How to Use Grep Command

Description
The grep command searches an input for the regular expression (pattern of characters) that you specify and displays every line that contains the pattern. Your input can be one or more files or an output of a command using pipes.

Command Syntax
grep [options] PATTERN [file(s)]

OPTIONS
-n display line number of match
-i case-insensitive 
-l list only filenames that contain a match, once each
-w expression is search for as a word

Note: If your regular expression contains a special character, you must enclose it with single quotation marks because these special characters may have a special meaning to your shell. The single quotes prevents the shell from interpreting them. If you are searching against multiple files that contains the regular expression, the name of the file will be displayed in the output.
