+## 前言
+
+​ 每当获取一个命令执行，但是服务器不出网，不能进行远程下载，或者写木马有限制，命令长度也有限制的苛刻条件下，可使用该工具进行木马分割，一键生成写入命令和合并或者追加命令写入木马；
+
+​ windows在苛刻条件下也可以分段写入文本，再合并写入二进制文件，具体可以与Certutil配合，将二进制文件转换为txt，再分段写入后合并还原二进制文件；
+
+## 功能介绍
+
+```
+-f string
+ 指定分割的文本
+-n int
+ 设置长度进行切割，默认32 (default 32)
+
+```
+
+只有两个功能：
+
+​ 1、根据文件后缀进行分割：
+
+```
+当文件是txt时，会直接分割成几个txt
+./Split_tools -f 1.txt
+
+当文件是木马后缀时，会分割后生成写入命令
+./Split_tools -f 1.jsp
+```
+

+
+​ 2、可设置分割的长度
+
+```
+./Split_tools -f 1.txt -n 64
+```
