用于处理字符串文件的Windows批处理

Question

我使用以下代码来确定文件的第二行是否有字符串(::echo1、：：echo3 2和：：echo3 3)。但是，当我出于某种原因在for命令中IF命令的子例程:_verify中运行代码时，它会完全跳过IF的else部分，这会增加变量%chk%并返回到:_verify，这反过来会增加它在文件中查找的::echo的数量，并再次搜索同一个文件(它需要在每个文件中搜索所有3个)。我尝试将IF命令反转为IF，并将else切换为最前面，将call :_redeem放在最后，但同样的错误也发生了。(注意:对于包含：：Echo1的文件，它确实正确地完成了:_verify调用)。它只检查每个文件的：：eco1，因为它不会增加%chk%并再次转到:_verify。相反，它直接转到goto :eof并返回到:identify来查找另一个文件，它将再次查找该文件，只处理::echo1。我添加了一些注释来帮助解释我的脚本。

set gt1=1
setLocal EnableDelayedExpansion
::Identifies all files meeting the criteria (name being tmp*.tmp) and sets cap%gt1% equal the filename. Also checks to see if there are no files left (if the filename doesn't exist (i.e. it's blank because there are none left)).
:identify
set chk=1
if %gt1%==4 goto :restore
for %%A in (tmp*.tmp) do (set cap%gt1%=%%A) & call :_verify 
if not exist !cap%gt1%! goto :error
goto :identify

:_verify
::Verifies that the specific file it's looking at (set as cap%gt1% in :identify) has the string ::echo1, 2 or 3 as the second line.
if %chk%==4 call :_reserve & goto :eof
for /f "skip=1" %%B in (!cap%gt1%!) do if %%B==::echo%chk% (call :_redeem) else (set /a chk=%chk%+1) & (goto :_verify)
goto :eof

:_redeem
::Renames files that are confirmed to have the string to their string name (minus the ::).
ren !cap%gt1%! echo%chk%.tmp
set /a gt1=%gt1%+1
goto :eof

:_reserve
::Subroutine used to temporairly discard files that do not meet the requirements so they will not be processed again in :identify during loopback.
if not exist temp50 mkdir temp50
move !cap%gt1%! temp50
goto :eof

:restore
::Restores files that were put in :_reserve to their previous location.
if exist %~dp0\temp50 cd temp50 & for %%C in (tmp*.tmp) do move %%C %~dp0 & cd .. & rmdir temp50
pause

:error
::Error in case it can't find all three files containing the strings.
echo Unable to find program files. Please reinstall.
echo.
pause
quit

而不是

，它直接转到goto :eof

情况就是这样，因为您编写代码就是为了这样做。

你想写

if %chk%==4 (call :_reserve & goto :eof)

但是你的代码是这样工作的

if %chk%==4 call :_reserve
goto :eof

你应该避免使用&分隔符，最好使用带括号的多行。

for %%A in (tmp*.tmp) do (
   set cap%gt1%=%%A
   call :_verify 
)
....
if %chk%==4 (
   call :_reserve
   goto :eof
)
