tag/awk

If you work with text data files, you might have some cleanup to do before processing them. It can be reordering columns. Discarding unused data. Or fixing formating. Those are tasks the standard tool Awk shines at. So don’t wait to discover it in this video !

Converting a text to upper case? Well, that’s a simple question …​ with surprisingly subtle answers. Especially if you want to take into account internationalization issues…​ You’ve probably noticed from my accent (pun intended), I’m a French native speaker.

Awk is a powerful tool using pattern matching to identify the data to process in a file. But Awk patterns are much more versatile than their sed counterpart.
