HowTo Geek ☛ Never Used Linux Terminal Wildcards Before? Here's How to Get Started
You may have seen weird characters in shell commands, but what can they do? These are called "wildcards," and they can make your life in the Linux terminal much easier.
What Are Wildcards?
Wildcard characters, also known as metacharacters, are characters that can stand for other characters. They're similar to "wildcards" in card games that can be used as other types of cards.
Wildcard characters are used to generate lists of filenames to feed to other utilities. If you have a large number of files you want to operate on, you can use a wildcard operation to save time on typing.
It's the shell that handles these operations, not the programs. If you type an expression with wildcard characters in it, the shell will see it and fill in the files that match it, then pass it along to the program. The program won't see the wildcard characters.

I’ve made a concerted effort over the years to embrace the power of the Terminal, and you should too. In fact, you could be reading this article right now from the command line.
