Imagine the next situation:
- You have only one laptop
- You have your personal GitHub account
- Your employer stores code on GitHub as well
- You need to commit your personal code to your personal repositories but also work code to the employer`s repositories.
- You can`t do this from your personal account but do not want to create an additional one (with corporate email)
What to do in this situation? There is a way, how you can configure your laptop to commit to work repositories with work credentials, and to personal one with your personal one.
This solution is based on 2 aspects:
- correcting SSH config
- git URL re-writing
The main advantage of this approach is that it doesn't require any additional work to get it right. You will not need to change remote URLs or remember to clone things differently. The second part ( the URL rewriting) will take care of it.
First of all, let's correct our .ssh config. Assuming you have 2 ssh keys, your personal (
github_personal) and your work (
github_work). How to create ssh keys you can read in the GitHub docs.
Host github.com HostName github.com User git IdentityFile ~/.ssh/github_personal # Work GitHub Host github-work HostName github.com User git IdentityFile ~/.ssh/github_work Host * AddKeysToAgent yes
Both this configs have same user and domain, but we will take care about it later. Next - global git config.
Here we need to add our default name and email (the one we used in ssh creation for our personal account)
[user] name = My Name email = email@example.com [includeIf "gitdir:~/path/work_dir/"] path = ~/path/work_dir/.gitconfig [url "github-work:work-github-org-name/"] insteadOf = firstname.lastname@example.org:work-github-org-name/
What happens here? First, set our default name and email. Second, we point to use local
.gitconfig file for all repositories located by mask
~/path/work_dir/. And the last, replace
github.com (default account for Github) with the profile we set under
The last part is modification of local
.gitconfig for all our working repositories:
It is easy - just replace your email with your corporate one.
[user] email = email@example.com
That is all! As long as you keep all your work repos under
~/path/work_dir/ and personal stuff elsewhere, git will use the correct SSH key when doing pulls/clones/pushes to the server, and it will also attach the correct email address to all of your commits.
How to check? Clone repository via SSH, cd to that folder and execute
git config --get user.email

This is super handy! Very well explained!
Thanks a lot!
Thanks. What if you have 1 using GitHub and 1 using GitLab?
I'm guessing it's the same principle.
No difference, but you will need to replace
insteadOfpart with url pattern from GitLab (assuming this one is work)
Very cool, I'm still a command line type person and having this would be great when I want to do some personal stuff but keep it in my own repos.
GUI clients like GitKraken also make this ridiculously easy
IF you use GUI clients)
In my case, I am "one IDE" kinda guy, so I have terminal and VS Code. )
But thanks for the comment!
Works like a charm.
Just make sure to change the
remote "origin"url in the
okay. You could've explained it better but...
So what you're saying is: you make those ssh files and in each project you create a .gitconfig and when you go all git add . / git commit -m"smthing" git push origin smthing .... IT WILL go to the correct repos?
OR you have to chnage your config email and username for each add/pull/push?
No, sir. Sorry for that, will try to explain better.
You do this once:
If you do clone, pull, push inside this repo, you will use WORK account automatically (no need to switch or any other things, just
If you clone/push/pull outside this repo - it will use PERSONAL account
So you dont need to modify gitconfig for every working repo. as long as you have
thanks, I usualy change .git/config? to add multiple branch, like github and azure
