The ".NetValue Series" of Mount/\Commands provide several variations of
comma-separated lists that will do what you need. In particular, the
command ".NetIPMacs" provides a list in the format


The syntax for this command is simply


That one-word command CONSISTENTLY provides this list under NT/2K/XP/K3.

See (http://TheSystemGuard.com/MtCmds/NetValue) for more info.

very welcome.

The essence of the .NetIPMacs command is to reformat the output of Net View
for computernames only, send it to Nbtstat to pick up the MAC addresses, and
then combine the first two with ping to get the IP Addresses.

By structuring the code into a "single line command" or Mount/\Command, and
then giving it a "sounds like what it does" name (i.e., NetIPMacs), your
scripts will be self-documenting. For more info on MountCommands, see


1. .Mount/\Commands are constructed using ONLY builtin
commands common to all four platforms (NT/2K/XP/K3).
2. .M/\C's are NOT case sensitive. Mixed case is used
for Visual Clarity only.
3. ntlib.cmd provides over 100 resources to assist with
writing and documenting cross-platform scripts,
including 57 fully functional .Mt/\Cmds.
