Directory Purge Utility

On Athena5 (aka. p5) the script /local/opt/purgedir/purgedir may be used to report and/or delete files older than a specified threshold. The full manpage is listed below, and may be seen via "purgedir --man", but the general usage is "purgedir --age=days --warn --delete dir ..." This script can be run "by-hand" as needed, or could be set up to run as a cron job via a cron.d file similar to below:

/etc/cron.d/purgedir:

# 3AM Mon: Report impending deletions
0 3 * * 1 root /local/opt/purgedir/purgedir --age=14 --warn /psfs/fc-scr-1/scratch1/*
0 3 * * 1 root /local/opt/purgedir/purgedir --age=14 --warn /psfs/fc-scr-2/scratch2/*

# 3AM Tue: Do deletions one day later
0 3 * * 2 root /local/opt/purgedir/purgedir --age=15 --warn --delete /psfs/fc-scr-1/scratch1/*
0 3 * * 2 root /local/opt/purgedir/purgedir --age=15 --warn --delete /psfs/fc-scr-2/scratch2/*

[edit] Purgedir Manpage

NAME
       purgedir - report and purge old files

SYNOPSIS
       purgedir [--warn] [--delete] --age=days dir ...

DESCRIPTION
       purgedir walks recursively through a given list of directories search-
       ing for and optionally deleting any regular files older than a speci-
       fied threshold age.  If desired, a report of the identified "old" files
       for each directory will be written to a file with the same name plus a
       .purge suffix.

       Note that directories, symlinks and special files are neither reported
       nor deleted.

OPTIONS
       purgedir supports the following command-line options:

       -a, --age=days  (REQUIRED)
               Sets the threshold for what is to be considered and "old" file.
               The threshold is set to be days*24hr before the start of script
               execution.

       -w, --warn
               For each directory processed, a report file named dir.purge is
               created containing the list of "old" files to be deleted.

       --delete
               For each directory processed, purgedir will actually attempt to
               delete the "old" files.  Without this option, no deletions are
               performed.

       -q, --quiet
               Sets the verbosity level to âquietâ.

       -v, --verbose
               Increases the verbosity level.

       -d, --debug[=n]
               Increases [sets] the debug level.

       -V, --version
               Prints the program version and exits.

       --help  Prints a brief help message and exits.

       --man   Prints the full manual page and exits.
