opposite of grep

3saul · 02-23-2006, 11:00 PM

I'm wanting to match line if it doesn't equal something...

For example

ls | grep ab

Would match any file that has 'ab' in it and return it. I'm wanting to exclude any file that has a particular phrase..

Thanks

ls |grep -v ab
-v switch is what you want

and if i wanted to exclude more than one word?

ie: top |grep -v daemon +conky +firefox (excuse my googlystuff)

Hi,

You can use egrep for that: ls | egrep -v "daemon|conky|firefox"

This will exclude daemon, conky and firefox from the ls listing.

Hope this helps.

grep -E (aka egrep) - use regex rather than googlystuff.

Code:

top  -b -n 1 | grep -Ev "(daemon|conky|firefox)"

Too late - hi druuna

Or do it the uneffcient way.

$ ls | grep -v "not_this" | grep -v "or_this" | grep -v "and_not_this_too"
