does the `( )' create a subshell?

does the `( )' create a subshell? if so, in `( ps )' command, why i can not see the subsell?

I don't know. It works for me.

Code:

david:~$ ps

  PID TTY          TIME CMD

 3565 pts/1    00:00:00 bash

24991 pts/1    00:00:00 ps

david:~$



david:~$ (while [ 1 ]; do  echo "Subshell running"; done; )

Subshell running

Subshell running

Subshell running

Subshell running

Subshell running

Subshell running

Subshell running

Subshell running

...

<crtl+z to suspend process>

    echo "Subshell running";

done )
