Without a doubt, grep is the best command to search a file (or files) for a specific text. By default, it returns all the lines of a file that contain a certain string. This behavior can be changed with the -l option, which instructs grep to only return the file names that contain the specified text.
You can use grep tool to search recursively the current folder, like: grep -r "class foo" . Alternatively, use ripgrep .
This tutorial uses the 'grep' command to search for strings in files. Alternatively, you may use the find command to look for files with specific content. The grep command offers other useful options for finding specific text in file systems. --exclude-dir=PATTERN : directories that match PATTERN will be skipped.
The grep command searches through the file, looking for matches to the pattern specified. To use it type grep , then the pattern we're searching for and finally the name of the file (or files) we're searching in. The output is the three lines in the file that contain the letters 'not'.
By using grep command, you can achieve what you expected
grep -rlnw '/path/to/somewhere/' -e '0774386850'
-r or -R is recursive,
-n is line number, and
-w stands for match the whole word.
-l (lower-case L) file name of matching files.
