That might be impossible to do on a Unix system, because Unix does not keep track of creation times of file or directories. "Creation time" is ambiguous. Assuming that 'foo' exists, and 'bar' doesn't, does "mv foo bar" create bar?

But assuming you know the directories to search by some divine means, no need for Perl. Something like the following will do:

$ find dir1 dir2 dir2 -name '*.out' \
                  '!' -exec grep -q error {} ';' \
                      -exec sh -c 'echo "Whatever" | mail you@there.fo
+o' ';'
