On Linux, I’d like to know which command I use to display the PGID of the proceedings under implementation.
I saw in a reply here on Soept that we could kill a process (command Kill) using the process PGID. But using the command ps I only see the PID.

You can use the ps even, passing the option j. In the example below the -e is used to show all processes.
ps -ej
If you want to know more, see man of ps:
man ps

I’ll just show you one more way to do that I found. It’s quite flexible:
Using the command ps same. But passing options to the command. This is the call signature:
ps o <campos a ser exibido>
Examples:
Simple call:
[root@alab ~]# ps
PID TTY TIME CMD
1946 pts/0 00:00:00 bash
1966 pts/0 00:00:00 ps
Call with the PGID:
[root@alab ~]# ps o pgid
PGID
1463
1465
1467
1469
1475
1582
1946
1970
Notice that when we pass the o We must tell you exactly what columns we want to display. So to get something more complete and add the PGID we can use the command as follows:
Most complete call:
[root@alab ~]# ps axo pid,pgid,tty,time,comm
PID PGID TT TIME COMMAND
1 1 ? 00:00:00 init
2 0 ? 00:00:00 kthreadd

1467 1467 tty4 00:00:00 mingetty
1469 1469 tty5 00:00:00 mingetty

1975 1975 pts/0 00:00:00 ps

It is also possible to kill the process using the
PID. Why specifically use thePGID? It is to kill all processes of a group of users?– Yamaneko
