The default git diff behavior is to open each diff file in serial 
(wait for previous file to be closed before opening next file).

I'm looking for a way to open all the files at once - in BeyondCompare 
for example this would open all the files in tabs within the same BC window.

This would make it easier to review a complex set of changes; 
flick back and forwards between the diff files and ignore 
unimportant files.

Here's my same question on StackOverflow with a couple of ideas 
I have found (copy files to temp dir and do folder diff, Araxis 
has 'nowait' option):

I posted the script below on IRC the other week[1] in reply to someone
looking for a way to do this for 'meld'.  I'm not sure this is the
*fastest* way to do this, but I'm at least trying to take a few
shortcuts ;-)

Since this is now the second request for such a tool, it would be nice
if you could at least shape this as a contrib/ patch (if it fits your
needs, of course).

Thanks Thomas, I'll take a few days to digest/test this 
(I'm new to bash and git) and give feedback.

Just realised I never posted my solution. This works great for me, I wouldn't do 
without it:

Thanks.  We should add git difftool --all, what do you think?

Do you have any thoughts about difftool's defaults?
I've always kind of felt that --no-prompt was a possible candidate...

I've come up with a simple script that diffs the files in a background task:

  for name in $(git diff --name-only $1); do git difftool $1 $name & done

Then aliased the script for usage:

  git diffall [--staged]

Being a bash newbie, I'd appreciate any feedback on what seems to be 
a simple solution...??
