Pull new changes from remote

1. git pull is a convenient shortcut for completing both git fetch and git merge in the same command

   If you run into a merge conflict you cannot resolve, or if you decide to quit the merge, you can use git merge --abort to take the branch back to where it was in before you pulled.

2. Force to overwrite local files:

   git fetch --all

   git reset --hard origin/master

   git pull origin master

Set Username

1. set Git username for every repository on your computer:

   git config --global user.name "YourUserName"

   Setting your Git username for a single repository:

   git config user.name "YourUserName"

   check username:

   git config user.name

2. set your email address for every repository on your computer

   git config --global user.email "[e-mail]"

   Setting your email address for a single repository:

   git config user.email "[e-mail]"

   check email address:

   git config user.email

Set Password

Turn on the credential helper so that Git will save your password in memory for some time. By default, Git will cache your password for 15 minutes.

1. Set git to use the credential memory cache:

   git config --global credential.helper cache

2. Set the cache to timeout after 1 hour (setting is in seconds):

   git config --global credential.helper 'cache --timeout=3600'

Delete Commits

Reset the head to the number of commits back by 2 for example:

git reset --hard HEAD~2

and force pushed using:

git push -f origin master
