Yes, there are terminal apps for ChromeOS. There's an app store - two if you're on a model that supports Android apps - instead of a package manager. More importantly, there's crouton. You can use that to get at the real Linux (well OK it's Ubuntu) that lies underneath ChromeOS, with all of the terminal apps and package managers and compilers and whatever you might want. Better still, you can run all of that in a ChromeOS window, with full clipboard integration etc. so you can copy and paste between them.
