Multiple github accounts on the same computer?

Question

Trying to work on my both my actual \"work\" repos, and my personal repos on git hub, from my computer.

The work account was set up first, and everything works flawl

Answer 1

I use shell scripts to switch me to whatever account I want to be "active". Essentially you start from a fresh start, get one account configured properly and working, then move the these files to a name with the proper prefix. From then on you can use the command "github", or "gitxyz" to switch:

# my github script
cd ~/.ssh

if [ -f git_dhoerl -a -f git_dhoerl.pub -a -f config_dhoerl ]
then
    ; 
else 
    echo "Error: missing new files"
    exit 1
fi 

# Save a copy in /tmp, just in case
cp id_rsa /tmp
cp id_rsa.pub /tmp
cp config /tmp
echo "Saved old files in /tmp, just in case"

rm id_rsa
rm id_rsa.pub
rm config
echo "Removed current links/files"

ln git_dhoerl id_rsa
ln git_dhoerl.pub id_rsa.pub
ln config_dhoerl config

git config --global user.email "dhoerl@.com"
git config --global github.user "dhoerl"        
git config --global github.token "whatever_it_is"

ssh-add -D

I've had great luck with this. I also created a run script in Xcode (for you Mac users) so it would not build my project unless I had the proper setting (since its using git):

Run Script placed after Dependencies (using /bin/ksh as the shell):

if [ "$(git config --global --get user.email)" != "dhoerl@.com" ]
then
    exit 1
fi

EDIT: added tests for new files existence and copying old files to /tmp to address comment by @naomik below.
