Hey Monks. I found an anomaly, at least I think it is. Consider the following code:
#!/usr/bin/perl use strict; use warnings; my $str = '/path/to/f(il)e'; (my $name = $str) =~ s{.*/}{}; # basename (my $path = $str) =~ s{$name}{}; print " str = $str\n"; print "name = $name\n"; print "(unescaped) path = $path\n"; ($path = $str) =~ s{\Q$name\E}{}; print "(escaped) path = $path\n";

That produces the following output:

str = /path/to/f(il)e name = f(il)e (unescaped) path = /path/to/f(il)e (escaped) path = /path/to/

The first substitute (basename) worked. The 2nd, the one that was supposed to isolate the path part of the string does NOT work because there are parentheses in $name.

I worked around it with the \Q...\E trick, but I want to know why parens in the variable screwed up one substitute but not the other one
