A question about changing remote repo name

[Dongas <dongas86@gmail.com>]

Hi ALL,

I'm running ubuntu 9.04 and the git coming along with it doesn't
support git remote rename command.
Below is the man page of it:
GIT-REMOTE(1)
                                        Git Manual

     GIT-REMOTE(1)

NAME
       git-remote - manage set of tracked repositories

SYNOPSIS
           git remote [-v | --verbose]
           git remote add [-t <branch>] [-m <master>] [-f] [--mirror]
<name> <url>
           git remote rm <name>
           git remote show [-n] <name>
           git remote prune [-n | --dry-run] <name>
           git remote update [group]
Note: There's no rename option.

So i need to change the remote name manually.

I tried modifying the .git/config file locally but it didn't work.

Could someone help tell how to do it?

Thanks

Regards
