Problem in running the Windows start command with exec.Cmd

[Hariharan Srinath]

Hi,

I'm trying to open a file in Windows 7 with its default program using the start command using Go 1.3 stable windows/amd64

On the Windows command line, when i type the following, it works perfectly:

cmd /c start "" "c:\some path\with spaces\in it\thefile.pptx"

However, if i try to run the following in Go, I get an popup alert box from Windows saying - "Windows cannot find `\\`. Check the spelling and try again, or try searching for the item by clicking the Start button and then clicking Search".

cmd := exec.Command("cmd", "/c", "start \"\" \"c:\\some path\\with spaces\\in it\\thefile.pptx\"")

err := cmd.Start()

if err != nil {

fmt.Println(err)

}

This also gives the same error:

cmd := exec.Command("cmd", "/c", `start "" "c:\\some path\\with spaces\\in it\\thefile.pptx"`)

I'm guessing what's being run by exec.Cmd is not equivalent to what i typed on the Windows command line. Any pointers to what i'm doing wrong?

Best Regards

Sorry - typo in my second example. I meant that backquoted string without double slashes was also giving the same error:

cmd := exec.Command("cmd", "/c", `start "" "c:\some path\with spaces\in it\thefile.pptx"`)

try

      cmd := exec.Command("cmd", "/c", "start", "", `c:\some path\with spaces\in it\thefile.pptx`)

Yup - this worked! Thanks Dave!
