Git is a revision control system that allows you to clone complete software repositories among developers.
Contents
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
How to ...
... get a past version
repository # git reset c3c9e4d97f0668235a5b Unstaged changes after reset: M README
git vs svn translation
| svn | git | purpose |
|---|---|---|
| svn co | git clone | get the software |
| 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. |
