    BASIC GIT CONFIGURTION FOR BEGINNERS

To setup there are three levels of configuration

--local to set configuration for a single repo.
--global to set configuration for a your user.
--system to set configuration for all users.

Here i am using global in git configuration commmands, you can use any level of configuration as per your requirement.
Command to setup email:
$git config --global user.email example@domain.com

Command to setup username:
$git config --global user.name username

command to setup auto carriage return / line feed handling:
$git config --global core.autocrlf true

command to setup default file editor:
  $git config --global core.editor vim 

command to setup certificate path:
  $git config --global http.sslCAInfo cacert.crt

command to skip ssl certification.
  $git config --global http.sslVerify false

command to setup credential help.
  $git config --global credential.helper 'cache --timeout=300'

Command to setup username and token:
  $ git config --global github.user hemanth22

  $ git config --global github.token pastetokenhere

Command to setup default push configuration:
$git config --global push.default simple

or
$git config --global push.default matching

Difference between Simple and matching push.


simple
matching


Just Pushes current branch up to github.
Pushes all matching branches up to github.


Command to setup default pull configuration:
$git config --global pull.rebase true

By default git pull does git fetch + git merge
If you feel useless merge appearing then you enable rebase using above command,
or you can pull manually for any particular repo with rebase using below command line.
$git pull --rebase this will perform git fetch + git rebase
In simple difference.


git with default pull
git with rebase pull


$git pull
$git pull --rebase


$git fetch
$git merge
$git fetch
$git rebase


Command to setup resue recorded resolution:
$git config --global rerere.enabled true

Command to create aliases:
$git config --global alias.s "status -s"
$git config --global alias.lg "log --oneline --decorate --all --graph"
$git config --global alias.lg "log --color --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit"

Command to setup by pass for longpaths.
$git config --system core.longpaths true

Command to setup colour ui:
$git config --global color.ui true

command to list the setup:
