Install Git offline without sudo
I found a solution that works. To iterate my steps:
1) Download relevant RPM (or here)
2) Copy to Linux server and upack using (replace filename as necessary)
rpm2cpio git-1.7.9.6-1.el6.rfx.x86_64.rpm | cpio -idmv
3) Update $PATH:
PATH=$PATH:<your path to git>/usr/bin
4) Now see it work
git --version
