Usage:
- apt-cache [options] command
- apt-cache [options] show pkg1 [pkg2 …]
apt-cache queries and displays available information about installed and installable packages. It works exclusively on the data acquired into the local cache via the ‘update’ command of e.g. apt-get. The displayed information may therefore be outdated if the last update was too long ago,but in exchange apt-cache works independently of the availability of the configured sources (e.g. offline).
Most used commands:
- showsrc - Show source records
- search - Search the package list for a regex pattern
- depends - Show raw dependency information for a package
- rdepends - Show reverse dependency information for a package
- pkgnames - List the names of all packages in the system
- policy - Show policy settings
