In bash, background tasks continue running when the shell exits. For example here, dolphin continues running after the exit: This is what I want as the default behavior. In contrast, zsh’s behavior is to warn about running jobs on exit, then close them if you exit again.

How to exit Bash but leave running jobs open?

If you often start jobs that should go on even when the shell has exited, then you can set the option NO_HUP, and background jobs will be left alone. I have found that using a combination of nohup, &, and disown works for me, as I don’t want to permanently cause jobs to run when the shell has exited.

How to define an environment variable in zsh?

In zsh, environment variables appear as ordinary shell parameters, although they have to be defined slightly differently: strictly, the environment is a special region outside the shell, and zsh has to be told to put a copy there as well as keeping one of its own.

The file can’t be executed due to the wrong permissions. Bumping permissions up to 500 (execute permission granted) works fine too – with these permissions, the file executes fine: This is all as expected.

What’s the difference between Bash and zsh for login?

All that changes is that zsh will be the default login shell for new accounts, and even then, you can select bash instead. Scripts are not affected. What changes is the shell for interactive use, i.e. the shell in terminals (and also a few other things that use the login shell, such as crontabs).

What’s the difference between Bash and zsh arrays?

The result of an unquoted command substitution is split at whitespace but the pieces don’t undergo wildcard matching. Bash arrays are indexed from 0 to (length-1). Zsh arrays are indexed from 1 to length. With a= (one two three), in bash, $ {a [1]} is two, but in zsh, it’s one.

Why is Catalina defaulting to bash instead of Zsh?

Note the funny (read: insane) non-login condition for executing bashrc: it is often worked around by having the profile execute bashrc anyway. Zsh always executes zshenv. Then, depending on the case: run as a login shell, it executes zprofile; run as an interactive, it executes zshrc; run as a login shell, it executes zlogin.

How to load bash profile from within zsh?

If you’d like to be “profile-centric”, you can create .profile as a single source of truth, then load it from both .bash_profile and .zprofile. I found this helped bash scripts find the right PATH, etc., and helped me keep configuration in one place.
