Warning, starting with git 2.0.X/2.1 (Q3 2014), git diffall will always return "command not found": it has been removed.

See commit 502b0a1 by Jonathan Nieder (jrn) (with the assistance of Tim Henigan (thenigan)):

contrib: remove git-diffall

The functionality of the "git diffall" script in contrib/ was incorporated into "git difftool" when the --dir-diff option was added in v1.7.11 (ca. June, 2012).
Once difftool learned those features, the diffall script became obsolete.

The only difference in behavior is that when comparing to the working tree, difftool copies any files modified by the user back to the working tree when the diff tool exits.
"git diffall" required the --copy-back option to do the same.
All other diffall options have the same meaning in difftool.

Make life easier for people choosing a tool to use by removing the old diffall script. A pointer in the release notes should be enough to help current users migrate.
