Top Forums Shell Programming and Scripting advantages of Perl ? Post 302128649 by Perderabo on Wednesday 25th of July 2007 11:35:32 PM

There are tasks that are very hard or impossible even with a powerful shell like ksh. Example: unix keeps time internally in seconds since the epoch. What date and time would 1164876000 correspond to? That would be a complex shell script if you had only a Posix shell and Posix utilities to work with. Perl solution:

perl -e 'print scalar localtime(shift),"\n"' 1164876000

Perl can manipulate text quite adroitly but so can Posix shells. I switch to perl when my requirements exceed the power of a shell. Often I use perl to write one-liners as above to assist the shell. While I doubt that you could write a device driver in perl, perl approaches c in power.
