USES FOR AWK

If you have a server with alot of filesystems on it (oracle/SAP environments) then this little awk command can come in useful. It can obviously be used in many other situations also. In this example, the file structure is /oracle/PRD/xxxx.

awk '/PRD/{ print "umount " $3 }' /etc/vfstab | /sbin/sh

If you run it without piping it to 'sh', then it will show you what the command will do. You can replace the 'umount' with whatever command you like. It's a quick and easy though.
