Subject:	bash test -n && test -z return tru
X-IsSubscribed:	yes

from reading the bash man pages, I would have thought the -n and -z were 
mutually exclusive.  Therefore I don't understand this result:

~>$ [ -n $(which nonexisingfilename 2>/dev/null) ] && [ -z $(which 
nonexistingfilename 2&>/dev/null) ]  && echo hello
hello
~>$

can anyone help explain this?
