If you don't want the play by play report of what will be kept and what will be removed, delete the lines in blue above. Once you have convinced yourself that it will remove the files you want removed, delete the echo in red above.

Enjoy...
Brilliant, I tested it on CentOS 6 bash, it works perfectly. The complexity is beyond my imagination.

Thank you so much Don, you are superb :-).

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. SEE ALSO
