-
additional help
- tag
-
(not implemented anymore)
- cat (grep)
-
output the lines of the full package tag database that
match the given tag expression. A tag expression
(given as a single argument) is an arbitrarily complex
binary expression of tag names. For example:
role::program && ((use::editing || use::viewing) &&
!works-with::text)
- check
-
Check that all the tags in the given tagged collection
are present in the tag vocabulary. Checks the main
database if no file is specified
- diff (mkpatch)
-
Create a tag patch between the current tag database
and the tag collection [filename]. Standard input is
used if filename is not specified
- search (dumpavail)
-
Output the packages matching the given tag expression
- show
-
(deprecated) mostly the same as apt-cache show
<pkgnames>
- submit
-
(no longer supported) see
https://debtags.debian.org/api/patch for patch submit.
- tagcat
-
Output the tag vocabulary
- tagshow
-
Show the vocabulary information about a tag
- tagsearch
-
Show a summary of all tags whose data contains the
given strings
- update
-
Updates the package tag database (requires root)
Collect package tag data from apt cache, regenerate
the debtags tag database and main index. It needs to
be run as root
- vocfilter
-
Filter out the tags that are not found in the given
vocabulary file
debtags manages package tag data in a debian system and performs basic
queries on it.
debtags can be used to perform basic queries on the Debtags system: the
vocabulary can be queried with the tagshow and tagsearch commands;
a package tag database can be checked against the vocabulary with the
check command; the whole collection can be copied to standard output to
be processed with tagcoll or other tools by the cat command;
packages can be searched by tags using the grep command. Finally, tags
can be listed with tag ls, edited with the tag add and tag
rm, and submitted to the Debtags database with submit.
The update command can be used to download extra tags as listed in
/etc/debtags/sources.list: see the contents of that file for more
information.
FILES
- /var/lib/debtags/vocabulary
-
The normative tag vocabulary
- /var/lib/debtags/package-tags
-
The system package tags database, only kept as an easily parsable reference.
In the same directory there is a the binary index with the same content, used
by applications for fast access.
- /etc/debtags/sources.list
-
The list of sources to build the package tags database from
EXAMPLES
Here are some example invocations of debtags:
# Update the package tag database
debtags update
# Show apt-cache information about the mutt package,
# adding tag information
debtags show mutt
# Search the tag vocabulary for mail-related tags
debtags tagsearch mail
# Output a list of all packages which can edit raster images, excluding
# shared libraries and dummy packages
debtags search "use::editing && works-with::image:raster && \
! (role::shared-lib || role::dummy)"
# Show all mail clients
debtags search 'works-with::mail && network::client'
# Output the collection of all mail clients, ready to be reprocessed via
# tagcoll
debtags grep 'works-with::mail && network::client'
# Produce an easily navigable hierarchy with the collection data
debtags cat | tagcoll hierarchy
# Produce a local tag patch
debtags cat > work-tags
...edit work-tags...
debtags diff work-tags > my-tagpatch
# Submit the patch
debtags submit my-tagpatch
# Edit the tags of a package (the patch will be stored in ~/.debtags/patch)
# then send your changes
debtags tag add debtags implemented-in::c++ interface::commandline
debtags tag rm debtags devel::buildtools
debtags submit
