在DOS批处理脚本中将文件写入相对路径

发布于 2024-10-24 10:17:48 字数 811 浏览 9 评论 0原文

FOR %%f IN (*.wav) DO CALL :runthis "%%f"
rem del temp.wav tmpfile
GOTO :EOF

:runthis
set "outdir=%~p1\output\"
copy "%~1" "%outdir%%~1"

最后一个命令应该对当前目录中的所有 .wav 文件进行dosomthing，并输出到现有子目录“输出”，并保留原始文件名。知道我哪里出错了吗？

更新1：谢谢，修复了语法。我没有注意到 %pI 仅将 I 扩展为路径，没有仔细阅读。现在的问题是它用 "s 扩展

dosomething "11.wav" "\Users\t4\Desktop\Airlines\WavRepeaters\\outdir\"11.wav""

它应该类似于::

dosomething "11.wav" c:\Users\t4\Desktop\Airlines\WavRepeaters\outdir\11.wav

Update2: %~dp1 - 仅将 %1 扩展为驱动器号和路径，不带引号！

Referring to What is the best way to do a substring in a batch file? I think the below should work.

FOR %%f IN (*.wav) DO CALL :runthis "%%f"
rem del temp.wav tmpfile
GOTO :EOF

:runthis
set "outdir=%~p1\output\"
copy "%~1" "%outdir%%~1"

The last command is supposed to dosomthing to all .wav files in current directory and output to existing sub-directory "output" keeping the original filename. Any idea where I'm going wrong?

Update1: Thanks, fixed the syntax. I didn't notice that %pI expands I to path only, didn't read carefully. Now what's wrong is that it's expanded with the "s

dosomething "11.wav" "\Users\t4\Desktop\Airlines\WavRepeaters\\outdir\"11.wav""

It should be something like::

dosomething "11.wav" c:\Users\t4\Desktop\Airlines\WavRepeaters\outdir\11.wav

Update2: %~dp1 - expands %1 to a drive letter and path only, without the quotations!

主要问题似乎是参数的使用。

在 :runthis 中，您使用 %~pI，但没有任何 %I。
另一个陷阱是文件名中的空格，然后需要在文件名/路径周围加上引号。

经过一些改变，它应该可以工作

@echo off
FOR %%f IN (*.bat) DO CALL :runthis "%%~f"
rem del temp.wav tmpfile
GOTO :EOF

:runthis
set "outdir=%~p1\output\"
echo dosomthing "%~1" "%outdir%%~1"
goto :eof

The main problem seems to be the use of the parameters.

In :runthis you use the %~pI, but there isn't any %I.
Another pitfall are spaces in the filenames, then dosomething need quotes around the filename / path.

With some changes it should work

@echo off
FOR %%f IN (*.bat) DO CALL :runthis "%%~f"
rem del temp.wav tmpfile
GOTO :EOF

:runthis
set "outdir=%~p1\output\"
echo dosomthing "%~1" "%outdir%%~1"
goto :eof
