[工作笔记]几个常用的字符串处理脚本, 标记一下.

//从abc;bdcd;sdf;sefs字符串中分别获取abc bdcd sdf sefs等字符串

//从abc;bdcd;sdf;sefs字符串中分别获取abc bdcd sdf sefs等字符串

for %%i in (%path%) do (

    set tmpStr=%%i

    echo !tmpStr!

)

 

//以上方法无法修改Path, 2K3下可测修改Path的方式

@echo off

::==========>>>添加/删除系统Path变量的指定内容<<<==========

::开启延时加载

setlocal enabledelayedexpansion

set pathContent=%1

set opType=%2

::echo !pathContent!

::

::echo PATH=%path%

if not "!pathContent!"=="" (

    set tmpStr=

    set pathStr=

    for %%i in (%path%) do (

        set tmpStr=%%i

        if {!tmpStr!} NEQ {!pathContent!} (

            set pathStr=!pathStr!!tmpStr!;

        )

        if {!opType!}=={/add} (

            set pathStr=!pathStr!!pathContent!;

        )

    )

    set pathStr=!pathStr:~0,-1!

::WMIC首次使用会占用一定的初始化时间, 以下会永久改变path

%windir%\system32\wbem\wmic ENVIRONMENT where "name='path' and username='<system>'" set VariableValue="!pathStr!"

::以下这个只能临时改变Path，不能永久改变

set path="!pathStr!"

)

exit /b
