You can do like so:

use warnings;
use strict;

  for my $cmd(qw(ls ipconfig)){
     system("$cmd");
  }

2. "..When I run the script below, it only picks the first commands.."
   
Reason and Answer:
"..The "exec" function executes a system command *and never returns*; use "system" instead of "exec" if you want it to return...."
Check also exec and system

3. I used ipconfig instead of the OP ifconfig because I tested this on window OS.
   

Hello Daral, and welcome to the Monastery!

As 2teez explained, you can use system to run an external command from within a Perl script. But note that system returns the command’s exit status, not its output. If you want to capture the command’s output, use backticks (or the equivalent qx operator):

#! perl
use strict;
use warnings;

my $ls = `ls`;
print "Output from ls:\n\n", $ls, "\n";

my $con = `ipconfig`;
print "Output from ipconfig:\n\n", $con, "\n";

Update: To capture both the output and the exit status, use the module Capture::Tiny.

Hope that helps,

$? returns the result code from the last system() call or backtick operation, I believe, so you can both capture output and process result codes.

Example:

#!/bin/perl
# first command deliberately generates an error....
print `rubbish`;
print "Rubbish Result: $?\n";
# this command should succeed
print "ls Output:\n";
print `ls -l`;
print "ls Result: $?\n";

Output:

Rubbish Result: -1
ls Output:
total 10
-rw-r--r-- 1 Userid Domain Users 1242 Oct 30 10:04 1.txt
-rw-r--r-- 1 Userid Domain Users 1531 Oct 30 10:04 2.txt

-rwxr-xr-x 1 Userid Domain Users  108 Oct 31 14:21 var.pl
ls Result: 0

Note the first output of $? is -1 (an error), whilst the second is 0 (success)
