[wplug] vars in bash?

[Michael Semcheski]

Zach,

Here's my (possibly flawed) understanding:

The first form (sans export) declares a variable.  That variable is only
defined in the context of the script.

The second form (with export) declares an environment variable.  That
is, the exported variable will be available after the script finishes in
the case of .bashrc. 

Make sense?  Anyone dispute what I said?
