Launch exe from Ruby

[melmoth]

Hi all,
it’s my first post here, so I hope I’m in the right place to ask.
I’m using Ruby for implementi a simple script, I have problem when I
want to launch an exe with as argument a path with spaces:
something like

command = "mediainfo C:\folder1\another folder\file.mp4 "
IO.popen(command)

If there’s a space in the path it doesn’t work

command = "mediainfo C:\folder1\file.mp4 "
IO.popen(command)

This works,
is there something I’m missing?

Thanks a lot for any reply
Bye

I don’t use Windows, so I can’t be sure, but I think I read somewhere
you need
to quote the path inside the string:

command "mediainfo "C:\folder1\another folder\file.mp4 “”

If you don’t want have to escape the " inside the string, you can
enclose it
in single quotes, instead:

command ‘mediainfo "C:\folder1\another folder\file.mp4 "’

I hope this helps
