why git?
why git? diffs
why git? diffs backups
why git? diffs backups collaboration
what git can do for you versioning easy collaboration blame
tracking down bugs safe experimentation statistics
what github can do for you issue-tracking even easier collaboration
remote backups access your files from anywhere graphical, easy-to-use UI
now: how git works
repository directory on filesystem just metadata (changes) manual grouping of
changes
commit group of logically-related changes 1 or more files (add/delete/modify)
staging index CHANGES I WANT IN MY NEXT COMMIT ALL
THE OTHER CHANGES
git commit -m 'test' CHANGES I WANT IN MY NEXT
COMMIT ALL THE OTHER CHANGES a new commit, with message 'test'
CHANGES I WANT IN MY NEXT COMMIT ALL THE OTHER
CHANGES the commit with message 'test' (nothing here yet)
your computer REMOTE REPOSITORIES LOCAL REPOSITORY some server another server
github
now: git tips
rebasing git rebase -i [start commit] reorder, reword, edit, squash
commits
amending git commit --amend staged changes become part of previous
commit
force pushing git push origin master -f useful after amending/rebasing
multiple remotes git remote add origin [url] git remote add
upstream [different URL] useful when pulling from other developers
patch git add --patch stage one chunk at a time
diffing git diff (unstaged) git diff --cached (staged) git diff
--check (whitespace errors)
colours git config --global color.ui auto
fix your whitespace git stripspace git apply --whitespace=fix
good commit messages Fix bug (50 chars max, capitalised, imperative)
Longer description explaining what the commit does. Wrap at 72 characters. Don't forget the blank line. bit.ly/gitcommit
bisect git bisect (or, "when did this bug first appear?")
ignoring .gitignore (untracked files) git update-index --assume-unchanged (tracked files) git
status --ignored
better pulls git pull vs git fetch & git merge
aliases git s = git status git add = git
add --patch git ds = git diff --staged git amend = git commit --amend git say = git commit -m git un = reset --soft HEAD^1
fixing merge conflicts 1. Don't panic 2. git status 3.
Look for the <<< 4. Stage & commit
moving files git mv [source] [destination] instead of: mv [source]
[destination] git rm [source] git add [destination]
sensitive data help.github.com/articles/remove-sensitive-data
selective staging git add --update (only tracked files) git add
--all (all files)
view configuration git config --list
pushing to remotes git push origin master git push origin
localbranch:remotebranch git push origin :remotebranch (deletes it)
branch tracking git push origin master -u git push origin
local:remote -u
stashing edits git stash git stash apply git stash pop
(applies, then removes from stack)
fixing mistakes git checkout (undo edits) git reset --soft (keeps
edits) git reset --hard (loses edits)
merge strategies git merge --strategy=[strategy] strategies: recursive (default), ours, theirs,
etc
now: github tips
keyboard shortcuts press ? to bring up the help
issues in commits "Fix #54" -> closes issue #54 from
the commit "For #54" -> links to #54 from commit, & vice versa
all from your browser edit, commit, send a pull request
... all without leaving your browser
blame who introduced this line, and when, and why
file rendering markup, geoson, csv, and more
integration with travis continuous integration (automated testing)
