Sed and Awk tutorials January 2015

I just ran into amazing tutorials for sed and awk, two famous text processing tools on unix.

If you are on firefox I advise you to disable CSS (View > Page Style > No Style)


$ echo day | sed s/day/night/

Well done! You've reached the end of my post. Now you can leave me a comment :)
