On the other hand I understand de data model of git and can't to the most basic shit without looking up which invocation I need via search engine/man pages. Like... deleting a branch `git branch -d` (-D for forced deletion). Deleting a remote? `git remote rm`. Knowing the model teaches me nothing about the ui.

This seems like a good opportunity to plug two aliases I wrote about a year ago that have been very helpful for cleaning up all the extraneous branches that would show up when I ran `git branch`.

I run `git listdead` after I merge and delete a branch and do the next fetch (`git pull --rebase`). That lists the branches that can now be deleted.

Then I run `git prunedead` and it actually removes them.

Previously if I ran `git branch` it would list every development branch I had ever created in nearly a decade of work. Now it lists maybe ten branches.

   listdead = "!sh -c \"git branch -vv | grep ': gone]' | awk '{print \\$1}'\""

   prunedead = "!sh -c \"git branch -vv | grep ': gone]' | awk '{print \\$1}' | xargs git branch -D\""

Myself, I frequently refer to the man pages, as well as StackOverflow.

I'm not sure if I'm missing some features in Vim or you're actually pulling my leg by forcing me to notice that I know more about text than I care to admin :-)

(I'm not OP, BTW, just a random passer-by)

The latter! Sorry, didn't mean to cause you to question your sanity.
