The git command-line utility has plenty of inconsistencies http://steveko.wordpress.com/2012/02/24/10-things-i-hate-about-git/
A GUI like http://sourcetreeapp.com is often helpful, but staying on the command line usually quicker. This is a list of the commands I use most frequently, listed by functional category:
git status					list which (unstaged) files have changed
git diff						list (unstaged) changes to files
git log						list recent commits
git add fn					stage file
git commit -m 'message'			commit file
git commit -am 'message'		add/commit all changes from all tracked files (no untracked files) in one go
http://git-scm.com/book/en/Git-Tools-Rewriting-History
git reset filename				unstage file
git commit --amend -m 'message'	alter the last commit (add any staged files, new comment)
git reset --soft HEAD^			undo previous commit, put changes in staging
git reset --hard HEAD^			Undo last commit and all changes
git reset --hard HEAD^^			Undo two (^^) last commits and all changes
git checkout -- cats.html index.html	Undo all changes that were made to files cats.html and index.html
git rebase --onto <commit-id>\^ <commit-id> HEAD	remove specific commit from repository. the \ in ^ is just an escape   char to make zsh play nice and is not necessary if using bash.
git remote add origin [email protected]:example/petshop.git add a remote repository
git push -u origin master			push current local repo to remote. -u sets it to default for the future
git remote -v show				show the available remote repositories that have been added
git pull						checkout and merge remote changes in one go
git fetch origin						update the local cache of the remote repository
git remote -v update				bring remote refs up to date (and -v show which branches were updated)
git status -uno will tell you whether the branch you are tracking is ahead, behind or has diverged. If it says nothing, the local and remote are the same.
git show-branch *master will show you the commits in all of the branches whose names end in master (eg master and origin/master).
git show remote origin			show local<->remote branch tracking and sync status
git fetch origin
git log HEAD..origin/master --oneline shows commit messages
git diff HEAD..origin/master shows all changes on remote compared to local HEAD
git branch						list currently existing branches
git branch [branchname]			create new branch
git checkout branchname			move to that branch
git checkout -b branchname			create and checkout new branch in one go
git branch -d branchname			remove branch
git checkout master; git merge branchname;	conditions for fast-forward merge - nothing new on master between branch start/end points
git fetch origin``git branch -r 		list remote branches (after a fetch)
git push origin :branchname		delete remote branch 'branchname'
git remote prune origin			clean up deleted remote branches (let's say someone else deleted a branch on the remote)
git remote show origin			show local<->remote branch tracking and sync status (duplicate info under "remote repositories")
git push heroku yourbranch:master       simple form
git push heroku-staging staging:master 	(localBranchName:remoteBranchName)
git tag	list all tags
git checkout v0.0.1	checkout code
git tag -a v0.0.3	-m 'Version 0.0.3'	add new tag
git push --tags	push new tags to remote
