Content search.

$ ff() { local IFS=’|'; grep -rinE “$*” . ; }

Grep will read the contents of each file in PWD and will use the REs $1 $2 … $n to match the contents.

In case of match, grep will print the appropriate file, line number and the matching line.

It’s just easier to write

ff word1 word2 word3

Instead of

grep -rinE ‘word1|word2|word3′ .
