The top command is a Linux command that shows the running processes on the system. It provides a
dynamic real-time view of the system performance and resource usage. The top command can
display various information about the processes, such as their process ID, user, priority, state, CPU
and memory usage, command name, and more. The top command can also sort the processes by
different criteria, such as CPU or RAM consumption, by using the interactive commands. The top
command is useful for monitoring the system load and identifying the processes that are consuming
the most resources. Reference:
