Search file by name
find . -iname “*abc.txt”
Search 'text' in any file
grep -rnw “/path/to/somewhere/” -e “pattern”
-ror-Ris recursive,-nis line number, and-wstands for match the whole word.-l(lower-case L) can be added to just give the file name of matching files.-eis the pattern used during the search
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 one or more directories using the
--exclude-dirparameter. For example, this will exclude the dirsdir1/,dir2/and all of them matching*.dst/:
