Terminal runs processes by itself

Days ago, I noticed that my terminal runs processes in the background when I want to close it a pop-up show that "Closing this window will terminate the running processes: -zsh, sleep".

What does it mean and how can I stop it?

Thank you.

check you Terminal> Preferences>General for running command or default

What job is running,(?) copy and paste:

job

Terminal, Command Z might simply suspend, however Command C will quit.

*Some applications will trap control C and ignore it. You may need to enter multiple instances of Control \ to get the job done. The latter will also pop a dialog with obvious buttons about reporting to Apple or not.

Also, Control D will kill the shell running in the Terminal, or the actual Terminal window will also disappear — but not the running Terminal application itself.

You can always kill a job, from Terminal, copy and paste:

kill %1
