What version of Solaris?  The -e option to "test" is not portable to
older versions of UNIX.  Also (as on Solaris) some /bin/sh shells have
"test" as a builtin and those builtins don't support it.

You can use -f instead, if the thing you're looking for is going to be a
file.  Or, you can use -r if you know it's readable.  Those are both
more portable.
