Use `git -C $dir $command` to change the directory before executing the
command. If you run `git clone $source $dest` a second time it will tell
you that the directory $dest is not empty and abort.

To start with git the first chapters of the git-book[1] are good. I'd
recommend to read at least the three first chapters for the beginning.
The rest is also very well written.

git along

[Ray Andrews]

Gentlemen,

The 'git' manual being longer than War and Peace, let me ask
some simple questions:

       git clone git:where-its-coming-from where-its-going-to

... simple. If I rerun it with the same target dir, will it just
update, or will it do the full monty all over again? Would any
files I've added be preserved, or nuked?

Or do we:

     git update ...

Can we:

     git just-show-me-whats-changed ... ?

... or is life just not meant to be so painless?

Is there a recommended beginner's guide to git?

This is really more suitable for zsh-workers, but to keep the thread in
one place:

There's a section on "Use of Git" in Etc/zsh-development-guide which has
pointers to additional help.

You don't want to clone again.  Use "git pull".

} Would any files I've added be preserved, or nuked?

I don't believe git will ever nuke something that's not under its control,
but I've never done a clone on top of a clone.

} Can we:
} 
}      git just-show-me-whats-changed ... ?

git status  -- to see what files are (not) under git control

git diff  --  to see what *you* changed but did not yet commit

git whatchanged  -- to see change history of your current source tree

git whatchanged origin/master  -- for changes you may not have "pull"ed

Just change into where-its-going-to and

git pull

or if you're liable to have made changes to the repository yourself since you last updated

git pull --rebase

which puts your changes together with the remote ones together in a neater
fashion.

Do you mean what you just imported in the last pull?

git log ORIG_HEAD..

Add the option -p if you want to see changes within files as a patch.

(As you're about to see, any sufficiently complicated git post
instantly has half a dozen git experts falling over themselves to point
out the error of your ways.)

  Thanks all for help with 'git'. Some nice docs there. Got a whole new 
set of words to
learn.

I'd recommend using tig [1] for this, which is very nice for digging through git 
logs. I guess that just about every distro has it.
