Running windows shell command

[dfaroi]

Hi all,

Sorry for my english, I'm french.

I have some problem running an xcopy command with paths that contains
spaces.
I'm trying that :
output = `cmd /c xcopy /r /y \"C:/Test A\" \"C:/Test B\"`

Xcopy doesn't return any error but don't transfer files from "Test A"
to "Test B".
If I rename those paths without spaces and double quotes, it works :
output = `cmd /c xcopy /r /y C:/TestA C:/Test B`

Could someone can explain this issue ?
Or can tell me a better way to do fast copy files under Windows and get
back a list of files tha was transfered ?

Copying files with ruby is less faster than running an xcopy command.
Is it always true ?

Thanks all for you're help to a french guy

You may be 'over-escaping'. You shouldn't need to escape double-
quotes in backticks. What happens if you do:
output = `cmd /c xcopy /r /y "C:/Test A" "C:/Test B"`

It's better than my french

I have some problem running an xcopy command with paths that contains
spaces.
I'm trying that :
output =3D `cmd /c xcopy /r /y \"C:/Test A\" \"C:/Test B\"`

As logan mentioned, you don't need to escape the double quotes.

You also don't need to call 'cmd /c', but you certainly can if you
like. I think that using it might actually hide the error, since
you're now getting the result of running 'cmd' and not of running
'xcopy'.

I _think_ the problem is the use of the '/' as the path separator. I
ran a few tests here, and it seems that can be interpreted by cmd as a
paramater flag (just as you are using the /c /r and /y flags). So try
changing the slash to backslash (which does need to be escaped) like
this:

output =3D `xcopy /r /y "C:\\Test A" "C:\\Test B"`

Thansk for your help Logan Capaldo and Bill Guindon.

Commercial license for using rsync is too expensive.
That's why i'm searching for an other way to perform same thing by
myself.

Any other idea ?

Do you think that it's the faster way to synchronize 2 directories ?
I'll very appreciate an expert advise.

Are you sure you can package rsync with a commercial product under GPL
license ?

 

[yeman13]

Thanks for the link. I will give a look this week end.

You can if:
1: It's not part of your work.
2: You redistribute the rsync code (or a written offert).
