Understand these terms while dealing with inter-process communication in Linux operating systems. Here is the right way to use BOOT, START, STOP, and SHUTDOWN mindfully to save resources.
Booting and Shutdown Process in Linux
BOOT Process
- Here the BOOT signal restarts that process from the beginning stage. Also, it starts its associated sub-processes involved.
- The Linux-based operating systems support the design of inter-process communication from program to program.
- So, BOOT you need to use when you first-time start the process.
START Process
- The start process doesn’t start from scratch. It just enables that previously disabled. All the sub-process as those already active, so it saves resources.
- After the STOP process, you can use the START process safely.
SHUTDOWN Process
- Here the shutdown makes down all the associated sub-processes. Usually, SHUTDOWN takes extra CPU time – as it has to shut down all the related ones.
- Usually, after SHUTDOWN, you can use BOOT – since this starts all the associated required processes.
So, use these signals mindfully while dealing with inter-process, especially in LINUX operating systems.
STOP Process
- The stop process will not stop all the associated processes from scratch.
- After the START process, you can use the STOP process safely.
Linux Tips & Tricks
- To shutdown Linux system use $ shutdown -h (h means halt)
- To reboot Linux system use $ reboot
- To power off Linux system use $ poweroff
