`perl -n` wraps code in an awk-alike start and finish stanza. `perl -p` wraps code in a sed-alike start and finish stanza.

  So, basically, if I understand, Perl has both awk and sed built in.

    Yes, as per what I read long ago, Larry Wall created Perl as a sort of superset of parts of awk, sed, shell and C (maybe not shell).

      absolutely shell. Perl acts as glue between multiple processes very nicely. $foo = `foo_command`; is great. Opening named pipes. Python is more awkward because it's less like shell.

        Thanks, didn't know that about Perl.
