Need equivalent of command with nmap, awk and grep for Windows machines with PowerShell and/or Perl

  • 772

Please see this thread for reference

How can I scan using nmap and Zenmap all hostnames that begin with a particular string?

One of the answers in the thread above uses the following query (I take no credit at all for the command):

nmap -sL -oG - 192.168.0.0/24 | awk '$3~/^(org/{print $2}' | nmap -iL -`

It scans all nodes for hostnames starting with org and returns a list of matching nodes.

It works great in a Unix/Linux environment, but I need an equivalent for Windows. I'd prefer not to use awk, sed, or grep packages for Windows. I'd like to maintain a standard and use PowerShell and/or Perl.

Is there an equivalent way to construct this query using PowerShell and/or Perl, along with nmap?

    The Nmap parts of that command should work the same. To convert the awk command to Perl, use:

    perl -lane "print $F[1] if $F[2]=~/^\(org/"

    (Because of quoting differences between Windows cmd.exe and most *nix shells, *nix shells should use single quotes instead of double)

    To do the same in PowerShell, this should work (not tested):

    %{ if ($_.Split()[2] -match "^\(org") { $_.Split()[1]; } }
