 Don't even think about to edit these files by hand.  Use the command
"vipw" (and if you don't like the vi, which I doubt, set the env-variable
EDITOR to your choice) (see "man vipw", "man passwd", "man chsh")

 There is another legal way to change the settings: chsh

 Actually installing a shell also requires an entry in /etc/shells (see
"man shells").

 It wouldn't help to have the path set to /usr/local/bin if the shell
doesnt start...
