Yes, there are. Microware’s MShell, an enhanced shell. In addition, there are several public domain shells available. The most notable of which is the Bourne shell, sh, available in the TOP package (OS-9/68000) in its original version. A newer version with may enhancements and bug fixes is available through EFFO. sh supports aliasing, command-line editing, history, environment variable replacement, shell scripting, the `command` operator (which uses the output of the command as arguments to the called program), and a startup file. For users feeling at home in a VAX/VMS surrounding, the zsh shell is commercially available from ELSOFT.
