approx-gc
APPROX-GC(8) System Manager's Manual APPROX-GC(8)
NAME
approx-gc - garbage-collect the cache of Debian archive files
SYNOPSIS
approx-gc [OPTION]...
DESCRIPTION
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.
OPTIONS
-c file, --config file
Specify an additional configuration file. May be used multiple times.
-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
Print the reason for removal of each file.
EXAMPLES
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
FILES
/etc/approx/approx.conf
Configuration file for approx and related programs.
/var/cache/approx
Default cache directory for archive files.
