To add to this, zsh (or maybe just oh-my-zsh) has tab complete for globbing, so if you type echo foo/bar/*.py and hit tab, it will automatically expand into echo foo/bar/quux.py foo/bar/quux2.py foo/bar/quux3.py (assuming quux.py, quux2.py, and quux3.py are the only 3 python files in foo/bar/) This way, you can preview all the files that you are affecting before actually hitting enter and running the command. You can also recursively glob by doing echo foo/bar/**/*.py which will find all .py files in foo/bar and any subdirectories It's definitely worth installing and trying for an hour, you can decide if you like it or not!
