How to update Emacs git?

How to update Emacs git?

[Rodolfo Medina]

Hi all.

I downloaded and installed Emacs git with:

 $ git clone git://git.savannah.gnu.org/emacs.git
 $ cd emacs
 $ ./autogen.sh
 $ ./configure
 $ make
 # make install

.  Now, suppose I want to simply update it without downloading it all again.
What shall I do?

Thanks for any help,

Rodolfo

Hi,

probably, something like this will do what you want:

 $ cd emacs
 $ git pull
 $ ./autogen.sh
 $ ./configure
 $ make
 $ make install

`git pull' command will download only the changes, not whole repository.

The 2 marked commands are not really necessary, except after the
initial clone.  After that, just "make" will do (it will regenerate
the configure script and run it with the same arguments automatically,
if needed).

Good point! Thank you for this note.
