Re^2: How do I get different files into an array

    Thank you james28909,

    That worked perfectly!, The script stops and says su: incorrect password, these are Linux boxes at when it sends the passwords during the expect/send of su - root.

    Is it because I will have to escape the special characters when it starts to send the strings with special characters, I did not have to do this with Solaris boxes?

    Is there a way to just alway ignore special characters only during the send part of expect?

    Hello james28909,

    Thank you for your suggestion I put it in my script but I am missing something. 

    "my" variable $file masks earlier declaration in same scope at test-a-
+filehandle.pl line 17.
syntax error at test-a-filehandle.pl line 19, near "<$file> {"
Execution of test-a-filehandle.pl aborted due to compilation errors.

    This is how it is placed in my script. 

    #!/usr/bin/perl -w

my $header = "\r\n\r\n======= system =======\r\n";

my $file = "/home/amagana/scripts/lists/list_xx";



my @servers;

open (my $file, '<', $ARGV[0]) or die! $!;

while(<$file> {
     push (@servers, $_); #push each line of the file to array
     }

print "$_\n" for(@servers);

for my $server (@servers) {
# do your thing with $server

    change_password($server);

 }


sub change_password {

      my $system = shift;
      my $ssh = Expect->new('ssh amagana@' . $system);

my $my_header = $header;
$my_header =~ s/system/$system/;
