Git

Git is a revision control system that allows you to clone complete software repositories among developers.

Get git

Here is an example how to download and install git. Find out your distribution and proceed accordingly:

SLES 11

Get the SLE SDK media, add it as repository, install git using

yast -i git

SLES 10

This example downloads version 1.7.6 of git and must be executed as root user under a default installation of SLES 10:

• Download git

wget http://www.kernel.org/pub/software/scm/git/git-1.7.6.tar.gz

• if this does not work, you may have to set your proxy and redo it like this

export http_proxy=proxy.company.com:8080
wget http://www.kernel.org/pub/software/scm/git/git-1.7.6.tar.gz

• unpack it

tar xvzf git-1.7.6.tar.gz

• make sure you have all needed dependencies like this:

yast -i zlib-devel python-devel

• build it

cd git-1.7.6/
./configure && make -j8 && make install

• test it by calling

# git version
git version 1.7.6

svn co branch	git checkout branch	get a special branch of a software. Remark: This downloads additional code in the case of SVN, but not in the case of GIT.
svn up	git pull	update to the latest version
svn revert	git checkout .	revert the changes you have done
svn co -r commit	git reset commit	get the code as it was at a certain commit. Remark: This downloads additional code in the case of SVN, but not in the case of GIT.
