linux - 如何在windows中获取unix风格的提示符(批量)

Question

我正在尝试制作显示 unix/linux 提示符的 dos shell。代码是:

@echo off
:hi
set tmpdrv=%cd:~0,2%

if %homedrive% == %tmpdrv% (
  set drvmatch=1
) else (
  set drvmatch=0
)
set "MYSTRING=abcdef!%%^^()^!"
set MYSTRING=%homepath%
:strlen
(echo "%MYSTRING%" & echo.) | findstr /O . | more +1 | (set /P RESULT= & call exit /B %%RESULT%%)
set /A STRLENGTH=%ERRORLEVEL%-5
set tmppath1=%cd:~2%
CALL set tmppath2=%%tmppath1:~0,%STRLENGTH%%%
if %homepath% == %tmppath2% (
  set homematch=1
) else (
  set homematch=0
)

set homepathmatch=0
if %homepath% == %tmppath2% (
    if %homedrive% == %tmpdrv% (
    set homepathmatch=1
    )
)

if %homepathmatch%==1 (
    REM set /a STRLENGTH=%STRLENGTH%+2
        CALL set newpath=%%tmppath1:~%STRLENGTH%%%
    set newpath1=~%newpath%
)
set newpath2=%newpath1:\=/%
:check_Permissions

 net session >nul 2>&1
 if %errorLevel% == 0 (
 set "username2=root"
 ) else (
 set username2=%username%
 )
set /p %command%="%username2%@%computername%:%newpath2%$ "
%command%
goto :hi

我希望它像 unix/linux 中一样显示目录名称，但它显示一个 ~。我的代码有什么问题？你能帮我改进一下吗？

可能不太清楚提示特定情况的子字符串修改，但设置提示的方法是。

@ECHO OFF & Setlocal EnableDelayedExpansion & TITLE %~n0
cls & MODE 1000 & CD %userprofile%\desktop


    For /F "tokens=* Delims=\" %%A In ("%userprofile%") Do (
        Set "C_Prompt=%%A"
        Set "C_Prompt=!C_Prompt:\=!"
        Set "C_Prompt=!C_Prompt:Users=!"
    For %%A in (a,b,c,d,e,f,g,h,i) Do (Set "C_Prompt=!C_Prompt:%%A:=!")
    )
    Set DirPath=:!CD:\=/!
    For %%A in (a,b,c,d,e,f,g,h,i) Do (Set "DirPath=!DirPath:%%A:=!")
    Set "C_Prompt=!C_Prompt!@!computername!!DirPath! $$ "

prompt !C_Prompt!

Start /B cmd.exe

上面的内容不会刷新工作目录的命令提示符，但会导致命令按预期运行，而不会出现扩展问题。

This linked Macro will refresh the Prompt when the working Directory changes, however the act of expanding commands within a user defined variable can result in unexpected results.
