In this video we discuss regular expressions, how to use them, and regex 101. Corrections: As @Vladimir Mišev pointed out in the comments, GREP does not stand for the GNU Regular Expression Program, but instead stands for g/re/p "globally search a regular expression and print" and was written by Ken Thompson in 1974. I don't know where GNU Regular Expression Program came from - maybe that's the name of the GNU's version or something. Additionally, when demoing regex101, I said you could repeat a pattern in parenthesis, but meant, and typed curly braces { }. It was late, I was tired. Thanks for all the good feedback! -------------------------------------------------- ... https://www.youtube.com/watch?v=Z0KDrU4Wk2s

In this video, I talk about the virtue of unix/linux user groups. They've declined in popularity over the years, but I still think they're incredibly useful. If you're new to linux/unix administration, they can be a great way to find mentors and network for finding a job. It's also a great way to meet like-minded interesting people.
