What Others Think

There's a few things wrong with this. First, it'd be much simpler to search for: [jJ][aA][nN] Next, you're not searching for whole words, so the word "janitor" would be matched. \<[jJ][aA][nN]\> Finally, sed is the wrong tool for the job: grep -iw jan data.txt > jan-only-data.txt -i = case insensitive -w = whole word match
