Git Series: Installing Git on Linux

See the 3:45 min video here

If you are using Fedora 21 Workstation like me jump to step 5 ;)  

 

1 Installation

If you’re on Fedora-based, you can use yum:
$ yum install git
If you’re on a Debian-based distribution like Ubuntu, try apt-get:
$ apt-get install git
Configuration
There are two ways:

Modifying files
/etc/.gitconfig        # System level
~/.gitconfig          # User level
Repository/.git/.gitconfig   # Repository level

Using commands
git config --system # System level
git config –global    # User level
git config            # Repository level

 

2 Minimal

git config --global user.name “Xavier Figueroa”
git config -- global user.email “example@devm.com”
git config --list
user.name=Xavier Figueroa
user.email=example@devm.com
git config user.name

.gitconfig is hidden, so in order to see the file you need to use ls –a
xavi ~ $ ls -a

To see the content you can use
xavi ~ $ cat .gitconfig
xavi ~ $ tail .gitconfig
xavi ~ $ vim .gitconfig

 

3 Set Default Text Editor

git config --global core.editor "vim -w"
or set the GIT_EDITOR, VISUAL, or EDITOR environment variables.

 

4 Auto-Completion

curl -OL https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.bash
curl -OL https://raw.githubusercontent.com/git/git/master/contrib/completion/git-prompt.sh

Rename file
mv ~/git-completion.bash ~/.git-completion.bash
mv ~/ git-prompt.sh ~/ .git-prompt.sh

Edit ~/.bashrc
if [ -f ~/.git-completion.bash ]; then
source ~/.git-completion.bash
fi
if [ -f ~/.git-prompt.sh ]; then
source ~/.git-prompt.sh
fi

 

5 Improve the bash

Add the following ~/.bashrc

if [ -f /usr/share/git-core/contrib/completion/git-prompt.sh ]; then
source /usr/share/git-core/contrib/completion/git-prompt.sh
fi
green="\[\033[0;32m\]"
cyan="\[\033[1;36m\]"
purple="\[\033[1;35m\]"
reset="\[\033[0m\]"
export GIT_PS1_SHOWDIRTYSTATE=true
export GIT_PS1_SHOWUNTRACKEDFILES=true
export PS1="$purple\u$green\$(declare -F __git_ps1 &>/dev/null && __git_ps1 ' (%s)')$cyan \W $ $reset"


 

6 Getting help

git help to see the list of commands
git help <specific command> to see how to use the command
Pressing space or f will move you forwards or b pressing b will move you backwards as well
Pressing q stands for Quit will take you back to the command line
