In general, just use the "right tool" for the job .. where that depends on the specific task and your knowledge/speed/ability in each, and relevant to that task..

BUT, that doesn't mean one or the other -- use the power of both at the same time!! the perl -x (see perlrun) makes this possible (sort of a trivial example, but hopefully shows the potential):

#!/bin/bash

  logrotate ..... # rotate out /data/file.txt
  perl -x $0 $@ > /data/file.txt 2>&1
  mail -s "file.txt" me@example.com < /data/file.txt
  echo "Job done. Errors:"
  grep ERROR /data/file.txt

exit
#######
#!/usr/bin/perl

# do whatever perl-friendly tasks -- process some files, do calculatio
+ns, call CPAN modules for heavy lifting, whatever.
