我有一个包含许多svg文件的文件夹，我想使用inkscape和批处理脚本(Windows 10 *.bat 文件)将它们转换为png文件.以下脚本对于单个文件正确运行，但是，如何对目录中的数百个文件重复相同的命令?

I have a folder containing many svg files and I would like to convert them to png files using inkscape with a batch script (Windows 10 *.bat file). the following script works correctly for a single file but, how to iterate the same command for hundreds of files inside a directory?

PATH = "C:\Program Files\Inkscape" inkscape myfile.svg --export-png=myfile.png

推荐答案

@echo off for %%i in ("%~dp0*.svg") do ( echo %%i to %%~ni.png "C:\Program Files\Inkscape\bin\inkscape" --export-type="png" "%%i" )

要通过利用所有逻辑内核来加快处理速度，可以使用以下多任务处理方法:并行执行Shell进程

To speed things up by utilizing all of your logic cores, you can use this multitasking approach: Parallel execution of shell processes

@echo off setlocal enableDelayedExpansion :: Define the command that will be run to obtain the list of files to process set listCmd=dir /b /a-d "%~dp0*.svg" :: Define the command to run for each file, where "%%F" is an iterated file name from the list :: something like YOUR_COMMAND -in "%%F" -out "%%~nF.ext" set runCmd=""C:\Program Files\Inkscape\bin\inkscape" --export-type="png" "%%F"" :: Define the maximum number of parallel processes to run. set "maxProc=%NUMBER_OF_PROCESSORS%" ::--------------------------------------------------------------------------------- :: The remainder of the code should remain constant :: :: Get a unique base lock name for this particular instantiation. :: Incorporate a timestamp from WMIC if possible, but does not fail if :: WMIC not available. Also incorporate a random number. set "lock=" for /f "skip=1 delims=-+ " %%T in ('2^>nul wmic os get localdatetime') do ( set "lock=%%T" goto :break ) :break set "lock=%temp%\lock%lock%_%random%_" :: Initialize the counters set /a "startCount=0, endCount=0" :: Clear any existing end flags for /l %%N in (1 1 %maxProc%) do set "endProc%%N=" :: Launch the commands in a loop set launch=1 for /f "tokens=* delims=:" %%F in ('%listCmd%') do ( if !startCount! lss %maxProc% ( set /a "startCount+=1, nextProc=startCount" ) else ( call :wait ) set cmd!nextProc!=%runCmd% echo ------------------------------------------------------------------------------- echo !time! - proc!nextProc!: starting %runCmd% 2>nul del %lock%!nextProc! %= Redirect the lock handle to the lock file.
