bye

bye [n]

bye is a zsh builtin that terminates the current shell session. It is functionally identical to exit. When called, it runs any EXIT traps and zshexit hooks before closing the shell.If an optional numeric argument is provided, it is used as the exit status returned to the parent process. Without an argument, the exit status of the last command executed is used.

bye is specific to zsh and not available in bash or other shells. For portability, use exit instead. If there are running background jobs, zsh may warn before exiting on the first attempt.

bye was included in zsh as a convenience alias for exit, reflecting a common command used in interactive systems like FTP clients and some early Unix shells.
