Existing or Predefined Variables

The predefined variables are either shell (local) or environment (global) variables.

In C shell, the shell variable is set using the set command:

You simply assign a value to a variable, in this case, it is y and then check its value.

$ set y = 100

$ echo $y

100

If the value has a space or a special character than can get the shell confused, you must use double quotes. The dollar sign is needed before the variable to see its value using the echo command.

$ set x = "Hello World"

$ echo $x

Hello World
