create different ssh key according the article Mac Set-Up Git
$ ssh-keygen -t rsa -C "[email protected]"
for example, 2 keys created at:
~/.ssh/id_rsa_activehacker
~/.ssh/id_rsa_jexchan
then, add these two keys as following
$ ssh-add ~/.ssh/id_rsa_activehacker
$ ssh-add ~/.ssh/id_rsa_jexchan
you can delete all cached keys before
$ ssh-add -D
finally, you can check your saved keys
$ ssh-add -l
$ cd ~/.ssh/
$ touch config
$ subl -a config
Then added
#activehacker account
Host github.com-activehacker
	HostName github.com
	User git
	IdentityFile ~/.ssh/id_rsa_activehacker
#jexchan account
Host github.com-jexchan
	HostName github.com
	User git
	IdentityFile ~/.ssh/id_rsa_jexchan
clone your repo git clone [email protected]:activehacker/gfs.git gfs_jexchan
cd gfs_jexchan and modify git config
$ git config user.name "jexchan"
$ git config user.email "[email protected]" 
$ git config user.name "activehacker"
$ git config user.email "[email protected]" 
or you can have global git config $ git config --global user.name "jexchan" $ git config --global user.email "[email protected]"
then use normal flow to push your code $ git add . $ git commit -m "your comments" $ git push
