RE: File Systems and a Theory of Edits

[Michael Nahas <mike.nahas@gmail.com>]

Rene,
I don't doubt that there exists current commands in git that can
perform operations like cat, ls, etc.  My point is that git can make
it easier for new users to learn commands and existing users to
remember commands if git copies the name and sematics (as much as
possible) of cat, ls, etc.

Ævar,
The issue is what goes inside the xargs command.  If it is unix's cat
command, the files listed by find will be from the commit's snapshot,
but the files read by cat will be from the working tree.

I believe the solution for xargs may be John D.'s solution - to
"mount" the snapshot as a file system.  And the "mount" command in git
is "git checkout".  (Now, I almost want to rename "git checkout" to
"git remount"!)
