NAME

ept-cache - High-level tool to access package information

SYNOPSIS

ept-cache [options] <command> [options and arguments]

DESCRIPTION

ept-cache is a high-level tool to access package information.

It can currently search and display data from four sources: the APT database, the Debtags tag information, Popcon package scores and a fast Xapian-based full text index on package descriptions.

If the Xapian data source is enabled, output results are by default sorted by relevance order, with the best results first. If you are seeing strange results in the output, rerun the search with the --full switch and look at the Search-Score headers.

COMMANDS

ept-cache 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.

show <pkg>

show informations about a package, like apt-cache show does, but adds new fields with all available extra metadata

search [keywords]

output the names and descriptions of the packages that match the given tag expression

dumpavail [keywords]

output the full package database, with all extra metadata

reindex

updates the various indexes managed by libept (requires root).
It needs to be run as root

info

show information about the data providers.

related [pkgnames]

Show packages similar to the given ones. Package similarity is computed by how many common elements there are in their descriptions and their tags
