Seriously. There doesn’t seem to be a way to do this. Every thing I ever try I just get bad substitution errors. The internet is full of people posting code that’s supposed to compare file extensions but none of it works. I’ve spent all morning trying everything I could find. I already gave up and I’m making this progeam in python instead but now I’m curious. How tf do you actually compare file extensions? If I have a folder fill of files and I want to run a command only on the png files, there seems to be no way to actually do this.
If someone posts “[[ $file == *.txt ]]” I’m going to fucking scream because THAT DOES NOT WORK. IT’S NOT VAILD BASH CODE.
What’s the benefit of spawning a subshell and executing “ls” here instead of just passing a glob to your loop?
