You can use the command grep 'word' filename.txt to search for 'word' in 'filename.txt'.

What if I want to search recursively in all files in a directory?

You can use grep -r 'word' /path/to/directory to search recursively in all files within the specified directory.

Are there options to ignore case sensitivity?
