bash versus sh test builtin

[Jeffrey Goldberg]

The -ne operator for [ in /bin/sh doesn't seem to work as in bash.   
Also the bash behavior here is what matches /bin/[ most closely.


$ /bin/sh
$ if [ $UID -ne 0 ] ; then
 > echo not root
 > fi
[: -ne: unexpected operator
$ exit
$ echo $SHELL
/usr/local/bin/bash
[jeffrey at dobby ~/src/mount-rsnap]$ if [ $UID -ne 0 ] ; then
 > echo not root
 > fi
not root

Does anyone have a recommendation of how to run this simple test in / 
bin/sh and how to write tests reasonably portably?
