Basic Commands

git config --global user.email [email protected]

initialize a git repository

git init

create a file called foo

git add foo

change foo

git commit foo

git diff

see the changes made

Create New Branch for separating your work

git brach NEW_BRANCH

git checkout NEW_BRANCH

do your stuff here

ex: add a file called "bar"

git checkout master

git merge NEW_BRANCH

if only addition done. Merge is done by fast-forwarding.

if a file is changed. merge done by recursive strategy

git push

send the changes to a remote repository

git fetch

Do a git fetch at any time to update your remote-tracking branches

git pull

A git pull is what you would do to bring a local branch up-to-date with its remote version, while also updating your other remote-tracking branches.

git stash

Use git stash when you want to record the current state of the working directory and the index, but want to go back to a clean working directory. The command saves your local modifications away and reverts the working directory to match the HEAD commit.
