Listing processes in LinuxTo list processes in Linux, use one of the five commands: ps, top, htop, atop, and pstree. Each command offers different detail and output formats. For instance, ps provides a momentary view of all processes, while top and htop dynamically sort them by CPU usage...
The /proc directory contains information about currently running processes as well as some kernel parameters. o /sys This directory is similar to /proc in that it provides a device and system interface. You’ll read more about /sys in Chapter 3. o /sbin The place for system executables. ...
Recall from Chapter 1 that a process is a running program. Each process on the system has a numeric process ID (PID). For a quick listing of running processes, just run ps on the command line. You should get a list like this one: 回顾一下第一章,进程是正在运行的程序。系统上的每个进...

Services or daemons are Linux programs that run in the background. System administrators must understand how to manage services to maintain their server’s functionality and performance. The commands to list services differ depending on the Linux init system. Systemd service listing usessystemctl, wh...
当我们执行一个可执行程序的时候, 内核会list_for_each_entry遍历所有注册的linux_binfmt对象, 对其调用load_binrary方法来尝试加载, 直到加载成功为止. execve加载可执行程序的过程 内核中实际执行execv()或execve()系统调用的程序是do_execve(),这个函数先打开目标映像文件,并从目标文件的头部(第一个字节开始)读入...

In particular, you’ll learn how to connect streams to files and other processes. 标准流的一个最好的特性是你可以轻松地操作它们以读取和写入除终端以外的其他地方,你将在2.14 Shell输入和输出中学到这一点。特别是,你将学习如何将流连接到文件和其他进程。
Additionally all of the processes in the system are held in a doubly linked list whose root is theinitprocessestask_structdata structure. This list allows the Linux kernel to look at every process in the system. It needs to do this to provide support for commands such aspsorkill. ...
