ssh git configuration

ssh configuration can be tricky with git if you have to use multiple keys and even more so when multiple keys
for the same host. This post will demonstrate a flexible configuration method of defining git configuration
per top level directory.

in ~/.gitconfig put the following

[includeIf "gitdir:~/code/"]
    path = ~/.gitconfig.d/personal

[includeIf "gitdir:~/work/"]
    path = ~/.gitconfig.d/work

This includes .gitconfig.d/personal if you are in ~/code and .gitconfig.d/work if you are in ~/work

Within each of these files you can then configure the appropriate things for that space

[core]
sshCommand = "ssh -i ~/.private/keys/personal/secret"

[user]
email = user@example.net
name = sigmonsays

the sshCommand parameter sets what private key to use for the ssh connection. The other
parameters configure what e-mail and name to use for committing.

That’s about it!
