In Unix/Linux operating systems, processes can be in one of the following states: 1. RUNNING & RUNNABLE 2. INTERRRUPTABLE_SLEEP 3. UNINTERRUPTABLE_SLEEP 4. STOPPED 5. ZOMBIE Let's discuss these states in this article. Fig: Process State transition diagram RUNNING & RUNNABLE When the CPU executes a process, it will be in a RUNNING state. When the...

There are different options to terminate a process in Unix/Linux flavour of operating systems. This article intends to list down those options. kill You can use the 'kill' command to terminate a process by passing the 'process id'. kill {PID} PID - is the 'process Id' of the process that you want to terminate. If... Continue Reading →
CPU consumption in Unix/Linux operating systems are studied using 8 different metrics: User CPU time, System CPU time, nice CPU time, Idle CPU time, Waiting CPU time, Hardware Interrupt CPU time, Software Interrupt CPU time, Stolen CPU time. In this article let us study about ‘waiting CPU time’. What is ‘waiting’ CPU time? Waiting CPU... Continue Reading →
