Answer:
ps is the command that enables you to find the process id so that you can stop that process. In fact, ps is an abbreviation of "Process Status".
Explanation:
ps is a Unix/Linux command which is commonly used to find information on current running processes in a computer. The process id will be shown in a column named "PID". The other useful information shown by the ps command includes the amount of CPU time in minutes and second that a process has been running ("TIME").
In practice, ps is used along with another Unix command, kill, to identify a target process and stop the process. Firstly, ps command is used to identify the PID of a target process (e.g. the process that consume most of the memory and CPU resources). It is then followed with fetching the PID to the kill command to stop the process.
