David, Thanks for the helpful reply. As you suggested, I modified the .gitconfig file to have: [difftool "test"] cmd = echo \"$LOCAL\" \"$REMOTE\" and ran $ git difftool -t test An example of the the resulting console output is: C:/Users/Paul/AppData/Local/Temp/I8L2Bc_WriteTestParameters.vi Commands/StartAutomatedTest/WriteTestParameters.vi Paul -----Original Message----- From: David Aguilar [mailto:davvid@xxxxxxxxx] Sent: Friday, February 21, 2014 3:38 AM To: Paul Lotz Cc: git@xxxxxxxxxxxxxxx Subject: Re: difftool sends malformed path to exernal tool on Windows On Mon, Feb 17, 2014 at 03:14:01PM -0700, Paul Lotz wrote: > From the Git Bash command line, I enter $ git difftool > > and type ‘y’ when the file I want to difference appears.

If this is the case then difftool is not the only one with this problem. We use the GIT_EXTERNAL_DIFF mechanism to run difftool under "git diff", so it may be that the paths are mangled by "git diff" itself. I don't really know enough about msysgit to know for sure, though. What do you see if you create a dummy tool which just does "echo"?

Do any msysgit folks know whether GIT_EXTERNAL_DIFF is a known issue? -- David -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
