Thank-you Rick. So if I did not already know that "xeyes" is all lower case, I would have to do "[Xx][Ee][Yy][Ee][Ss]"? Am I understanding things correctly? I'm actually looking for repository sources for at least 6 Python development environments, and it's not clear when a letter should be upper case in the names of those IDEs for Python. I looked up globbing, which is what (according to the dnf man page) dnf uses for wildcarding. It provides a way of matching zero or more characters ('*'), any character in a set or range of characters ("[{whatever}]"), and any character not in a set or range of characters ("[!{whatever}]"). I did not see a way of matching zero or one characters. Did I miss something? Such a globbing ability would help with finding (for example) "x-eyes" vs. "x_eyes" vs. "x.eyes" vs. "xeyes". It is curious that you do "dnf whatprovides", but the man page for dnf does not list "whatprovides" as a command, but rather as an option for other commands. Is the man page wrong (or at least incomplete)?
