How do i find all files containing specific text/substring ?


We propose here an easy and immediate method to search all the files containing our string.


# List every number:line that contains SUBSTRING
# "r": read recursively all files under each directory
# "n": line number of each matching text/substring 
# "w": select only those  lines  containing  matches  that  form  whole words
# "i": case insensitive
# "l": Suppress normal output; instead print the name of each input file from which output would normally have been printed.
clear; grep -rni  "./"  -e "SUBSTRING"
