Use Nohup to Run a Task in the Background Let’s now see how you can use the nohup command to run a process in the background. Note that the ping command is used for demonstration purposes only. We strongly advise not to use it because it can consume resources and slow down system p...

由于假设我们只有一个终端接口,因此在可以出现提示字符让你操作的环境就称为前景 (foreground),至于其他工作就可以让你放入背景 (background) 去暂停或运作。要注意的是,放入背景的工作想要运作时, 他必须不能够与使用者互动。 举例来说, vim 绝对不可能在背景里面执行 (running) 的!因为你没有输入数据他就不会跑...

★普通进程(Normal Process):又称为分时进程,这类进程在Linux系统中遵循默认的分时调度策略,如CFS(Completely Fair Scheduler)。它们按照各自权重(nice值)和虚拟运行时间(vruntime)来获取CPU时间片。nice值可以在[-20, 19]范围内调整,数值越小,优先级越高,但总体来说,普通进程之间是公平共享CPU资源的。 ★实时进...
Processes—the running programs that the kernel manages—collectively make up the system’s upper level, called user space. (A more specific term for process is user process, regardless of whether a user directly interacts with the process. For example, all web servers run as user processes.)...
2.16.4 Background Processes(后台进程) Normally, when you run a Unix command from the shell, you don’t get the shell prompt back until the program finishes executing. However, you can detach a process from the shell and put it in the “background” with the ampersand (&); this gives ...
