Newbie No output from shell script

nl1at · 04-03-2006, 02:46 PM

Im very new to shell scripting.
I´ve made a shell script to check my isp link .

Code:

#!/bin/sh
. /etc/dhcpdpc/dhcpcd-eth0.info

if ! ping -qnc 1 $GATEWAY ; then
/usr/sbin/renet
fi

But i dont want the output from the ping cmd.
How can i do just that?
And how do i check eth0 is up?
And i want to check it every 5 minutes , what the best way to do that?

For the first part, you can divert ping's standard output to /dev/null with:

Code:

ping -qnc 1 $GATEWAY >/dev/null

For the second part have a look at crontab's man page. From memory, the crontab line will be something like:

Code:

*/5 * * * * /path/to/your/script
