Sorry, this is wrong, here is the right screenshot:
$ ps
    PID TTY          TIME CMD
    538 ttyS0    00:00:00 login
    573 ttyS0    00:00:00 bash
   8282 ttyS0    00:00:04 example:2
   8825 ttyS0    00:00:00 ps
$ ps a
    PID TTY      STAT   TIME COMMAND
    538 ttyS0    Ss     0:00 /bin/login -p --
    540 tty1     Ss+    0:00 /sbin/agetty -o -p -- \u --noclear tty1 linux
    573 ttyS0    S      0:00 /bin/bash -li
   8282 ttyS0    RLl    0:05 /usr/bin/example
   8829 ttyS0    R+     0:00 ps a

It fixes the issue.


Thank you,
