Re: UNIX 'command' equivalents in Perl

[RMGir]

UNIX	Perl	Origin
cut	split	built-in
if	if, unless	built-in
while	while, for, foreach	built-in

Of course, cut usually winds up being in a complex pipe with sed, sort, and join, so if you see cut in a pipe sequence, odds are you've found a perfect piece of shell script to convert to perl...

And complex conditional or looping structures are much easier in perl than shell (at least to me...)
