问题：当我在DOS或Windows cmd shell的命令行中inputPATH时，我必须眯起眼睛看看是否包含我感兴趣的目录。 来自我的系统的示例：
PATH = C：\ ProgramData \ Oracle \ Java \ javapath; C：\ Program Files（x86）\ ActiveState Komo do Edit 9 \; C：\ Program Files（x86）\ NVIDIA Corporation \ PhysX \ Common; C：\ Python27 \ ; C：\ Program Files \ Common Files \ Microsoft Shared \ Windows Live; C：\ Program Files（x86）\ Common Files \ Microsoft Shared \ Windows Live; C：\ Windows \ system32; C：\ Windows; C：\ W C：\ Program Files（x86）\ IVI Foundation \ VISA \ WinNT \ Bin \; C：\ Program Files（x86）\ IVI Foundation \ VISA \ WinNT \ Bin; C：\ Program Files \ IVI Foundation \ VISA \ Win64 \ Bin \; C：\ PROGRA〜2 \ IVI Foundation \ VISA \ WinNT \ Bin; C：\ Program Files（x86）\ National Instruments \ Shared \ System \; c：\ Program Files（x86）\ Mic rosoft SQL Server \ 100 \ Tools \ Binn \; c：\ Program Files \ Microsoft SQL Server \ 100 \ Tool \ Binn \; c：\ Program Files \ Microsoft SQL Server \ 100 \ DTS \ Binn \ C：\ Windows \ System32 \ WindowsPowerShell \ v1.0 \; C：\ Program Files \ Internet Explorer; C：\ Program Files（x86）\ Calibre2 \; C：\ Program Files x86）\ Windows Live \ Shared; C：\ Program Files（x86）\ My SQL \ MySQL Utilities \; C：\ Prog （x 86）\ Pinnacle \ Shared Files \ Filter \文件（x86）\ MySQL \ MySQL Utilities \ Doctrine扩展名为PHP \; C：\ Program Files（x86）\ Pinnacle \ Shared Files \ ; C：\ Program Files（x86）\ nodejs \; C：\ RailsInstall er \ Git \ cmd; C：\ RailsInstaller \ Ruby2.1.0 \ bin; C：\ RailsInstaller \ Ruby2.1.0 \ lib \ ruby \ gems \ 1.9 .1 \ bin; C：\ RailsInstaller \ DevKit \ bin; C：\ xampp; C：\ xampp \ bin; C：\ xampp \ mysql \ bin; C：\ Users \ Owner \ AppData \ Roaming \ npm
OUCH !!
来吧 – 那么多的代码？
echo %path:;=&echo/% 或者为一个文件：
(for %%i in ("%path:;=";"%") do @echo(%%~i)>cleanpath.txt
并作为奖金：
echo %path:;=&echo/%|sort
要么
(for %%i in ("%path:;=";"%") do @echo(%%~i)|sort>cleanpath.txt
解决方案：批处理文件，每行打印一个目录到控制台。 作为奖励，它还将相同的输出打印到当前目录中的文件中。
@echo off setlocal EnableDelayedExpansion @echo off set "str=%PATH%" REM unREM this next line to see the raw PATH output REM echo %str% REM use substr to replace every ';' with (the equivalent of) ';\n' set "CleanPath=%str:;=;&echo.% " echo. echo %CleanPath% echo. set LF=^ REM !! Above blank lines are important - DO NOT DELETE THEM !! REM Next, copy same clean path to a file, should it be desired. REM Quietly create a file if it does not exist. copy /y NUL CleanPath.txt >NUL FOR /F "tokens=* delims=;" %%i IN ("%str:;=!LF!%") DO echo %%i >> CleanPath.txt
结果：
