Alternative Git configuration to automatically switch accounts depending on repo path:

Create a file ~/.config/git/config.user1 containing:

[url "github_username1:"]
    insteadOf = git@github.com:
Create a config.user2 file that's the same except with "github_username2".

In your main ~/.config/git/config file, tell Git to "include" one of the two files depending on which directory you're at:

[includeIf "gitdir:~/projects/"]
    path = ~/.config/git/config.user1

[includeIf "gitdir:~/src/work/"]
    path = ~/.config/git/config.user2
Now, whenever you're at ~/src/work/, cloning anything from git@github.com:[etc] will automatically rewrite the URL to github_username2:[etc].
