我正在尝试将当前 git 分支名称放入 Windows 批处理文件中的变量中。为此，我尝试对“git branch”命令的输出中的每个分支进行 for 循环并搜索“*”。我认为我的实现中有一些细节阻碍了我成功，也许是 for 循环内部的细节？我下面有两个批处理文件，一个尝试使用，findstr另一个使用第一个字符的字符串比较。没有触发 if 语句，我认为它要么是变量赋值，要么是字符串比较的语法。
批处理文件 1（字符串比较）
SETLOCAL ENABLEDELAYEDEXPANSION
SET count=1
SET variable="foobar"
SET currentBranch
FOR /F "tokens=* USEBACKQ" %%F IN (`git branch`) DO (
SET var!count!=%%F
SET /a count=!count!+1
SET variable=%%F
SET result=%variable:~0,2%
IF "%result%"=="* " (
ECHO found current branch
SET currentBranch=%%F
) ELSE (
ECHO Not current branch
)
)
ECHO END
ECHO currentbranch=%currentBranch%
ECHO variable=%variable%
ECHO result=%result%
ENDLOCAL
pause
批处理文件 2 (findstr)
git branch | find "* master"| findstr /B * > NUL & IF ERRORLEVEL 1 (
ECHO I am NOT on master
) ELSE (
ECHO I am on master
)
SETLOCAL ENABLEDELAYEDEXPANSION
SET count=1
SET variable="foobar"
SET currentBranch
FOR /F "tokens=* USEBACKQ" %%F IN (`git branch`) DO (
SET var!count!=%%F
SET /a count=!count!+1
SET varz=%%F
%%varz|find "* " > NUL & IF ERRORLEVEL 1 (
ECHO I am NOT on currentBranch
) ELSE (
ECHO I am on current branch
SET currentBranch=%%F
)
)
ECHO END
ECHO currentbranch=%currentBranch%
ECHO variable=%variable%
ECHO result=%result%
ENDLOCAL
pause
答案1
您不需要整个程序来完成此操作。
@echo off
set current_branch=
for /F "delims=" %%n in ('git branch --show-current') do set "current_branch=%%n"
if "%current_branch%"=="" echo Not a git branch! && goto :EOF
echo The current branch is %current_branch%
归根结底git branch --show-current，您不需要解析结果。

以下是对上面错误批次的更正，我认为核心问题是没有使用 !variable! 语法进行动态扩展：
SET count=1
SET variable="bullshit"
SET result="bullshit"
SET currentBranch
FOR /F "tokens=* USEBACKQ" %%F IN (`git branch`) DO (
SET var!count!=%%F
SET /a count=!count!+1
SET variable=%%F
SET result=!variable:~0,2!
IF "!result!"=="* " (
ECHO found current branch
SET currentBranch=%%F
) ELSE (
ECHO Not current branch
)
)
SET currentBranch=!currentBranch:~2!
set Branch=!currentBranch!
