grep listing filenames without content

Question

How can we list only filenames after searching using grep?

When I use

grep -i -R "search keyword" folder

it'll list all the inline lines of code also.

Answer 1

From grep man page:

-L, --files-without-match Suppress normal output; instead print the name of each input file from which no output would normally have been printed. The scanning will stop on the first match.

-l, --files-with-matches Suppress normal output; instead print the name of each input file from which output would normally have been printed. The scanning will stop on the first match. (-l is specified by POSIX.)

For you, -l option would be helpful.

Answer 2

Use

grep -i -R -l "search keyword" location

to get the list of files which contain the keyword.
