you can use,
system() command for executes the system commands
you can use print command insted of `echo` for write expres/values
in perl.

I try to write a simple script maybe this will help you Smilie

Code:
!#/usr/bin/perl -w
print "what is your fav shell? ";
$shell = <STDIN>;
print "Execute a new $shell (y/n) ? ";
$choice = <STDIN>;
if ($choice eq "y\n")
{ print "Executing new shell\n"; system("$shell"); }
elsif ($choice eq "n\n")
{ print "Exiting\n"; }
 
$write="perl script completed!!";
system ("echo $write");
 
$echo = `echo $write`;
print $echo;


regards
