If your grep doesn't have an -o option, you can use sed instead.

What Others Think

Good for recursive. If you don't want recursive, try: ls -Xp | grep -Eo "\.[^/]+$" | sort | uniq

There may be a better way to do it, but that is one way to do it. What if, for example Tech Holding, there were 5,000 files but only one JPG?

When you add fresh content to this site, I hope you will ping me immediately. I can then make sure I am not overlooking anything you are putting on this page. Nicholas Rutherford It is wonderful to be informed by you. It would be absolutely great if there was a facility like it.

It's only been a few months since I joined the page and most of the posts are too specific that I don’t know exactly how to implement them on the programs. I would suggest a better explanation of the scenario and a great deal of information so newbies like me could understand and follow these threads. Inventory Management Software Dubai
