I accidentally typed in cd ` into terminal today and terminal didstrange things.It put a >  signed on the next line followed by my cursor like it wanted some input. No matter what I entered continued to do the same thing until I terminated the command.Out of curiosity what happened? Was this a bug or a feature?
What is the effect of a lone backtick at the end of a command line?
shell;command line
Answered here already... essentially Everything you type between backticks is evaluated (executed) by the shell before the main command
