- apt-cache - Manages the cache file.
+ apt-cache - Manages the cache files
- This program should eventually handle both low and high level
- manipulation of the cache file. Depending how far things go it
- might get quite a sophisticated UI.
-
- Currently the command line is as follows:
- apt-cache add cache file1:dist:ver file2:dist:ver ...
- ie:
- apt-cache add ./cache Pacakges:hamm:1.0
-
- A usefull feature is 'upgradable' ie
- apt-cache upgradable ./cache
- will list .debs that should be installed to make all packages the latest
- version.
+ apt-cache provides some functions fo manipulating the cache files.
+ It uses the command line interface common to all the APT tools. The
+ only really usefull function right now is dumpavail which is used
+ by the dselect method. Everything else is meant as a debug aide.
Returns 100 on failure, 0 on success.
