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

              Configuration file for approx and related programs.
