If open a terminal window then close it I’m warned I will terminate a process called -zsh, Sleep. This isn’t something I’ve noticed in the past and would like some help to figure out why and if this is normal behaviour. Thanks.
MacBook Pro 15″, macOS 11.3
When you launch the Terminal, it will also open with the Zsh shell. As long as there is no activity in the Terminal window, the UNIX kernel will sleep the Terminal and Zsh shell until there is activity (you enter something) in the Terminal. Typing a control+d will exit the existing Zsh shell and render the current Terminal session useless until you quit the Terminal and relaunch it.
All that gibberish on top of your Terminal window is configurable, and in my case, I find it distracting and only have the Terminal name (default) on its title bar. In Terminal Preferences, mine looks like this:
Have not set tried invoking caffeinate -I in Big Sur. So do not know it it even works? Maybe you did and by closing the Terminal Application the warning was alerting you the command was still running ? Pure guess work on my part.
I am running Big Sur 11.3.1 and I cannot duplicate your error dialog when using the red traffic light to close the Terminal window, by pressing control+d to end the current session or simply pressing command+q to formally quit Terminal.
If I press control d then close its closes with out the warning. Is their a way to check what process is running and find out what it’s doing?
Would command z suspend the running command like in Catalina ? and thusly Red traffic light or command q would function without the Warning experienced by the Original person ?
Does the name of the terminal window have anything to do with it as it just used to show my name now it’s my name plus zsh sleep. I have no idea where this has come from or what’s it’s doing.
Thanks for the info. I was worried it was something suspicious happening. Take care.
You are welcome.
zsh sleep terminal process
