pidof - with the id of a process running , so are just these 2, the 2 running the ssh

pgrep instead (as pkill) - find or send signals to processes that contain these names or attributes. For that appear more, all
and
ps | grep - bring everyone to the same grep, which is a pid fijense more than


pgrep man pgrep From:

DESCRIPTION ; pgrep looks Through the Currently Running Processes and lists the process IDs Which matches the selection criteria to stdout. Have All the criteria to match. For example,

;; $ pgrep -u root sshd

       will only list the processes called sshd AND owned by root.  On the other hand,

              $ pgrep -u root,daemon

       will list the processes owned by root OR daemon.

       pkill will send the specified signal (by default SIGTERM) to each process instead of listing them on stdout.
