NAME
debtags - Command line interface to access and manipulate Debian Package TagsSYNOPSIS
debtags [options] <command> [options and arguments]DESCRIPTION
debtags manages package tag data in a debian system and performs basic queries on it.Package data are activated or updated in the system using the debtags update command; that must be run by root. Tag data are pulled from a variety of sources listed in /etc/debtags/sources.list and merged together.
Recently, a basic version of the tag data is also present in the APT database. It is a very useful resource for applications that are not using debtags-specific functions (such as apt-cache or grep-dctrl), but it does not support local changes or merging from different sources.
debtags itself can also 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; packages related to a given one (or group) can be shown with the related 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.
COMMANDS
debtags accepts a non-switch argument, that indicates what is the operation that should be performed:- help [command]
With no arguments, print a summary of available commands. If given a command name as argument, print detailed informations about that command.- update
Collect package tag data from the sources listed in /etc/debtags/sources.list, then regenerate the debtags tag database and main index.
It needs to be run as root- selfcheck
perform a series of internal self checks using the current tag data- check <file>
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- tagcat
output the tag vocabulary- tagshow
show the vocabulary informations about a tag- tagsearch <string [string [string ...]]>
show a summary of all tags whose data contains the given strings- show <pkg>
show informations about a package, like apt-cache show does, but adding the tag informations from the debtags index- related <pkg1[,pkg2[,pkg3...]]>
Output a list of the packages that are related to the given package or list of packages. If more than one package are to be specified, separate them with commas.
The --distance option can be used to control how closely related the output packages should be from the package(s) specified.- cat
output the full package tag database- dumpavail [tag expression]
output the full package database- search <tag expression>
output the names and descriptions of the packages that match the given tag expression- grep <tag expression>
output the lines of the full package tag database that match the given tag expression- install <tag expression>
Invokes apt-get install with the names of the packages matched by the given tag expression. If you want to see what packages would be installed you can use debtags search, as debtags install just calls apt-get install on all the results of an equivalent debtags search. Please note that debtags install is just a prototype feature useful for experimenting in some environments like Custom Debian Distributions. For this reason it is suggested that you use debtags just as a way to find packages, and proper package managers as the way to install them- diff or mkpatch [filename]
create a tag patch between the current tag database and the tag collection [filename]. Standard input is used if filename is not specified- maintainers
create a tagged collection of maintainers and the tags of the packages they maintain- tag {add|rm|ls} <package> [tags...]
General manipulation of tags, useful for automation in scripts.
It can be used in three ways:
tag add <package> <tags...> will add the tags to the given package
tag rm <package> <tags...> will remove the tags from the given package
tag ls <package> will output the names of the tags of the given package- submit [patch]
mail the given patch file to the central tag repository.If [patch] is omitted, mail the local tag modifications.- todo
print a list of the installed packages that are not yet tagged- score
score uninstalled packages according to how often their tags appear in the packages that are installed already- stats
print statistics about Debtags- smartsearch <word [word1 [+tag [-tag1 ...]]]>
Perform a keyword search integrated with related packages.
A + prefix indicates a wanted tag. A - prefix indicates an unwanted tag. Other words indicate keywords to search.
Remember to use '--' before unwanted tags to avoid having them interpreted as command line switches.- vocfilter tagfile
filter out the tags that are not found in the given vocabulary file
