1. 实验环境介绍

给出实验环境：

操作系统：Linux kali Debian 8.x.64
平台：VMware 15

2. 常用命令使用

1、创建文件

2、删除、复制文件或者更改目录

3、修改文件里面内容

保存后存在

4、ping自己主机

3. 剖析ps命令

运行man ps，将ps使用方法拷贝过来，比如：

Usage:
ps [options]

Basic options:
-A, -e               all processes
-a                   all with tty, except session leaders
a                   all with tty, including other users
-d                   all except session leaders
-N, --deselect       negate selection
r                   only running processes
T                   all processes on this terminal
x                   processes without controlling ttys

Output formats:
-F                   extra full
-f                   full-format, including command lines
f, --forest         ascii art process tree
-H                   show process hierarchy
-j                   jobs format
j                   BSD job control format
-l                   long format
l                   BSD long format
-M, Z                add security data (for SELinux)
-O <format>          preloaded with default columns
O <format>          as -O, with BSD personality
-o, o, --format <format>
                      user-defined format
s                   signal format
u                   user-oriented format
v                   virtual memory format
X                   register format
-y                   do not show flags, show rss vs. addr (used with -l)
     --context        display security context (for SELinux)
     --headers        repeat header lines, one per page

Usage:
ps [options]

Selection by list:
-C <command>         command name
-G, --Group <GID>    real group id or name
-g, --group <group> session or effective group name
-p, p, --pid <PID>   process id
        --ppid <PID> parent process id
-q, q, --quick-pid <PID>
                      process id (quick mode)
-s, --sid <session> session id
-t, t, --tty <tty>   terminal
-u, U, --user <UID> effective user id or name
-U, --User <UID>     real user id or name

The selection options take as their argument either:
a comma-separated list e.g. '-u root,nobody' or
a blank-separated list e.g. '-p 123 4567'
