Y broses Init yw mam (rhiant) yr holl brosesau ar y system, hon yw'r rhaglen gyntaf a weithredir pan fydd y system Linux yn rhoi hwb i fyny; mae'n rheoli pob proses arall ar y system. Mae'n cael ei gychwyn gan y cnewyllyn ei hun, felly mewn egwyddor nid oes ganddo broses rhiant. Mae gan y broses init ID proses o 1 bob amser.

How do I find parent process?
Esboniad
- Diffinnir $ PPID gan y gragen, dyma PID y broses riant.
- yn / proc /, mae gennych rai dirs gyda PID pob proses. Yna, os ydych chi'n cath / proc / $ PPID / comm, rydych chi'n adleisio enw gorchymyn y PID.
Beth yw Pgid yn Linux?
PGID. Mae pob proses mewn grŵp proses yn rhannu a ID grŵp proses (PGID), sydd yr un fath â PID y broses gyntaf yn y grŵp proses. Defnyddir yr ID hwn ar gyfer prosesau sy'n gysylltiedig â signalau. Os yw gorchymyn yn cychwyn un broses yn unig, mae ei PID a PGID yr un peth.
