行首行末添加字符串

实际应用场景：
	我们现在有一个只有cmd功能的system权限的windows shell
	主机为xp 32位，3389处于打开状态，我们想使用ew将其3389端口代理出来，但是xp既没有bitsadmin有没有certutil，我们可以选择使用vbs脚本进行下载，这时我们就需要通过echo命令来将vbs脚本的内容写入到目标主机的一个文件中，如果手动一行一行地使用echo命令写入，实在是太麻烦了，我们可以借助sed强大的文本处理功能，在原来的vbs的每一行的行首和行尾加上“echo ”和“>>%temp\update.vbs%”，首先将vbs内容写到test中，然后执行下面两条命令，复制test中的内容，直接粘贴到我们的cmd shell上，一次性执行完所有的写入命令，最后再执行cscript.exe %temp%\update.vbs即可
	
		sed -i 's/^/&echo /g' test
		sed -i 's/$/& >>%temp%\\update.vbs/g' test
		
	第二条命令中多出来的反斜杠为转义符

搜索当前目录中的所有文件，查找指定字符串

​ 应用场景，调试PHP时，寻找某一字符串是由哪一个文件输出的
​

	grep -nr "print" *
		r选项代表递归（查询子目录）
		*代表所有文件

截取字符串

应用场景：
​ 现在我要从一份泄露的邮箱账户中截取出密码，形式如下：
​ aaa@qq.com:test

​ 我需要截取出:后面的字符串

只需要使用下面这条命令即可：

​

var="aaa@qq.com:test"
echo ${var#*:}

获取子串在母串中的偏移量

​ echo $a | grep -bo ":" | sed 's/:.*$//'

grep -bo ":"打印样式匹配所位于的字符或字节偏移，如果不使用sed进行处理，会把我们要匹配的字符也跟在后面，并使用:分割，因此我们需要使用sed的正则匹配，将:以及:之后的所有字符替换成空

反转字符串

​ echo str | rev

剔除含有某一字符串的行

​ sed -i '/keywords/d' filename

提取出包含某一字符串的行

​ sed -n '/keywords/p' filename

JS提取域中的主机

我们使用dsquery导出的计算机结果基本上是对下面这个样子：

"CN=CR-50,OU=Coumputers_CR,DC=domain,DC=com"
"CN=CR-55,OU=Coumputers_CR,DC=domain,DC=com"
"CN=CR-54,OU=Coumputers_CR,DC=domain,DC=com"

我们可以使用下面这个脚本，将主机名提取出来：

var str = `
"CN=CR-50,OU=Coumputers_CR,DC=domain,DC=com"
"CN=CR-55,OU=Coumputers_CR,DC=domain,DC=com"
"CN=CR-54,OU=Coumputers_CR,DC=domain,DC=com"
`


str.trim().split('\n').forEach(function(v, i) {
var result = /.*?"CN=(.*?),.*?/.exec(v);
document.write(result[1]);
document.write("</br>");
})

这样就可以在浏览器中输出主机名了

文本处理

然后用该脚本测试那些主机可以联通：

@echo off

setlocal ENABLEDELAYEDEXPANSION 

for /f %%i in (dn.txt) do (
	echo %%i
	net use \\%%i\ipc$ "password" /user:cotoso.com\administrator >>temp.tmp 2>&1
	for /f %%l in ('type temp.tmp ^| find /i "1326" /c') do ( 
        if %%l equ 1 (
			echo %%i>>res.txt )
	)
	del temp.tmp
)

使用JS从任意字符串中提取出IP地址

正则表达式：

(\d{1,3}\.){3}\d{1,3}

\d{1,3}\.表示匹配一个1~3个数字组成的字符串和一个.

d和.元字符需要转义所有前面的那个\，这个是正则的基础语法，不需要我多解释

将它们用()括起来，作为一个匹配模式，后面的{3}表示该匹配模式要重复3次，最后再跟上一个\d{1,3}，由1~3个字符组成的数字

这样就能匹配到所有符合IP地址特征的字符串了

使用JS实现，代码如下：

var str = `
172.96.244.114  testsetsetset   testsetsetset    testsetsetset  testsetsetset104.224.181.204     asdasdasd   testsetsetset    testsetsetset  testsetsetset67.230.185.196  testsetsetset   testsetsetset    testsetsetset    testsetsetset104.224.144.160     testsetsetset   testsetsetset    asdasdasd                    testsetsetset104.224.182.250     testsetsetset   testsetsetset    testsetsetset             testsetsetset104.224.190.79  testsetsetset testsetsetset     2oixMlMlzAPPkUxt    testsetsetset   testsetsetset95.163.207.244  testsetsetset   testsetsetset    syi71eRZiehv                    testsetsetset172.96.241.42   testsetsetset   testsetsetset    testsetsetset  testsetsetset198.181.40.163  testsetsetset   testsetsetset    testsetsetset  testsetsetset104.224.178.144     testsetsetset   testsetsetset    testsetsetset  testsetsetset104.224.177.150     testsetsetset   testsetsetset    testsetsetset  testsetsetsetasdasdas
`
var result = str.match(/(\d{1,3}\.){3}\d{1,3}/g);
for ( var i = 0; i <result.length; i++){
	document.write(result[i]);
	document.write("<br />");
}
