It will if /usr/bin/[ exists:
[EMAIL PROTECTED] ~]$ ls -l /usr/bin/[
lrwxrwxrwx 1 root root 4 Oct 4 2002 /usr/bin/[ -> test
[EMAIL PROTECTED] ~]$ rpm -qf /usr/bin/[
sh-utils-2.0.11-14
Or you can use this instead:
if test -f $FILENAME; then
...
fi
which will work on all shells.

I disagree. Use /bin/sh unless you really need something that bash
provides and sh doesn't.
