df -h >> /tmp/linux_output.txt
egrep -i "err|fault|mysql" /var/log/* >> /tmp/linux_output.txt

git init
git add index.html
git commit -m"my first commit"
git diff
git clone public_html my_website

# git log
git status
git log
git show xxx
git diff xxx

## branching out
git branch
gi branch dev
git show-branch --more=5
git checkout dev
git checkout HEAD index.html
git merge dev
git diff
git reset --mixed HEAD^
git reset --hard ORIG_HEAD
git branch -d dev

## add shortcuts
git config --global alias.show-graph 'log --graph --abbrev-commit --pretty=online'

## plumbing commands
git ls-files --stage
git ls-files --unmerged
git cat-file -p xxx
