the result with this option, which would apply the
deletion part but not addition part.
+--allow-binary-replacement::
+ When applying a patch, which is a git-enhanced patch
+ that was prepared to record the pre- and post-image object
+ name in full, and the path being patched exactly matches
+ the object the patch applies to (i.e. "index" line's
+ pre-image object name is what is in the working tree),
+ and the post-image object is available in the object
+ database, use the post-image object as the patch
+ result. This allows binary files to be patched in a
+ very limited way.

Normally a commit would identify a new "HEAD" state, and while git
doesn't care where you save the note about that state, in practice we
-tend to just write the result to the file `.git/HEAD`, so that we can

--port::
Listen on an alternative port.
*what* you are going to commit is without having to write a new tree
object and compare it that way, and to do that, you just do
- git-diff-index --cached $(cat .git/HEAD)
+ git-diff-index --cached HEAD
Example: let's say I had renamed `commit.c` to `git-commit.c`, and I had
done an "git-update-index" to make that effective in the index file.
"git-diff-files" wouldn't show anything at all, since the index file
matches my working directory. But doing a "git-diff-index" does:
- torvalds@ppc970:~/git> git-diff-index --cached $(cat .git/HEAD)
+ torvalds@ppc970:~/git> git-diff-index --cached HEAD
-100644 blob 4161aecc6700a2eb579e842af0b7f22b98443f74 commit.c
+100644 blob 4161aecc6700a2eb579e842af0b7f22b98443f74 git-commit.c
have not actually done a "git-update-index" on it yet - there is no
"object" associated with the new state, and you get:
- torvalds@ppc970:~/v2.6/linux> git-diff-index $(cat .git/HEAD )
+ torvalds@ppc970:~/v2.6/linux> git-diff-index HEAD
*100644->100664 blob 7476bb......->000000...... kernel/sched.c
ie it shows that the tree has changed, and that `kernel/sched.c` has is
So for example
- git-fsck-objects --unreachable $(cat .git/HEAD .git/refs/heads/*)
+ git-fsck-objects --unreachable HEAD $(cat .git/refs/heads/*)
will do quite a _lot_ of verification on the tree. There are a few
extra validity tests to be added (make sure that tree objects are

changes. To illustrate, suppose you start from what has been
commited last to your repository:
- $ JC=`cat .git/HEAD`
+ $ JC=`git-rev-parse --verify "HEAD^0"`
$ git-checkout-index -f -u -a $JC
You do random edits, without running git-update-index. And then
we did `ln -sf refs/heads/newbranch .git/HEAD`, and when we want
to find out which branch we are on, we did `readlink .git/HEAD`.
This was fine, and internally that is what still happens by

-or that does not have the `readlink(1)` command, this was a bit

advertised (horrors).
SYNOPSIS
--------

+'git' [--version] [--exec-path[=GIT_EXEC_PATH]] [--help] COMMAND [ARGS]
DESCRIPTION
-----------
-
-This is reference information for the core git commands.
-
+'git' is both a program and a directory content tracker system.
+The program 'git' is just a wrapper to reach the core git programs
+(or a potty if you like, as it's not exactly porcelain but still
+brings your stuff to the plumbing).
+
+OPTIONS
+-------
+--version::
+ prints the git suite version that the 'git' program came from.
+
+--help::
+ prints the synopsis and a list of available commands.
+ If a git command is named this option will bring up the
+ man-page for that command.
+
+--exec-path::
+ path to wherever your core git programs are installed.
+ This can also be controlled by setting the GIT_EXEC_PATH
+ environment variable. If no path is given 'git' will print
+ the current setting and then exit.
+
