I don't often need to contribute patches to code hosted on github; most of the projects I contribute to are either old school and don't use github for anything but mirroring their main git repo, or are small projects I entirely maintain so I don't submit pull-requests.
But when I do need to submit patches, github's hub tool makes my life a lot simpler, which allows forking repositories and submitting pull-requests very easily from the command line.
The 'hub' tool wants to be installed as an alias for 'git'. I originally tried that, but it made my bash prompt insanely slow since I show the current git branch and dirty state in my bash prompt. When I first encountered this, I filed a bug against the hub tool (with a bogus workaround), and nowadays it seems they have a disclaimer in their README.
Their recommended fix is to
s/git/command git/g in git-prompt.sh, which doesn't work too well if you use the linked fedora suggestion of pointing at the package installed file in /usr/share, so I avoid the alias. You can run 'hub' standalone, but instead I like to do:
sudo dnf install hub ln -s /usr/bin/hub /usr/libexec/git-core/git-hub
Then I can
git hub fork and
git hub pull-request all I want :)
