[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%system32wbemwmic 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!"
)
