samba winpopup script

[Louis-David Mitterrand]

Hello,

I am trying to build a script to notify all users on a LAN of network
conditions through the winpopup protocol. To get all users connected to
the samba server from which the winpopup messages will be sent I must
parse smbstatus' output:

	Premier      nobody   nogroup  20067   sophia08 (192.168.5.100) Mon Apr  2 17:34:43 2001
	Premier      nobody   nogroup  20079   dev03    (192.168.0.136) Mon Apr  2 17:39:33 2001
	Premier      nobody   nogroup  20124   info09   (192.168.0.221) Mon Apr  2 18:00:01 2001
	Premier      nobody   nogroup   7827   lnc_siege (192.168.0.70) Tue Mar 27 16:54:29 2001
	[etc.]

And invoke:

	% echo $MESSAGE | smbclient -M $MACHINE -I $IP

I started writing a script:

	MESSAGE="test"
	for i in `smbstatus | grep '(\w\+\.\w\+\.\w\+\.\w\+)' `; do
		echo $i | read SHARE USER GROUP MACHINE IP JUNK
		echo $MESSAGE | smbclient -M $MACHINE -I $IP
	done

But $i contains each inidividual element of the smbstatus output, not
each line. How could I capture each line into $i and the read the
elements?

Thanks in advance for your help, cheers,

PS: I'd like the script to be compatible with /bin/sh ideally

Offhand - smbstatus definetely needs "no header" option like many others have.

smbstatus | grep '(\w\+\.\w\+\.\w\+\.\w\+)' | while read SHARE USER GROUP
MACHINE IP JUNK
do
   ... bla bla bla
done

On further consideration the script needs to weed out duplicates (users
that are connected to several samba shares):

(grep '(\w\+\.\w\+\.\w\+\.\w\+)' < smb.status |\
while read SHARE USER GROUP PID MACHINE IP JUNK
do
	IP=${IP%%\)}
	IP=${IP##\(}
	echo $IP $USER $MACHINE
done) | sort | uniq | \
while read IP USER MACHINE
do
	echo $IP $USER $MACHINE
	bla bla bla ...
done
