It works for me under Solaris 10. Perhaps Solaris 9 or older do not have a standard compliant /bin/sh program. What do you suggest we use instead as a workaround?
For backward compatibility reasons sh in Solaris 9 and earlier is not POSIX compliant. Use /usr/xpg4/bin/sh or /bin/bash instead.
(Unfortunately you can't cheat and define a shell function, although you could create a program called "!":
if ${1+"$@"}; then exit 1 else exit 0 fi
Actually this is what the script used 'til someone pointed out to me that sh has the ! syntax :-). I'll switch it back to using this style with a note to say why.
