git svn - GIT svn how to update a path -

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

TortoiseProc.exe / command: Updates / Path: "c: \ FoldToSVNRepository"
TurtleProtection.EXA / Command: Update / Path: "c: \ FoldToSVNRepositoryTwo"
ContosoProXA / Command : Updates / Path: "c: \ FoldToSVNRepositoryThree"

How will you work with the command equal? Git svn?

I have taken a look through the document but there is no way to specify the repository directory update.

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