I start with -w and use strict so I generally catch errors as I go. I use a lot of print statements as I am creating a script to make sure everything is where I expect it to be, and if I am stuck chasing something specific, good old perl -d usually does the trick.

my $a='62696c6c77667269656e6440676d61696c2e636f6d';
while ($a=~m/(^.{2})/s)
{print unpack('A',pack('H*',"$1"));$a=~s/^.{2}//s;}

Kevin, your sig code was nagging me. I was able to shorten it down to this: `perl -e '$a="62696c6c77667269656e6440676d61696c2e636f6d";print unpack("A",pack("H*","$1")) while ($a=~s/(^.{2})//s)'` You don't need both the m// and s///, just one s/// will do. And the block { } notation after the while isn't necessary.	[reply] [d/l]

hmm ... superdoc's version may be shorter or whatever, but it doesn't run on windoze due to a syntax error. Kevin's has the advantage of actually working.	[reply]

Hm. Could be that cmd.exe shell and quoting. Maybe this one will work: `perl -e '$a=qq/447564652c2067657420726964206f662057696e646f 7773/;print (chr hex $1) while ($a=~s/(^.{2})//)'` [download] Or with double-quotes: `perl -e "$a=qq/447564652c2067657420726964206f662057696e646f 7773/;print (chr hex $1) while ($a=~s/(^.{2})//)"` [download] I don't have access to any Windows machine at all to try it on.
