Is there a way to prune remote branches?

[gaogao-qwq]

My working gitlab repository will automatically remove the branches that are already merge into main branch. I couldn't found a keybind of prune remote branches, thus I have to run git remote prune origin manually.

I usually have this config option:

$> git config remote.origin.prune true

And then you can go to the Remotes panel and just fetch origin.

Or create a custom command to run git remote prune <currently selected remote>.

I recommend to do git config --global fetch.prune true. This way, remote branches are pruned automatically whenever you type git fetch or git pull on the command line; it also works in lazygit.

Luka's answer should also work, but needs to be configured for each remote separately.
