Question

I ran this command twice today, the second time to experiment with the quotes because the setting didn’t seem to have an effect:

git config --global difftool.vs2012.cmd "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe" -diff "$LOCAL" "$REMOTE"

Now when I run this:

git config --global --get difftool.vs2012.cmd

I get this:

C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe
error: More than one value for the key difftool.vs2012.cmd: C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe

Note the error.

Running git difftool -t vs2012 still doesn’t work, but my question is how to remove the apparent duplicate key-value pair in the Git config file somewhere?

While typing this question, I ran the first command again and I now seem to have it 3 times! Why does it keep adding more and more instead of overwriting?

And where is the config file so I can edit it using Notepad instead of this awful, awful command line syntax?

I thought Git was going to be good the way people bang on about it.

P.S. The following question doesn’t mention how to resolve it.

More than one value for the key user.name Git

Answer 1

To remove the duplicates, I had to edit .gitconfig in my home directory (Windows profile) in a text editor that honors the line-endings.

Git, being a Linux thing, and Linux people thinking that the way they do stuff is in God’s vision, they ignore the line-endings of the Windows platform they’re running on, so be careful not to mangle the file by using just any text editor on Windows.
