The Linux kernel doesn't consider itself a process, therefore it has no process id.
init.Answer:'init' is always process ID 1.
A PID is a process ID. It is generally a 15 bit number, and it identifies a process or a thread.
fg [job id]where [job id] is the job number associated with the process. You can find the job id by issuing the jobs command.
83
The Linux kernel does not have a process id (also called pid). Process 1 is almost always the process scheduler, init. PIDs are assigned to each subsequent process that is started and they will usually vary. Do not remove init, doing so would likely have catastrophic consequences, a kernel panic for instance. Unless you particularly enjoy using the crash utility. $ man crash [JMH]
82 => Linux swap / Solaris 83 => Linux ext2 & ext3 85 => Linux Extended partition
In reference to Linux, PID is Process Identification Number.3 digit number on the back of credit cards.In unix systems, a PID is a process ID. It is generally a 15 bit number, and it identifies a process or a thread.
Process Group ID. A process Group is formed when we couple multiple processes together . e.g. from command line. $ ls | more Here, ls & more will have the same PGID.

Processes aren't "deleted", they are "killed." The "kill" command, followed by the process ID number, should kill the process. Most distros also have a "killall" command, which will kill processes that have the name you specified.
Linux is an operating system on which lots of system distributions, such as Ubuntu, Android, Chrome OS, Archlinux, are built.
