How do I find all files containing specific text on Linux?
grep -rnw ‘/path/to/somewhere/’ -e ‘pattern’
-r or -R is recursive,
-n is line number, and
-w stands for match the whole word.
-l (lower-case L) can be added to just give the file name of matching files.
Along with these, –exclude, –include, –exclude-dir flags could be used for efficient searching:
This will only search through those files which have .c or .h extensions:
grep –include=\*.{c,h} -rnw ‘/path/to/somewhere/’ -e “pattern”
This will exclude searching all the files ending with .o extension:
grep –exclude=*.o -rnw ‘/path/to/somewhere/’ -e “pattern”
For directories it’s possible to exclude a particular directory(ies) through–exclude-dirparameter.
For example, this will exclude the dirs dir1/, dir2/ and all of them matching *.dst/:
grep –exclude-dir={dir1,dir2,*.dst} -rnw ‘/path/to/somewhere/’ -e “pattern”
