Setting up SourceGear DiffMerge for Git.md

1. Download SourceGear DiffMerge: http://sourcegear.com/diffmerge/index.html

2. Add the following to your global .gitconfig file:

    [diff]
        tool = DiffMerge
    [difftool "DiffMerge"]
        cmd = 'C:/Program Files/SourceGear/Common/DiffMerge/sgdm.exe' "$LOCAL" "$REMOTE"
    [merge]
        tool = DiffMerge
    [mergetool "DiffMerge"]
        cmd = 'C:/Program Files/SourceGear/Common/DiffMerge/sgdm.exe' -merge -result="$PWD/$MERGED" "$PWD/$LOCAL" "$PWD/$BASE" "$PWD/$REMOTE"
        trustExitCode = true
    [mergetool]
        keepBackup = false
   

After following these steps, you can run git difftool and git mergetool to open SourceGear DiffMerge from the Git Bash prompt.

This also works fine according to : https://gist.github.com/mkchandler/2377564
[diff]
tool = diffmerge
[merge]
tool = diffmerge
[difftool "diffmerge"]
cmd = 'C:/Program Files/SourceGear/Common/DiffMerge/sgdm.exe' "$LOCAL" "$REMOTE"
[mergetool "diffmerge"]
cmd = 'C:/Program Files/SourceGear/Common/DiffMerge/sgdm.exe' -merge -result="$PWD/$MERGED" "$PWD/$LOCAL" "$PWD/$BASE" "$PWD/$REMOTE"
trustExitCode = true
keepBackup = false
