第三十课：解决msfvenom命令自动补全

本课是针对前第1-20课时的msfvenom生成payload的自动补全命令补充。虽msfvenom强大，同样有着非常繁琐的参数，参数强大，意味着会增加工作效率，但它并不像MSF有命令补全功能，故本课吸取前20课经验，自动补全msfvenom的参数。

需要zsh的支持：

root@John:~# cat /etc/shells
# /etc/shells: valid login shells
/bin/sh
/bin/dash
/bin/bash
/bin/rbash
/usr/bin/screen
/bin/zsh
/usr/bin/zsh
/usr/bin/tmux
root@John:~# echo $SHELL
/bin/bash

复制附录A到~/.oh-my-zsh/custom/plugins/msfvenom文件夹下（注：没有msfvenom目录，创建即可）

root@John:~/.oh‐my‐zsh/custom/plugins/msfvenom# pwd
/root/.oh‐my‐zsh/custom/plugins/msfvenom
root@John:~/.oh‐my‐zsh/custom/plugins/msfvenom# ls
_msfvenom

编辑~/.zshrc文件：

root@John:~# nano ~/.zshrc

root@John:~# nano ~/.zshrc
root@John:~# cat ~/.zshrc
plugins=(msfvenom)

更新：

root@John:~# source ~/.zshrc

效果如下：

附录A：
