Answer 2

This is known as the Back Quote. It is basically used for composing textual documents and sending computer commands. As for the commands, in the Linux shells, the backtick is used as an indication of what to execute a command. It's like, wherever the Linux compiler sees this back quote it executes the enforced command followed by the quote.
