Script to shutdown XP clients

My staff seem to have a habit of leaving thier PCs on over night so I need to write a short script to shutdown any XP clients logged into the local samba domain that I can run as a cron job at a set time.

I can list the connected clients and their IP addresses with:
Code:
$ smbstatus -b

Samba version 3.4.9
PID     Username      Group         Machine
-------------------------------------------------------------------
5190      user1     __USERS__     machine1  (10.0.0.10)
26799     user2    __USERS__     machine2  (10.0.0.6)
4173      user3        __USERS__     machine3   (10.0.0.11)

And I can shutdown individual clients with:
Code:
$ net rpc SHUTDOWN -C "shutting down" -f -I 10.0.0.6 -U adminuser%password

What I need the code to do is parse the result of the smbstatus command and pass the IP addresses to the net rpc command for as main IP addresses found.

Thanks

Code:
smbstatus -b | awk -F"[()]" '{ print $2 }' | while read IPADDRESS
do
        echo "IP address is $IPADDRESS"
done

Thanks Corona;
So my script will look like:
Code:
#!/bin/bash
smbstatus -b | awk -F"[()]" '{ print $2 }' | while read IPADDRESS 
do
    net rpc SHUTDOWN -C "shutting down" -f -I $IPADDRESS -U adminuser%password
done

Will this loop for as many IP addresses found or just the first one?

Thanks

It ought to loop through all of them.

I'd try what I actually posted first, before you get too ahead of yourself. If your version of awk doesn't support regexes in -F it may not work.

OK, here's the output:
Code:
~$ smbstatus -b | awk -F"[()]" '{ print $2 }' | while read IPADDRESS
> do
>         echo "IP address is $IPADDRESS"
> done
IP address is
IP address is
IP address is
IP address is
IP address is 10.0.0.10
IP address is 10.0.0.11

I guess I need to start on the 5th line of the output from smbstatus -b command? I am using ubuntu10.04

I think I can fix that:

Code:
smbstatus -b | awk -F"[()]" '$2 { print $2 }' | while read IPADDRESS
do
        echo "IP address is $IPADDRESS"
done

That should make awk only print lines when $2 (the second token) isn't blank.
