Question

Transcribed Image Text:init is the grandfather of all processes.
init
All processes running in Linux can trace
their relationship back to init.
PID = 1
PPID = 0
Processl is a child of init
and a parent of Process2.
Process3 is both a child and a parent.
It is a child process of init and a paren
of processes 4 and 5.
Process1
Process3
A process may have any number of
child processes, but it may have only
one parent process.
PID = 101
PID = 1034
PPID = 1
PPID = 1
The PPID of a child
is the same as the
PID of its parent.
Process2
Process4
Process5
Process2 has a PPID
of 101 because its
parent is Process1,
PID = 3240
PID = 1888
PID = 2056
PPID = 101
PPID = 1034
PPID = 1034
which has a PID of 101.
Process2 is a child
of Process1.
Process lineage may extend
to multiple levels.
Process6
Process7
PID = 1289
PID = 1844
PPID = 1888
PPID = 1888
Each PID is unique, but
duplicate PPIDS are allowed
since a parent process may
have several child processes.
