Perl : accept multiple user entered command line arguemnts
I am trying to create a script that will accept multi input from the user (really just me), then execute those command on a remote device.

My question is if the I enter "No" at the confirmation point "Are these statements correct y or n ?", what is the best way to go back and start over ? I have been trying different things with while and until flags but nothing is working.


Code:
#!/usr/bin/perl
use warnings;
use strict;
my @cmdlist;
my $cmd;
system("clear");
print "\nEnter one command per line then press enter.\n";
print "when you are complete entering data, press enter.\n"; 
 while (<>) {
  last if ($_ =~ /^\s*$/); # Exit if just spaces or an enter
  print "You typed: $_";
  push @cmdlist, $_;
 }
#
system("clear");
print "The following is what will be sent to the remote device.\n" ;
 foreach (@cmdlist) {
  do
   print "$_";
  }
#
print "Are these statements correct y or n ?\n" ;
my $ans=<>;
 if ($ans =~ m/n/i) {
  print "No\n"; 
 }

Thanks
