How to suppress output of timeout -s 9 1 sleep 2 command in linux?

Question

linux

The standard option through stream redirection and output to devnul does not help
timeout -s 9 1 sleep 2 2>&1 >/dev/null
Killed
Still produces killed

Answer 1

Anything after '1' is treated as part of a command that is executed inside timeout
Try something like:
UPD:

`timeout -s 9 10 sleep 2` >/dev/null 2>&1
#или
`timeout -s 9 10 sleep 2 >/dev/null 2>&1` >/dev/null 2>&1
