Example
You can download a github repository with the git clone command:[sfux@eu-login-03 ~]$ git clone https://github.com/astropy/astropy.git Initialized empty Git repository in /cluster/home/sfux/astropy/.git/ remote: Counting objects: 111782, done. remote: Compressing objects: 100% (60/60), done. remote: Total 111782 (delta 34), reused 0 (delta 0), pack-reused 111722 Receiving objects: 100% (111782/111782), 49.05 MiB | 16.04 MiB/s, done. Resolving deltas: 100% (85075/85075), done. [sfux@eu-login-03 ~]$Please have a look at the git documentation for more information on the different git commands.

GPLv2Troubleshooting
Contrary to the login nodes, the compute nodes can not access the Internet directly. Therefore git will display an error message when you try to download a git repository as part of a batch job:[leonhard@e1130 ~]$ git clone https://github.com/astropy/astropy.git Initialized empty Git repository in /cluster/home/leonhard/astropy/.git/ error: Failed connect to github.com:443; Operation now in progress while accessing https://github.com/astropy/astropy.git/info/refs fatal: HTTP request failed [leonhard@e1130 ~]$
This problem can be solved by configuring your git proxy settings first:
[leonhard@e1130 ~]$ git config --global http.proxy http://proxy.service.consul:3128 [leonhard@e1130 ~]$ git config --global https.proxy http://proxy.service.consul:3128 [leonhard@e1130 ~]$ git clone https://github.com/astropy/astropy.git Initialized empty Git repository in /cluster/home/leonhard/astropy/.git/ remote: Counting objects: 111782, done. remote: Compressing objects: 100% (60/60), done. remote: Total 111782 (delta 34), reused 0 (delta 0), pack-reused 111722 Receiving objects: 100% (111782/111782), 49.05 MiB | 12.84 MiB/s, done. Resolving deltas: 100% (85075/85075), done. [leonhard@e1130 ~]$
The global proxy configuration of git can be unset by the following commands:
git config --global --unset http.proxy git config --global --unset https.proxyYour current git settings are stored in the file $HOME/.gitconfig.
