Linux’s ps (processes status) is used to check the information on its running processes. The process is nothing but a program in Linux/Unix to execute a specific task. The ps command in Linux is used to monitor all the currently running activities along with USER, PID, %CPU, %MEM, VSZ, RSS, TTY, STAT, START, TIME, COMMAND. It helps, mostly to the System Administrators to find the PID (processes identifier) of all the running processes to monitor and troubleshoot.
