Batch file Can';t将批处理脚本的参数正确传递到循环语句内的命令中
我在向脚本中的命令传递参数时遇到问题,脚本将在线流下载到单个目录,然后使用ffmpeg修复错误 首先,我检查目录是否存在,如果不存在,则创建一个:Batch file Can';t将批处理脚本的参数正确传递到循环语句内的命令中,batch-file,cmd,windows-scripting,Batch File,Cmd,Windows Scripting,我在向脚本中的命令传递参数时遇到问题,脚本将在线流下载到单个目录,然后使用ffmpeg修复错误 首先,我检查目录是否存在,如果不存在,则创建一个: if exist %1 ( echo Directory exists ) ELSE ( mkdir "%1%" echo Directory created ) 然后是一个主循环,它尝试下载流并修复其中的错误 for /L %%C in (1,1,10000) do ( streaml
if exist %1 (
echo Directory exists
) ELSE (
mkdir "%1%"
echo Directory created
)
然后是一个主循环,它尝试下载流并修复其中的错误
for /L %%C in (1,1,10000) do (
streamlink -o "%%1\%%1%%C.mp4" "some.url/%2" best
if exist %1\%1%C.mp4 (
d:\streamlink\ffmpeg\bin\ffmpeg.exe -loglevel debug -i "%1\%1%C.mp4" -c:v copy -c:a copy "%1\%1%C_o.mp4" 1>"%1%\log\%1%%C.log" 2>"%1%\err\%1%%C.err"
)
timeout /T 300
)
例如,如果我执行:
script.cmd foo xyz
然后,应在第一个循环中执行:
streamlink -o "foo\foo1.mp4" "some.url/xyz" best
if exist foo\foo1.mp4 (
d:\streamlink\ffmpeg\bin\ffmpeg.exe -loglevel debug -i "foo\foo1.mp4" -c:v copy -c:a copy "foo\foo1_o.mp4" 1>"foo\log\foo1.log" 2>"foo\err\foo1.err"
)
您能帮我解决这个问题吗?请打开,运行call/?

处理的批处理文件
我建议将此批处理文件用于任务,尽管我不知道for循环的真正作用
