From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You're probably wanting
[ -z "${VAR1}" -a -z "${VAR2}" ]. Note in bash that there are minor differences in how[ ]and[[ ]]tests are handled. You can pull up a handy cheat sheet of the operands on most distros by runningman test, though you'll need to read through the CONDITIONAL EXPRESSIONS section ofman bashif you want to see the minor differences of the single vs double square bracket commands (mostly whether locale applies to string order, as well as whether operands are evaluated in numeric comparisons).
