1.uname -a :查看软件版本
kali@kali:~$ uname -a Linux kali 5.4.0-kali4-amd64 #1 SMP Debian 5.4.19-1kali1 (2020-02-17) x86_64 GNU/Linux
2.查看和更换软件源：vim /etc/apt/sources.list
kali@kali:~$ vim /etc/apt/sources.list
3.更新软件（更新架构）：apt update
root@kali:~# apt update
4.更新软件（更新软件）：apt -y full-upgrade
root@kali:~# apt -y full-upgrade
5.查看可更新的包：apt list --upgradable
root@kali:~# apt list --upgradable
6.ls -rthla :按时间顺序排列列出所有文件的列表信息，大写以千字节显示，不是以字节显示
kali@kali:~$ ls -rthla total 128K drwxr-xr-x 3 root root 4.0K Apr 9 02:18 .. -rw-r--r-- 1 kali kali 3.4K Apr 9 02:18 .bashrc -rw-r--r-- 1 kali kali 3.5K Apr 9 02:18 .bashrc.original -rw-r--r-- 1 kali kali 220 Apr 9 02:18 .bash_logout lrwxrwxrwx 1 kali kali 5 Apr 9 02:18 .face.icon -> .face -rw-r--r-- 1 kali kali 11K Apr 9 02:18 .face -rw-r--r-- 1 kali kali 807 Apr 9 02:18 .profile -rw-r--r-- 1 kali kali 55 Apr 9 02:25 .dmrc drwx------ 3 kali kali 4.0K Apr 9 02:25 .local drwxr-xr-x 2 kali kali 4.0K Apr 9 02:25 Templates drwxr-xr-x 2 kali kali 4.0K Apr 9 02:25 Public drwxr-xr-x 2 kali kali 4.0K Apr 9 02:25 Downloads drwxr-xr-x 2 kali kali 4.0K Apr 9 02:25 Documents drwxr-xr-x 2 kali kali 4.0K Apr 9 02:25 Desktop drwxr-xr-x 2 kali kali 4.0K Apr 9 02:25 Music drwxr-xr-x 2 kali kali 4.0K Apr 9 02:25 Pictures drwxr-xr-x 2 kali kali 4.0K Apr 9 02:25 Videos drwx------ 5 kali kali 4.0K Apr 9 05:02 .mozilla drwxr-xr-x 3 kali kali 4.0K Apr 9 06:13 .wpscan -rw------- 1 kali kali 6.1K Apr 9 06:18 .xsession-errors.old drwx------ 3 kali kali 4.0K Apr 9 21:40 .gnupg -rw------- 1 kali kali 49 Apr 9 21:40 .Xauthority -rw------- 1 kali kali 1.5K Apr 9 21:40 .ICEauthority drwxr-xr-x 9 kali kali 4.0K Apr 9 21:41 .cache drwxr-xr-x 16 kali kali 4.0K Apr 9 22:22 . -rw------- 1 kali kali 837 Apr 9 22:22 .viminfo -rw------- 1 kali kali 539 Apr 9 22:35 .bash_history drwx------ 12 kali kali 4.0K Apr 9 22:35 .config -rw------- 1 kali kali 6.9K Apr 9 22:44 .xsession-errors
7.移除已经安装软件的安装包：apt autoremove -y
root@kali:~# apt autoremove -y
8.apt-get update:软件源的更新（vim /etc/apt/sources.list 编辑软件源配置文件后，用此命令更新软件源）
root@kali:~# apt-get update
9.使用python打开一个简易的网络访问服务：python -m SimpleHTTPServer 800
在哪个目录下执行此命令了，访问http://192.168.209.128:800/后就是哪个目录下的文件，此处访问的就是/etc/ssh目录下的文件
root@kali:/etc/ssh# python -m SimpleHTTPServer 800 Serving HTTP on 0.0.0.0 port 800 ...
10.关闭800端口：使用netstat -anp | grep 800查到相应的进程号，如下为1634，使用kill -9 1634杀死相应的进程即可
root@kali:/etc/ssh# netstat -anp | grep 800
tcp 6 0 0.0.0.0:800 0.0.0.0:* LISTEN 1634/python tcp 1 0 192.168.209.128:800 192.168.209.1:57779 CLOSE_WAIT - tcp 1 0 192.168.209.128:800 192.168.209.1:57778 CLOSE_WAIT - tcp 1 0 192.168.209.128:800 192.168.209.1:57786 CLOSE_WAIT - tcp 1 0 192.168.209.128:800 192.168.209.1:57787 CLOSE_WAIT - unix 3 [ ] STREAM CONNECTED 27800 847/dbus-daemon /run/user/1000/bus root@kali:/etc/ssh# kill -9 1634
11. ip addr:查看地址
root@kali:/etc/ssh# ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:0c:29:cd:74:8f brd ff:ff:ff:ff:ff:ff inet 192.168.209.128/24 brd 192.168.209.255 scope global dynamic noprefixroute eth0 valid_lft 1597sec preferred_lft 1597sec inet6 fe80::20c:29ff:fecd:748f/64 scope link noprefixroute valid_lft forever preferred_lft forever
