grep from a text file of keywords?

Question

Is it possible to use grep with a text file of keywords?

For example instead of grep -r "keyword" directory/ Something like grep -r keywordList.txt includes/

where keywordList.txt is full of a bunch of keywords?

fgrep -rf keywords.list includes/

keywords.list must be one keyword per line, with no extra whitespace and no regular expressions.

	On most systems fgrep just maps directly to "grep -F". Depending on your work flow, knowing that may be more useful in the long run. – Scott Pack Jan 31 '10 at 2:15
