Question

Red Hat Enterprise Linux Server release 5.4 (Tikanga)
2.6.18-164.el5

I am trying to use the watch command combined with the netstat to see the 2 programs using certain ports.

However, with the command I using below doesn’t work for both words:

watch -n1 "netstat -upnlt | grep gateway\|MultiMedia"

Is this the correct way to grep for both program names.

If I use one its ok, but both together doesn’t work.

Answer 1

For the grep you need:

"grep gateway\|MultiMedia"

So perhaps try:

watch -n1 'netstat -upnlt | grep "gateway\|MultiMedia"'
