Re: ReturnsZero(): command does not return zero. Is class created with value of false?

[Mark . Burgess]

I'm sorry -- I didn't read this properly first time
around. the problem is a misunderstanding of the ReturnZero()
function. It is the value of the shell returncode that is tested
not the value of the text string printed by the command.
You will need to use StrCmp("0",$returnvar) if you want to test that.
Since fgrep will always succeed if /etc/passwd exists, it will always
return zero in the sense of ReturnZero().

I believe it is explained in the manual that classes are attributes
that are either defined or not. It is certainly implicit in all
of the docs, but whether or not it is clear is of course a matter
of opinion! :)
