How do I make timeout not print any text?

You may need to redirect both stdout and stderr:

timeout 2 >NUL 2>NUL

Note that the special device is NUL or NUL:, with a single L.

Interesting (and annoying) fact for latest Windows 10: Microsft does not allow piping into nul any longer.

Update: This was a bug in Win10-Insider v18990. It is fixed in v18995.
