In man-page contains the wrong information:

...
string1 < string2
       True  if  string1  sorts before string2 lexicographically in the
       current locale.
string1 > string2
       True if string1 sorts after  string2  lexicographically  in  the
       current locale.
...

Constructions "<" and ">" is illegal.

Bash consider ">" and "<" operations at the "[...]" constructions as
redirections. This operations don't work in zsh, ash too, but are described in
their man-pages.

What suggestions?
