If you’re anything like me, you’ve always got a Terminal window open, and you probably have even assigned a hotkey to bring it up anytime. So why open up the boring calculator when you can solve equations right there on the command line?
This is a simple method for creating a calculator using the built-in function support in the Bash shell. Essentially all we’re doing is assigning the question mark to run the bc command with whatever arguments you type after it.
