使用示例:script.cmd echo Z: Y: W:
@echo off
:: u is a variable containing all arguments of the current command line
set u=%*
:: enabledelayedexpansion: exclamation marks behave like percentage signs and enable
:: setting variables inside a loop
setlocal enabledelayedexpansion
:: parsing result of command subst
:: format: I: => C:\foo\bar
:: variable %G will contain I: and variable H will contain C:\foo\bar
for /f "tokens=1* delims==> " %%G IN ('subst') do (
set drive=%%G
:: removing extra space
set drive=!drive:~0,2!
:: expanding H to a short path in order not to break the resulting command line
set subst=%%~sfH
:: replacing command line.
call set u=%%u:!drive!=!subst!%%
)
:: parsing result of command net use | findstr \\ ; this command is not easily tokenized because not always well-formatted
:: testing whether token 2 is a drive letter or a network path.
for /f "tokens=1,2,3 delims= " %%G IN ('net use ^| findstr \\') do (
set tok2=%%H
if "!tok2:~0,2!" == "\\" (
set drive=%%G
set subst=%%H
) else (
set drive=%%H
set subst=%%I
)
:: replacing command line.
call set u=%%u:!drive!=!subst!%%
)
call !u!
