in reply to Understanding the Schwartzian transform.

The map builds a list of anonymous arrays, or better, it builds a list of tuples file name, file age. Sort then sorts the tuples based on their second element (the age), the final map throws the age away and only leaves the names.

[Lady_Aleena]: And the env variable $HOME doesn't work either. !@#$
[shmem]: no, that's a shell feature. Use $ENV{HOME}
[marioroy]: my $ans = qx{ find \$HOME -name "*.pl" -exec ls -l {} \\; };
[marioroy]: must backslash $ inside qx
[Lady_Aleena]: I haven't written perl for a while, I've been trying to do things at the command line. I'm having to relearn a lot.
[marioroy]: LA can you post the qx find again
[Lady_Aleena]: Things I would have written a script for while I was on Windows, I can run simply on the command line.
[Lady_Aleena]: marioroy, my @music_times = qx(find ~/Music/Albums/ -type f -iname '*.mp3' -exec mp3info -p "%S\n" {} \;); #unfixed
shmem doesn't have mp3info, but mp3info2 - which is a perl script ;-)
