Question

I would like to store all of my dotfiles on GitHub, including .gitconfig which requires me to hide the GitHub token in the .gitconfig.

To do so I have a “.gitconfig-hidden-token” file which is the file I intend to edit and put under git that hides the token:

...
[github]
user = giuliop
token = --hidden--
...

And a shell script which I need to launch if I modify the “.gitconfig-hidden-token” file to create the “.gitconfig” file:

cp .gitconfig .gitconfig.backup
sed 's/--hidden--/123456789/' .gitconfig-hidden-token > .gitconfig

The drawback is the need to manually launch the script everytime I modidy the file. Is there a better, fully automated way to do this?

Answer 1

Add your .gitconfig with git add -N.

Then git add -p it, edit the hunk, replace the token with anything, and push that. No need for an extra file this way.

Addendum: on additional modifications of your file, use git add -p again, and edit the hunk so that your initial manipulation not be overwritten.
