Searching file content using GREP

No Comments

A nice and easy way to search files for specific content in the files using GREP.

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"

For more options check man grep.
