Why does the command ps not display the entire list of processes?
If the command ps awx
is run the following output is produced. The list below is the last 20 lines of the complete output.
4247 pts/1 Ss+ 0:00 /bin/bash
4442 ? S< 0:00 [kworker/u17:1]
4661 ? S< 0:00 [kworker/u17:3]

5431 ? S 0:00 [kworker/7:0]
5562 ? S 0:00 [kworker/4:2]
5620 tty1 R+ 0:00 ps awx
If a subsequent command ps awx | grep grep
is run the following output is generated.
5646 tty1 S+ 0:00 grep --color=auto grep
Additionally if the following command ps awx | grep agetty
is run, the following output is displayed.
5669 tty1 S+ 0:00 grep --color=auto agetty
Why does the command ps awx
not display the process identification numbers 5646 and 5669? In fact there are no other processes listed after 5620.
