how to commit

git commit

but before we commit...

...ALWAYS diff!

ALWAYS diff

git != svn | tfs | vss

git commit

git commit -a

git commit -a -m

git commit -a -m “[commit message]”

commit early, commit often

branches

branches• branching is EXTREMELY cheap in git

• performant

• easy (straight-forward)

• you will branch A LOT

• most branches will be local only

• branch life expectancy is very short

branches

git branch shiny-new-feature

git checkout shiny-new-feature

git checkout• switches active branch

• doesn’t actually ‘pull’ any files

• unless you “git fetch”

creating a branch

removing a branch

git merge

git merge <name-of-branch>

git mergetool• resolve merge conflicts using GUI of your choice
