A community to discuss about Bash.

Bash is a Unix shell and command language written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell. The shell's name is an acronym for Bourne-Again SHell, a pun on the name of the Bourne shell that it replaces and the notion of being "born again".

Keep discussion limited to Bash and projects around it. Feel free to share resources, self-projects, tutorials or any other cool stuff related to Bash.

How do you check if a file ends in a certain file extension in bash? (lemmynsfw.com)

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.

It would also return non-file objects, like directories
