~/.TOPRC file. This is the recommended way to write top configuration files.As you can see, the top command is a very powerful tool for monitoring systems and is especially important for system administrators. However, its disadvantage is that it consumes a lot of system resources.Application examplesYou can use the top command to monitor a specified user, and the default is to monitor processes for all users. If you want to view the situation of the

multiple users to the system, the number of users here will also be the number of terminals; "Load average" is the average value of the current system load. The following three values are the average number of processes 1 minute ago, 5 minutes ago, and 15 minutes ago, respectively, generally, when this value exceeds the number of CPUs, the CPU will be overloaded with the processes contained in the current system; Line 2 (tasks ): "59 total" indicates the total number of processes in the current
