To see your current shell along with it’s process ID, the process ID of parents and the process ID of current command use:
$ pstree -aps $$
systemd,1 splash fastboot kaslr
└─lightdm,1050
└─lightdm,1294 --session-child 12 19
└─upstart,1883 --user
└─gnome-terminal-,10481
└─bash,3612
└─pstree,15684 -aps 3612
$$is the environment variable for the shell’s process ID (3612).
