Of course.  Why ‘command’ otherwise?

Also:

        $ (exec cat) &
        [1] 31427
        $ ps --pid $! --ppid $!
          PID TTY          TIME CMD
        31427 pts/3    00:00:00 cat

Which, IIUC, is somewhat closer to what other shells do, though I cannot come 
up with any idea what practical difference it might make.
