GIT svn how to update a path

When using svn, I update a repository with the following command.

TortoiseProc.exe /command:update /path:"c:\FoldToSVNRepository"

TortoiseProc.exe /command:update /path:"c:\FoldToSVNRepositoryTwo"

TortoiseProc.exe /command:update /path:"c:\FoldToSVNRepositoryThre开发者_高级运维e"

How would you do the equivilant with the command

git svn ?

I've had a look through the documentation but cannot find any way to specify the repository directory to update.

git --git-dir=C:\repo\.git svn fetch
