How to Configure Network Connection After Centos Minimal Install

   with the following value

Favorite Git Config

Having used to type git commands won’t make us able to remember those long line commands. I always relies on git alias. I would like to share with you my favorites git aliases.

You can either type the following command to add the alias into your git config.

git config --global alias.lol "log --pretty=format:'%C(green)%h %C(red)%ad %C(cyan)%an%C(green)%d %Creset%s' --date=short --graph"

git config --global alias.recent "for-each-ref --sort=-committerdate refs/heads --format='%(HEAD)%(color:yellow)%(refname:short)|%(color:bold green)%(committerdate:relative)|%(color:blue)%(subject)|%(color:magenta)%(authorname)%(color:reset)'"

git config --global alias.lg-tag "log --no-walk --tags --pretty='%h %d %s' --decorate=full"

git config --global alias.st status
git config --global alias.co checkout
git config --global alias.br branch
git config --global alias.ci commit

Or, you can also add new line to~/.gitconfig

Finally, to double check you can try the alias directly, or simply list them down.

$ git config --list | grep alias

alias.lg=!git lg1

alias.lg1=!git lg1-specific --all

alias.lg2=!git lg2-specific --all

alias.lg3=!git lg3-specific --all

alias.lg1-specific=log --graph --abbrev-commit --decorate --format=format:'%C(bold blue)%h%C(reset) - %C(bold green)(%ar)%C(reset) %C(white)%s%C(reset) %C(dim white)- %an%C(reset)%C(bold yellow)%d%C(reset)'
