英文:
CMD script: copy a file and rename it
问题
以下是您提供的 CMD 脚本的翻译：
@echo off
echo 源路径
set /P folder1=
echo 文件名
set /P file1=
echo 目标路径
set /P folder2=
if %folder1% == %folder2% goto path
if exist %folder2%\%file1% goto exist
set file2=%file1%
set "file2=%~dpn1_copy%~x1"
copy %folder1%\%file1% %folder2%\%file2%
goto end
:exist
echo 文件存在于目标文件夹中
goto end
:path
echo 目标路径和源路径相同
goto end
:end
请注意，我已经移除了代码部分的翻译，只提供了您要求的翻译好的部分。如果您需要进一步的帮助，请随时告诉我。
英文:
I have to write a simple CMD script, its task is to copy a file from one folder to another. User have to enter source and destination path and the name of the file. Script has to add "_copy" to the name of copied file. I only know how to add a suffix to the file after file extension but it's not what I need.
I was trying it with %~n1 and %~x1 but it didn't work properly. Can someone help me solve this problem?
@echo off
echo Source path
set /P folder1=
echo File name
set /P file1=
echo Destination path
set /P folder2=
if %folder1% == %folder2% goto path
if exist %folder2%\%file1% goto exist
set file2=%file1%
set "file2=%~dpn1_copy%~x1"
copy %folder1%\%file1% %folder2%\%file2%
goto end
:exist
echo File exist in destination folder
goto end
:path
echo Destination and source paths are the same
goto end
:end

%1 (输入的第一个参数) 从未被设置，您需要设置它。在这种情况下，使用 call 来设置它。
@echo off
set /p "sourcep=源路径："
set /p "sourcef=文件："
set /p "destp=目标路径："
if "%sourcep%" == "%destp%" echo 源和目标路径相同 & goto :EOF
if exist "%destp%\%sourcef%" echo %sourcef% 已经存在于 %destp% & goto :EOF
call :work "%sourcef%"
goto :EOF
:work
if not exist "%destp%\%~n1_copy%~x1" (
copy "%~f1" "%destp%\%~n1_copy%~x1"
) else (
echo "%destp%\%~n1_copy%~x1" 已经存在
)
您也可以使用搜索/替换方法，但这将包括使用 delayedexpansion 或为变量添加一些转义：
@echo off & setlocal enabledelayedexpansion
set /p "sourcep=源路径："
set /p "sourcef= 文件："
set /p "destp=目标路径："
set "ext=%sourcef:*.=%"
set "file=!sourcef:.%ext%=!"
if "%sourcep%" == "%destp%" echo 源和目标路径相同 & goto :EOF
if exist "%destp%\%sourcef%" echo %sourcef% 已经存在于 %destp% & goto :EOF
if exist "%destp%\%file%_copy.%ext%" echo "%destp%\%file%_copy.%ext%" 已经存在 & goto :EOF
copy "%sourcep%\%sourcef%" "%destp%\%file%_copy.%ext%"
英文:
%1 (first argument from input) never get's set, you need to set it. In this case use call to set it.
@echo off
set /p "sourcep=Source path: "
set /p "sourcef=File: "
set /p "destp=Destination path: "
if "%sourcep%" == "%destp%" echo source and destination is the same & goto :EOF
if exist "%destp%\%sourcef%" echo %sourcef% already exists in %destp% & goto :EOF
call :work "%sourcef%"
goto :EOF
:work
if not exist "%destp%\%~n1_copy%~x1" (
copy "%~f1" "%destp%\%~n1_copy%~x1"
) else (
echo "%destp%\%~n1_copy%~x1" already exists
)
You can also use the search/replace method, but that would include either using delayedexpansion or by adding some escaping to your variables:
@echo off & setlocal enabledelayedexpansion
set /p "sourcep=Source path: "
set /p "sourcef= File: "
set /p "destp=Destination path: "
set "ext=%sourcef:*.=%"
set "file=!sourcef:.%ext%=!
if "%sourcep%" == "%destp%" echo source and destination is the same & goto :EOF
if exist "%destp%\%sourcef%" echo %sourcef% already exists in %destp% & goto :EOF
if exist "%destp%\%file%_copy.%ext%" echo "%destp%\%file%_copy.%ext%" already exists & goto :EOF
copy "%sourcep%\%sourcef%" "%destp%\%file%_copy.%ext%"
