ローカルにクローンしたリポジトリのリモートURLを確認する方法はいくつあります。
リポジトリ例：
$ git clone git@github.com:ruby/ruby.git ruby
$ cd ruby
方法1
$ git config --get remote.origin.url
git@github.com:ruby/ruby.git
方法2
$ git remote -v
origin git@github.com:ruby/ruby.git (fetch)
origin git@github.com:ruby/ruby.git (push)
方法3
$ git remote show -n origin
* remote origin
Fetch URL: git@github.com:ruby/ruby.git
Push URL: git@github.com:ruby/ruby.git
HEAD branch: (not queried)
Local ref configured for 'git push' (status not queried):
(matching) pushes to (matching)
方法4
$ git remote show origin
* remote origin
Fetch URL: git@github.com:ruby/ruby.git
Push URL: git@github.com:ruby/ruby.git
HEAD branch: trunk
Remote branches:
ruby_1_3 new (next fetch will store in remotes/origin)
ruby_1_4 new (next fetch will store in remotes/origin)
....
方法5
$ cat .git/config
[core]
repositoryformatversion = 0
filemode = false
bare = false
logallrefupdates = true
symlinks = false
ignorecase = true
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = git@github.com:ruby/ruby.git
方法6
$ git config -l
...
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*
remote.origin.url=git@github.com:ruby/ruby.git
なお、git helpを活用すれば、何でも調査できる。例
$ git remote show --help
usage: git remote show [<options>] <name>
-n do not query remotes
