approx-gc - garbage-collect the cache of Debian archive files


approx-gc [OPTION]...


approx-gc scans the cache created by approx(8) and finds files that are corrupted or no longer needed. With no options specified, these files are listed on standard output and removed from the cache.

A corrupted file is one whose size or checksum does not match the value specified in the Packages or Sources file.

An unneeded file is one that is not referenced from any distribution's Packages or Sources file.

approx-gc may take several minutes to finish.


-f, --fast
Don't perform checksum validation.
-k, --keep, -s, --simulate
Don't remove files from the cache.
-q, --quiet
Don't print file names.
-v, --verbose
Indicate the reason for removal of each file with a prefix character: `=' for incorrect size, `!' for incorrect checksum, blank for unneeded.


To remove all unneeded or corrupted files from the cache:

approx-gc --quiet

This is run as a weekly cron(8) job.

To list the files that would be removed from the cache, without actually doing so:

approx-gc --keep
