Re: how to ignore regex in input to getopt::Long

Couple of things 1. you have to escape the exclamation mark in the command line i.e. ./scriptname -a sdf\!sdf -b gwerwer 2. following is the code to capture $1 and $2, assuming that you are capturing the value in switch a (-a) in $data

if($data =~ m/(.+)?\!(.+)/)
{
    print "first: $1  ,   next:$2  \n";
}

Hi, thanks for replying. However, I am trying to have it so that people do not have to escape anything on command line.. is this not possible due to shell interpretation before perl?	[reply]

It depends on your OS/shell. In unix-type shells, `!` must be escaped because of its special meaning as a command history/substitution character. I just verified this on 3 shells: sh, bash and tcsh. However, at a Windows DOS prompt, it is not necessary to escape the `!`.	[reply] [d/l] [select]

Then don't use a character that has a special meaning for many popular shells. What about ":"?	[reply]
