HOWTO: Use Shell Wildcards
We’re all familiar with some of the more common wildcard characters like * and ?, but most shells offer a lot more than that.
First off, there’s some invisible magic that most of us probably don’t care about, but should be mentioned. When your hacking away at the command line, you’re actually operating within a ’shell’. Probably the most common shell on GNU/Linux systems is the Bourne Again Shell which is typically just called BASH. The shell takes the commands you type in, does whatever needs to be done to them, and passes them off to the system to deal with. I’m gonna go way out on a limb here and state that the shell is also responsible for presenting the output from said commands back to you.
