Grep'n more than one string - UNIX for Dummies Questions & Answers

kingdbag · #1 (**permalink**) 10-25-2006

If I want to grep more than 1 string in a bunch of files and I don't want it to be case sensitive how would I do that? This simple thing is freaking me out haha

example:
grep -i rgb cmts hosts.*

rgb and cmts are the two strings im looking for I can't seem to get it to look for both....UGH

'egrep' is your 'freaking' friend:

Code:

egrep -i (rgb|cmts) hosts.*
