This subchapter looks at uptime, a UNIX (and Linux) command.
uptime gives information about your server’s total uptime statistics.
Type uptime:
$ uptime
20:03 up 1:43, 2 users, load averages: 0.94 0.82 0.78
$
uptime tells you how long your server has been running. uptime also gives the average system load for the last few minutes. Use uptime for a quick performance check. Collect daily data to watch for problems from underpowered CPUs or memory management.
Coding example: I am making heavily documented and explained open source code for a method to play music for free — almost any song, no subscription fees, no download costs, no advertisements, all completely legal. This is done by building a front-end to YouTube (which checks the copyright permissions for you).

Create your own copy from the original source code/ (presented for learning programming).
