Thread: single environment variable

What is a single environment variable? I'm having trouble defining it. And how do you disply it?

>What is a single environment variable?
Just a simple environment variable.

>I'm having trouble defining it.
Depends on your shell, here are two common ones

bash:

Code:

$ export OOGA="This is a simple environment variable"
$ echo $OOGA
This is a simple environment variable

tcsh:

Code:

% setenv OOGA "This is a simple environment variable"
% echo $OOGA
This is a simple environment variable

Pretty much any other common shell will be a derivative of one of those two. Check your friendly neighborhood man pages to see how to do it with your shell.

>And how do you disply it?
What do you know, I answered two questions with one answer. Look above to see a way to echo a shell variable.
