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...
list_for_each_entry(fmt, &formats, lh) 指令的作用就是遍历所有加载器,并调用 load_binary 回调函数,看是否能找到一种加载器可以处理保存在 bprm 中的文件。也就是执行 execve 系统调用传入的文件,在 do_execveat_common->prepare_binprm 函数中,读取了当前可执行文件的前 128 字节到 bprm->buf 中,通过该...

This is a simplified list of the basic commands; you don’t need all of the details just yet. 现在让我们来看一些更多的Unix命令。以下大部分程序接受多个参数,并且有些命令有很多选项和格式,完整的列表是没有意义的。 这是一个简化的基本命令列表;你现在不需要所有的细节。
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...
8.1 Tracking Processes(追踪进程) You learned how to use ps in 2.16 Listing and Manipulating Processes to list processes running on your system at a particular time. The ps command lists current processes, but it does little to tell you how processes change over time. Therefore, it won’t re...
