Hi

I wrote a little script which collects by each execution some information from /proc-filesystem on GNU/Linux and saves them in /var/script/proc/tmp to the files fs, kernel and net.

After the script ran without errors the directory /var/script/proc/tmp is moved (with File::Copy::move()) to /var/script/proc/$year$jday.$hour$min.$sec.

This way I get some kind of history and I may reconstruct what changed between two script pass throughs.

The problem is after 100 exections in /var/script/proc/ there are also 100 directories. But I only need the data of the $n last executions, e.g $n=10.

I'd like to add a purge() function which gets called at the end of the script and only keeps the $n newest directories in /var/script/proc/.

How can I do this? Is there a module which does this?

Thanks, Kathy
