批处理文件for循环，在dir名称中包含空格

Question

How do I modify this:

for /f %%a IN ('dir /b /s build\release\*.dll') do echo "%%a"

to work when the path contains spaces?

For example, if this is run from

c:\my folder with spaces

it will echo:

c:\my

Thanks

Answer 1

You need to use:

for /f "delims=" %%a IN ('dir /b /s build\\release\\*.dll') do echo "%%a"

This overrides the default delimiters which are TAB and SPACE

Answer 2

I got around this by prepending "type" and putting double quotes surrounding the path in the IN clause

FOR /F %%A IN ('type "c:\A Path With Spaces\A File.txt"') DO (
    ECHO %%A
)

This article gave me the idea to use "type" in the IN clause.

If you don't want to deal with "quotes" you can use the "s" switch in %~dpnx[]... this will output the short filenames that are easy to work with.

from the Command line...

for /f "delims=" %f IN ('dir /b /s "C:\Program Files\*.dll"') do echo %~sdpnxf

inside a .CMD/.BAT file you need to "escape" the [%] eg, double-up [%%]

for /f "delims=" %%f IN ('dir /b /s "C:\Program Files\*.dll"') do echo %%~sdpnxf
