Hi,

Is there a "p4 revert -a" equivalent in git or should I
whip up a script using git-diff-index and git-update-index?

That is I want to git-update-index --refresh for all
files whose inode may have changed but the actual file
data has not (i.e. git-diff-index is empty).

Thanks,
   Luben

```

That's what "git-update-index --refresh" does, unless I am
misreading what you say you want.

	$ git checkout master
        $ touch *.c
	$ git diff-index HEAD ;# tons of changes
        $ git update-index --refresh
	$ git diff-index HEAD ;# no changes

```

Ok, thanks.  I wasn't sure if I had to specify the file
names on the command line of "git-update-index --refresh".
It looks like I don't have to, so this is a perfect
equivalent.

Thanks,
   Luben
