To have a releavant git config for different repos, use includeIf (for condition on remote url git version must be >= 2.46.0 )
Example with Remote URL#
You’ve got multiple ssh keys for a host user1.gh and user2.gh:
Host user1.gh
HostName github.com
User user1
IdentityFile ~/.ssh/github/user1/id_ed25519
and you use ssh link as a remote url:git clone git@user1.gh:<user>/<repo>
to automate git configuration, create a config specific to this host, create a file like:~/gitconfigs/user1.gh.config
and put configuration you need there, like:
[user]
email = user1@email.net
signingkey = <key>
[commit]
gpgsign = true
and include this config to a global config (git config --global -e):
[includeIf "hasconfig:remote.*.url:git@user1.gh:*/**"]
path = /home/<user>/gitconfigs/user1.gh.config
verify if it has worked (in directory with relevant repo):git config --list --show-origin
conditional config should be shown.
