Subject: Best Way to Test an Environment Variable
Date: Wed, 14 Oct 2015 23:10:26 -0700	[thread overview]
Message-ID: <e1edacefa7810f717d82c35449f30080.squirrel@legacy-webmail.sonic.net> (raw)
In-Reply-To: <CAPTyOgfzxzWi83Y6hkbZAhgi9mCQDPV_Z-FR9egu1S7QkcJUSQ@mail.gmail.com>

Hi -

I've been using:

if [ -z $ENV_VAR ]; then

    <do stuff>
fi

To test environment variables. It seems to work.

But I'm curious - is there a better way in zsh to test an environment
variable?

Thanks,



Corwin
