.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
|
|
- the \fIcurrent directory\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.
|
|
.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.
|
|
.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.
|
|
.PP
|
|
.IP 8. 4
|
|
\fBSearch\fR works in mysterious ways:
|
|
- Case-insensitive.
|
|
- Matches exact words in URL, title and tags.
|
|
- --sany : match any of the keywords in URL, title or tags.
|
|
- --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 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 \fBunencrypted on creation\fR.
|
|
.PP
|
|
.IP 10. 4
|
|
\fBProxy\fR support: refer to the \fBENVIRONMENT\fR section.
