Delete all files that haven't been accessed in 1.5 days in /dir and /ect:

    find2perl /dir /ect -eval '-A > 1.5 and unlink' | perl

And completely unnecessary, given the above perl command-line. :-)

The output of this find2perl run is 17 lines of Perl, by the way.

Perl is your friend.  Use Perl.
