Initial git configuration
I’m setting up my new XPS 13 running Pop!_OS and one of the things I always have to do on any new machine is to configure git.
So, both for my own reference and in case it helps anyone else, here’s a list of things I do to set up git:
Set up my identity (used in commits, tags, etc.)
git config --global user.name "Aral Balkan" git config --global user.email email@example.com
Set up automatic signing of my commits
I sign my work and so should you (it’s about security, not vanity).
Either generate GPG keys if you don’t already have a pair or export/import your existing GPG keys.
Configure git to sign all your work:
git config --global commit.gpgsign true
You can check that it’s working by making a commit and then viewing at it in the log with the
git log -1 --show-signature
If you get a warning along the lines of WARNING: This key is not certified with a trusted signature! There is no indication that the signature belongs to the owner after importing your GPG key to a new machine, do the following (substituting your email address for mine):
gpg --edit-key firstname.lastname@example.org
Then, in the gpg shell, use the
trust command and select 5 = I trust ultimately.
Create ssh keys for the machine and import them into hosted git remotes like GitLab
In order to clone and push to git remotes using ssh, you have to create an ssh keypair and then upload it to your git remote (in my case, we use our own GitLab instance running on source.ind.ie).
Generate your ssh keys (substitute your email address for mine):
ssh-keygen -t rsa -C "email@example.com" -b 4096
Copy it onto the system clipboard.
cat ~/.ssh/id_rsa.pub | pbcopy
Note: On Linux, you can simulate the hugely useful pbcopy and pbpaste commands on macOS by adding the following to your .zshrc or .bashrc files:
alias pbcopy='xsel --clipboard --input' alias pbpaste='xsel --clipboard --output'
cat as the pager so that git commands do not use paging (I’d much rather scroll than switch modes.)
git config --global core.pager cat
That’s all I can think off at the moment. If I notice that I’ve left anything off, I’ll update the post accordingly.
If you have any initial configuration steps that you cannot live without, please let me know on Mastodon.
