Bash: infinite sleep (infinite blocking)

I use startx to start X which will evaluate my .xinitrc. In my .xinitrc I start my window manager using /usr/bin/mywm. Now, if I kill my WM (in order to f.e. test some other WM), X will terminate too because the .xinitrc script reached EOF. So I added this at the end of my .xinitrc:

while true; do sleep 10000; done

This way X won't terminate if I kill my WM. Now my question: how can I do an infinite sleep instead of looping sleep? Is there a command which will kinda like freeze the script?

Solution

  • sleep infinity, if implemented, will either sleep forever or sleep for the maximum sleep length, depending on the implementation. (see other answers and comments for this question that mention some of the variations)
