Re^2: getting a while loop to terminate

Nope :) See What is true and false in Perl?, Tutorial::What is true and false?, True or False? A Quick Reference Guide

$ perl -le " die 666 if q/0/ "

$ perl -le " die 666 if $what = q/0/ "

$ perl -le " die 666 if $what = q/1/ "
666 at -e line 1.

$ perl -le " die 666 if $what = q/0E0/ "
666 at -e line 1.

$ perl -le " die 666 if $what = q/0 but true/ "
666 at -e line 1.

I guess I don't follow you here: `$ perl -le " die 666 if q/0/ " $ perl -le " die 666 if $what = q/0/ " syntax error at -e line 1, near "if =" Execution of -e aborted due to compilation errors. $` [download]	[reply] [d/l]

My shell doesn't interpolate $what, as you can see from the session I posted, use single quotes if your shell interpolates doubles Or you could even omit `$what =` Whether it is assigned to a variable or not , '0' is always false	[reply] [d/l]
