How can I use grep to show just filenames on Linux?
The standard option
grep -l (that is a lowercase L) could do this.
From the Unix standard:
(The letter ell.) Write only the names of files containing selected
lines to standard output. Pathnames are written once per file searched.
If the standard input is searched, a pathname of (standard input) will
be written, in the POSIX locale. In other locales, standard input may be
replaced by something more appropriate in those locales.
You also do not need
-H in this case.
How can I grep for a filename instead of the contents of a file?
You need to use
find instead of
grep in this case.
You can also use
find in combination with
$ find | grep "f[[:alnum:]]\.frm"
Show unique filename only on command grep result
$ grep ./ -re "Hello"
$ grep ./ -re "Hello" -l
From the manual:
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.
grep output to show only matching file
(That's a lowercase L)
how to display file name during grep
I'm sure this has been on here before, but you just need to give it a second file name
for file in *.py;
do grep -n --color 'main' $file /dev/null;
unix command line ...how to grep and show only file names that contain a string?
-l flag (or, in both BSD and GNU
--files-with-matches) does what you want.
From the POSIX spec:
Write only the names of files containing selected lines to standard output. Pathnames shall be written once per file searched. If the standard input is searched, a pathname of "(standard input)" shall be written, in the POSIX locale. In other locales, "standard input" may be replaced by something more appropriate in those locales.
Both BSD and GNU also explicitly guarantee that this will be more efficient. (Older BSD versions say "…
grep will only search a file until a match has been found, making searches potentially less expensive", newer BSD and GNU say "The scanning will stop on the first match".) If you don't know which
grep you have and which options it has, just type
man grep at the shell and you should get the manpage.
How to get only filenames without Path by using grep
Yet another simpler solution:
grep -l whatever-you-want | xargs -L 1 basename
or you can avoid
xargs and use a subshell instead, if you are not using an ancient version of the GNU coreutils:
basename -a $(grep -l whatever-you-want)
basename is the bash straightforward solution to get a file name without path. You may also be interested in
dirname to get the path only.

How to grep only show path/filename?
grep -l will output JUST the names of files which matched, without showing the actual match.
grep listing filenames without content
grep -i -R -l "search keyword" location
to get the list of files which contain the keyword.
