Re: Re: Script to change $ENV{PATH}

[TheHobbit]

Argh.... I'm stupid today:) There is a big mistake in my post...

The component order in PATH-like variables is important, sometimes very important, and my munch.pl script mess it up. This version of munch.it don't has this pitfall:

#!/usr/bin/perl -w
use strict;
my @comp = split /:/,shift;
my %saw = ();
my @out = ();
for (@comp) {
  push @out,$_ unless $saw{$_}++;
}
print join ":",@out;

Now I may gonna hide in the monastery cellar...
