Every question and answer I've seen so far is ancient or just about grep in the terminal.
I want an easy way to search my ~/code folder for certain strings. And I want the interface to allow filtering by file extension, etc.
I thought this would be built into Ubuntu. Is it?
Have you tried
catfish? It is available from the App Center and looks like it can do what you want. I tried it but, being a command line addict, I personally love the level of power, flexibility and speed thatfindandgrepcan provide. Hope this is useful.
