Linux is a free and open source Unix-like operating system that uses the Linux kernel. There are many different Linux distributions that can be installed on a wide variety of computer hardware devices, from phones, tablets, routers and video game consoles, to desktop computers, large computers and supercomputers. Linux is a leading operating system, and the world 's fastest computing supercomputer is running Linux operating systems. LinuxThe operating

1.Terminal (terminal)The Linux system also provides a program called Terminal Emulator (Terminal), the following several more common terminal simulators, such as Gnome-terminal,kconsole,xterm,rxvt,kvt,nxterm and Eterm, At present, the terminal program in our experiment is the xfce-terminal that comes with XFCE desktop environment. It is important to note, however, that there is a difference between the terminal (Terminal) and the console (consoles).On

' is started at the corresponding runlevel.The init command begins by sending the/etc/rc.d/init.d/ The starting order of each symbolic link file is determined by the number behind ' K ' or ' S '. The lower the number, the sooner it starts. If the numbers are the same, they are started sequentially in the order of the letters following the numbers. We can determine the order in which the service or process starts by modifying the size of the number.Note: One of the last files of the INIT program

-known Apache server monitoring process.The KILL command works by sending a system operation signal to the kernel of the Linux system and the process identification number of a program, and then the system kernel can operate on the processes specified by the process identification number. For example, in the top command, we see that the system runs many processes, and sometimes it needs to use kill to abort some processes to improve system resources.

Tmux (full name is Terminal multiplexer) is an excellent end-use software, similar to GNU screen, but from OpenBSD, with BSD licensing. The most intuitive benefit of using it is that when you log in to a remote host through a terminal and run Tmux, you can open multiple consoles in it without having to "waste" redundant terminals to connect to the remote host, which is much more than that. Advantages over screen: You can split the windows horizontally
