Back quote

Alternatively referred to as an acute, grave, grave accent, left quote, open quote, or a push, the back quote or backquote is a punctuation mark (`). It can be found on the same U.S. computer keyboard key as the tilde. Below is an example of a Perl code that uses back quotes to execute a system command and loads the command results into an array.

@files = `dir /b c:\windows\temp`;

Although not as common as the above uses, this mark is also sometimes referred to as a back prime, back tick, birk, blugle, quasiquote, and unapostrophe.
