linux – How can I exclude directories from grep -R?

Recent versions of GNU Grep (>= 2.5.2) provide:


which excludes directories matching the pattern dir from recursive directory searches.

So you can do:

grep -R --exclude-dir=node_modules 'some pattern' /path/to/search

For a bit more information regarding syntax and usage see

For older GNU Greps and POSIX Grep, use find as suggested in other answers.

Or just use ack (Edit: or The Silver Searcher) and be done with it!

SOLUTION 1 (combine find and grep)

The purpose of this solution is not to deal with grep performance but to show a portable solution : should also work with busybox or GNU version older than 2.5.

Use find, for excluding directories foo and bar :

find /dir ( -name foo -prune ) -o ( -name bar -prune ) -o -name "*.sh" -print

Then combine find and the non-recursive use of grep, as a portable solution :

find /dir ( -name node_modules -prune ) -o -name "*.sh" -exec grep --color -Hn "your text to find" {} 2>/dev/null ;

SOLUTION 2 (using the --exclude-dir option of grep):

You know this solution already, but I add it since it’s the most recent and efficient solution. Note this is a less portable solution but more human-readable.

grep -R --exclude-dir=node_modules 'some pattern' /path/to/search

To exclude multiple directories, use --exclude-dir as:



If you frequently search through code, Ag (The Silver Searcher) is a much faster alternative to grep, that’s customized for searching code. For instance, it automatically ignores files and directories listed in .gitignore, so you don’t have to keep passing the same cumbersome exclude options to grep or find.

linux – How can I exclude directories from grep -R?

If you want to exclude multiple directories:

“r” for recursive, “l” to print only names of files containing matches and “i” to ignore case distinctions :

grep -rli --exclude-dir={dir1,dir2,dir3} keyword /path/to/search

Example : I want to find files that contain the word ‘hello’. I want to search in all my linux directories except proc directory, boot directory, sys directory and root directory :

grep -rli --exclude-dir={proc,boot,root,sys} hello /

Note : The example above needs to be root

Note 2 (according to @skplunkerin) : do not add spaces after the commas in {dir1,dir2,dir3}
