Code:
var=$(...)

Read the man page for your shell and search for Command Substitution.

Don't encourage someone starting out to use backticks. They're rubbish.

Using back tick will place the output of the command execution in the assigned variable.
i don't want to execute the command at this point in time.
Want the literal copy in the variable.. so that i can execute later

The $(...) notation is nicer all round.
