Here is a combo of debian and general unix solutions:
[EMAIL PROTECTED](p2):bhmit1$ more bin/ip
grep IPADDR /etc/dhcpc/hostinfo-eth0 | cut -f2 -d=
I use this to print out just the ip. In my /etc/init.d/dhcpc:
start-stop-daemon --start --verbose --exec $DAEMON -- -c /root/bin/??
This will run the /root/bin/?? command after dhcp has got it's ip address:
(from the man page)
OPTIONS
-c filename
Specifies the command file which is invoked when
dhcpcd successfully gets an IP address.
Also, with your script, busy waits are never a good programming practice.
I'd put a 5 second sleep command in the loop and add a counter. When the
counter is at 10, 50 seconds have gone by.
HTH,
