You mean
git diff HEAD^^ -- $file
git checkout HEAD -- $file
It's not $file, it is $path, and it is limiter. git-cat-file (the name
is certainly historical artefact and it should be git-cat-object) doesn't
support limiters.

Everything where you have <object> or <tree-ish> you can use colon
syntax. For example:
$ git ls-tree pu:Documentation
$ git grep -e --merge next:Documentation
$ git diff v1.4.2:gitweb/gitweb.cgi gitweb/web:gitweb/gitweb.perl
