Trees, Branches, and Blobs

git init
git add *
git commit -m 'hello git'


init, clone

git init
git clone git://...

status, add, diff

tracked/untracked "staged"

file status lifecycle, p. 20 gitbok

git status

Add a file called ".gitignore" to ignore "temporary" or other files you don't want to track.

*.[oa]
*~
*.pyc


git diff

Shows changes to unstaged files only

git diff --cached

Show what you've staged so far

commit

git commit -m 'added new quote'
git commit -a -m 'edited links'

Stages every file (that's being tracked) -- ie "auto add"

git commit --amend

Add forgotten changes to last commit.

rm

git rm readme.txt
git rm --cached readme.txt

Remove from the stage, but not the file! (untrack)

git mv

(technically git "sees" these movements already, same as mv, remove, add: but the command is there for convenience)

log

git log
git log -p -2
git log --stat
git log --pretty=oneline
git log --graph

remote

git remote
git remote -v
git add remote remote-name URL

Where remote-name is whatever you want it to be called, and the URL is a remote git URL.

git remote show origin
git fetch remote-name

pull

pull = fetch + merge

push

git push [remote-name] [branch-name]
git push origin master

tags

Show SMW ?!

Auto-Completion

contrib/completion/git-completion.bash

Add to .bashrc:

source ~/.git-completion.bash

(or)

cp git-completion.bash /etc/bash_completion.d/

(linux)

cp git-completion.bash /opt/local/etc/bash_completion.d/

(mac)

branch

git checkout -b iss53

create + checkout a branch, short for:

git branch iss53
git checkout iss53
git checkout master
git checkout -b fix
git commit -a -m 'fixed something'
git checkout master
git merge fix
git branch -d fix

"Fast-forward" reflects that the changes were "upstream" of the current working state.


conflict

Generally, you want to commit all your changes before switching branches (checkout)


If we each write to master -- lots of conflicts? Contrast with creating branch for each person ?!
