Linux Question

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?

Best regards

Answer

Maybe this seems ugly, but why not just run cat and let it wait for input forever?
