Linux grep command summary with examples

thank you sir

New in July 2017! Find all of the code for this video on our website. See link in Description.

As mentioned, check out the Description for a link to the article on Regular Expression, sometimes referred to as regex.  It basically attempts to standardize the way to search and identify patterns in text using symbols.  If you think about it, there must be a standard and many languages have their own.  In order for regex to work, some characters (like * we've seen) have special meanings while others have literal meanings.  It's a worthwhile read.  Also spend a little time in the grep manual page.  -Paul
