GIT_SVN_ID may be set in the environment or via the --id/-i switch to an
arbitrary identifier if you're tracking multiple SVN branches/repositories in
one git repository and want to keep them separate.  See git-svn(1) for more
information.
user@hostname:~/repositories/app$ 

It means that the ‘git’ command is available for further usage. In this context, it is for cloning source code application from SVN repository.

2. Using the appropriate address of SVN repository, type the following command to start cloning the source code :

git svn clone https://xxx.xxx.xxx directory_target
Description : 
git svn : Command for performing any operations related with SVN Repository  
clone : Parameter for initializing source code fetched.
https://xxx.xxx.xxx : URL of SVN Repository   
directory_target : Directory created to store the cloned source code

For an example, the following is the output of ‘git’ command execution. It is followed by ‘svn’ keyword as additional parameter :

user@hostname:~/repositories/app$ git svn clone http://xxx.xxx.xxx/myrepo/app/module/ module
Initialized empty Git repository in /home/user/repositories/app/module/.git/
Authentication realm: <http://xxx.xxx.xxx:80> My Repository
Password for 'user': 
...
...
...
Checked out HEAD:
  http://xxx.xxx.xxx/myrepo/app/module r160
...
user@hostname:~/repositories/app$

As shown in the above output, by default the user used for cloning will be the user executes the command. On the contrary, as for another example below it is totally different with the additional parameter –user :

user@hostname:~/repositories/app$ git svn --user myuser clone http://xxx.xxx.xxx/myrepo/app/module/ module
Initialized empty Git repository in /home/user/repositories/app/module/.git/
Authentication realm: <http://xxx.xxx.xxx:80> My Repository
Password for 'myuser': 
...
...
...
Checked out HEAD:
  http://xxx.xxx.xxx/myrepo/app/module r160
...
user@hostname:~/repositories/app$

If nothing goes wrong with the above process, the source code located in http://xxx.xxx.xxx/myrepo/app/module/ will be cloned in a folder named module.
