If a shell is not given on the command line, .B chsh prompts for one. .B chsh is used to change local entries only. Use ypchsh, lchsh or any other implementation for non-local entries. .SS VALID SHELLS .B chsh will accept the full pathname of any executable file on the system. However, it will issue a warning if the shell is not listed in the .I /etc/shells file.
