Hello all,

The code below is intended to change the prompt color in bash to red. 
#!/usr/bin/perl

use warnings;
use strict;
use IPC::Open3;

$|=1;

# set \*ERR to 0 to send STDERR to STDOUT
my $pid=open3 (\*IN, \*OUT , 0, '/bin/bash' );

my $cmd = qq( export PS1="\e[0;31m[\u@\h \W]$ \e[m " );
print IN "$cmd\n";              # Send cmd to bash.

my $result = <OUT>;
print $result;

Below is the output of the script. 
Unrecognized escape \h passed through at 11.pl line 12.
Unrecognized escape \W passed through at 11.pl line 12.
Use of uninitialized value in concatenation (.) or string at 11.pl lin
+e 12.

Line 12 is the bash command to change the prompt to red. Also, it is hanging after I ran the script. What am I doing wrong here??
