This post is Part 3 of a 10tutorial series, here in this part, we will cover how to archivecompress files and directories, set file attributes, and find files. In this short article, I will show you a simple but useful commandline trick how to view output of a command on the screen and also write to a file in Linux. Note If you inadvertently enter the crontab command with no arguments, do not attempt to get out with Controld. This removes all entries in your crontab file.

Wikipediampstat is a computer command line software used in unix type operating systems to report on the screen processor related statistics. It is used in computer monitoring in order to diagnose problems or to build statistics about a computers CPUusage. DescriptioneditThe mpstat command writes to standard output activities for each available processor. The mpstat command can be used both on SMP and UP machines, but in the latter, only global average activities will be printed. Interval is the time in seconds between printing out a line of statistics. Count is the number of lines of output you want. Note that the first line of output from mpstat like iostat, vmstat, etc. The subsequent lines will show current values. ExampleseditExample of output under linux. Linux 2. 4. 2. 1 3.
