Question

I want to do a grep in bash on a folder searching for the term foobar. I then want to output all of the matches along w/ the filename and line number where the occurrences were found. Is this possible?

I need the output to look like:

{{filename}}:{{line_number}} - {{matched_text}}

Answer 1

grep -nrH 'regex' /dir/

-H is the option that adds filenames, -n adds line numbers, -r is recursive

I get filenames even without the -H unless there’s only one file.

Add -i for case-insensitive

Add -E for extended regular expressions
