How can I capture the output of remote commands then issue more remote commands?

Question

I am running a script where it login to a server then executes the command "passwd -n 0 -x 99999 -i -1 debug" for removing ageing of the debug user. If the user debug is not present then I want to create the user debug, change the password it, and then execute the above command for ageing.

How can I do?

From perlfunc(1):

          system LIST
               [...]
               The return value is the exit status of the program as returned
               by the "wait" call.  To get the actual exit value, shift right
               by eight (see below).

Therefore:

my $ret = system(qw/passwd -n 0 -x 99999 -i -1 debug/);
if ($ret != 0) {
  # failure handling code here
}
