A PID can have a maximum value of 32768. When that number is reached, Linux starts over and searches for a PID that is now available since a process that was previously its owner has ended. When Linux is started by the boot-up processes, the process with a PID of 1 is the first to run. That will be systemd on systems running systemd. On other systems, init is probably the default, while some Linux versions also utilize OpenRc or s6 as alternatives. We mentioned below are the ways to Find PID of a Linux Process With pidof or pgrep.
