Linux How To Understand These BOOT, START, SHUTDOWN

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.


  • 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.
