Pulling down somebody's fork with Git.
To provide an easy to use way to pull down somebodys fork on your project.
To pull down somebody's fork on your github project is kind of annoying. Its one of those things you dont do often, and when you do, you usually consult StackOverflow which is what I did here.
Accepted answer:
git remote add theirusername [email protected]:theirusername/reponame.git
git fetch theirusername
git checkout -b mynamefortheirbranch theirusername/theirbranchWow....thats annoying. The fact I have to specify their name 3 times is a hassle. So what I like to do for obscure annoying commands is turn them into a Bash function.
I called it
git-fork-pull im sure there are 1000 other things I could've called it, but naming is hard.The next step is to write how I want the function to work. I imagine I want to do something like the following:
git-fork-pull reponame theirname theirbranch mybranchSeems pretty straightforward to me. 4 positional arguments. I usually like keyword arguments, but theyre a little more tedious in Bash since they require an option parser like this https://unix.stackexchange.com/questions/129391/passing-named-arguments-to-shell-scripts .
Besides, this is only going to be used by me so im fine with it.
To make use of these 4 positional arguments, our function would look like this:
git-fork-pull() {
reponame="$1"
theirname="$2"
theirbranch="$3"
mybranch="$4"
}With the arguments in place, its not important to look at functionality. The functionality is fairly straightforward. We add the remote, fetch it, and then create a new branch based on their branch. To do this in our function, we'd continue on like this:
git-fork-pull() {
reponame="$1"
theirname="$2"
theirbranch="$3"
mybranch="$4"
git remote add "$theirname" "[email protected]:$theirname/$reponame.git"
git fetch "$theirname"
git checkout -b "$mybranch" "$theirname/$theirbranch"
}Now obviously this implementation is github specific, so you may have to look into supporting other sites like Gitlab or Bitbucket, but I'll leave this as an exercise for the reader.
If youre curious on how to autoload bash functions, heres what I do in my
.zshrc to load all bash functions.I have a
.zsh/functions directory full of files like git-fork-pull . So heres what a minimal source script looks like in your .bashrc or .zshrc to source all your custom functions.# .zshrc
CUSTOM_FUNCTIONS="$HOME/.zsh/functions"
for function in "$CUSTOM_FUNCTIONS"/*; do
source $function
donethis will interate over all files in your
~/.zsh/functions directory and source them for use by zsh. This could look identical in a .bashrc as well and using ~/.bash/functions.28
