I'm running a script to bring down the logical ip address . But if the system doesnt have that logical ip addresss then i get the following error print on terminal -
SIOCSIFFLAGS: Cannot assign requested address
I just want to know whether there is a way to suppress that print so that user is not aware of that.
May be some check before pulling down the logical ip.
the script file content is -
ifconfig eth0:1 down
is there any syntax by which i can check whether eth0:1 is up or not .
My purpose is not to show the user that error msg and i wanna do it from the script file itself not modify some system files as i wouldnt know on which (linux) system the user will be excuting that script.
