Your user info will open up in your editor of choice and you'll have to change the shell line to point to the shell you want -- make sure you point to a valid shell!

You can use the -s flag to set it without actually going into an editor:

dave@samizdata:[~]% chsh -s /usr/local/bin/zsh

Note that if you change a user's shell to something that isn't actually a shell, you can break their login -- intentionally, if you want to block the user from logging in and you switch the shell to /sbin/nologin or another invalid shell, for example, or unintenionally, if you give them a misspelled shell or point to a shell that isn't on a mounted volume (e.g., the shell is in /usr/local/bin/bash and /usr/local/ isn't mounted).

Also note that some programs (several ftp daemons, for example) won't allow the user to log in if they don't have a valid shell.
