What is the use of top command in Linux?
top command displays processor activity of your Linux box and also displays tasks managed by kernel in real-time. It’ll show processor and memory are being used and other information like running processes. This may help you to take correct action. top command found in UNIX-like operating systems.

From the top and htop outputs above, you’ll notice that there is a column called PR and PRI receptively which shows the priority of a process. This, therefore, means that: NI – is the nice value, which is a user-space concept, while. PR or PRI – is the process’s actual priority, as seen by the Linux kernel.

What is Kill 9 in Linux?
kill -9 Meaning: The process will be killed by the kernel; this signal cannot be ignored. 9 means KILL signal that is not catchable or ignorable. Uses: SIGKILL singal. Kill Meaning: The kill command without any signal passes the signal 15, which terminates the process the normal way.
