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.
