This 'forks' themd5sumprocess into background. You can now see CPU usage withtop: As you can see it is consuming almost 100% of CPU resources (given that we have one CPU core on this droplet). We can bring up this process to foreground usingfgand cancel it withCTRL+C: Limit CPU us...

Linux是一个多用户多任务的操作系统,多用户是指多个用户可以在同一时间使用计算机系统,多任务是指Linux可以同时执行几个任务,大多数系统都只有一个CPU和一个主存,但一个系统可能有多个二级存储磁盘和多个输入/输出设备。操作系统管理这些资源并在多个用户间共享资源,当用户提出一个请求时,好像计算机系统只被自己独自占用。
