BI \-h " " \--help
Show program help and exit.
.SH EDIT OPTIONS

.SH SEARCH OPTIONS
.TP
.BI \-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 in bold within '[]' after the URL.
.br
This is the default search option for positional arguments if no other search option is specified.
.TP
.BI \-S " " \--sall " keyword [...]"
Search bookmarks with ALL keywords in URL, title or tags and show the results. Behaviour same as --sany.
.br
Special keywords:
