I run zsh from bash after connecting SSH – how can I exit both with only one command

bashsshzsh

I run zsh on my server and I want to alias the exit command, because whenever I try to terminate my SSH session I must exit from zsh and exit from bash.

I tried alias exit='exit;exit' to no avail.

I don't want to change how I start zsh but I think it's not a very good solution. I've appended zsh to /etc/profile.

How can avoid to type exit twice to terminate my SSH session?

bash is the default login shell of your account on that system. To change it, do what @KevinPanko suggests. Then bash won't start, only zsh. Given that, through /etc/profile, you're always starting zsh at the moment (and not just sometimes), that would probably the best way to do it.

Alternatively, you can use the exec built-in command of bash to replace your bash process. man bash states:

exec ... [command [arguments]]

If command is specified, it replaces the shell. No new process is created. The arguments become the arguments to command.

So you can run zsh like this:

exec zsh

Afterwards, if you exit zsh, you exit the only shell you're running, and quit immediately.
