A bash alias for intermediate git users: gityank
As a git user, every once in a while you'll be doing a git pull
and be blindsided by the following error:
git pull
There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details.
git pull <remote> <branch>
If you wish to set tracking information for this branch you can do so with:
git branch --set-upstream-to=<remote>/<branch> mybranch
So naturally, you groan.
Then proceed to copy/paste pieces of this enormous command, and maybe use shell auto-completion with something like zsh.
What if I told you there was a better way?
A while back I had to run this incantation several times every day while migrating a few git repos to different remotes. After 2 days of this madness, I had to create a bash function - and it's saved my sanity hundreds of times since then!
Without further adieu I present gityank
; when you cant pull, yank!
gityank() {
if [ "$#" -eq 0 ]; then
1="$(gb)"
elif [ "$#" -eq 1 ]; then
git branch --set-upstream-to="origin/$1" $1
else
git branch --set-upstream-to="$1/$2" $2
fi
}
The function itself is rather simple. The key is git rev-parse --abbrev-ref HEAD
, which determines the current branch.
In my bash profile, I actually have it aliased to gb
.
