( #3333=superdoc: print w/replies, xml ) Need Help??
The code somebody else wrote cleans out old files, but leaves the directories behind. This cleans up the directories.

#!/usr/bin/perl use strict; use warnings; chomp(my @list = `du -kh /mnt/edi/si51/documents`); my $dltd = 0; foreach my $line (@list) { my ($size,$path) = split /\t/, $line; $size =~ s/\D//g; if ($size == 0) { rmdir $path && $dltd++ } } printf "%d directories deleted.\n",$dltd;

UPDATE: There are several things that were in an earlier version of this script that didn't make the second cut, but only because I got lazy. My original got deleted somehow, and I had foolishly not kept a copy, so I wrote the above quickly.

The directory structure is documents/4digityear/abbreviatedcardinalmonth/2digitday/hour/minute. At first I restricted deletions to directories above some number of days old, but rmdir updates the directory time information, meaning a directory that was now empty because all its empty constituent directories were gone looked like it was brand new. This made it useless to run consecutively. I came up with a calculation that used the directory tree to come up with the age, and that worked. I just didn't bother with it when I rewrote the script this time. Some of the alternate solutions don't have that limitation.

But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us. Romans 5:8 (NASB)
