Multiple SSH Keys settings for different github account

Multiple SSH Keys settings for different github account =================================================================

create different public key
---------------------------------

create different ssh key according the article [Mac Set-Up Git](http://help.github.com/mac-set-up-git/)

 $ ssh-keygen -t rsa -C "your_email@youremail.com"

Please refer to [github ssh issues](http://help.github.com/ssh-issues/) for common problems.

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


Modify the ssh config
---------------------------------

 $ 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 you repo and modify your Git config
---------------------------------------------

clone your repo
 git clone git@github.com:activehacker/gfs.git gfs_jexchan

cd gfs_jexchan and modify git config

 $ git config user.name "jexchan"
 $ git config user.email "jexchan@gmail.com" 
 
 $ git config user.name "activehacker"
 $ git config user.email "jexlab@gmail.com" 

or you can have global git config
 $ git config --global user.name "jexchan"
 $ git config --global user.email "jexchan@gmail.com"


then use normal flow to push your code

 $ git add .
 $ git commit -m "your comments"
 $ git push
