#!/bin/bash                                                                                                                                                                                 

if [ $# -eq 1 ]; then
    ppa_name=`echo "$1" | awk -F ':' '{print $2}'`
    app_name=`echo "$ppa_name" | cut -d '/' -f2-`

    if [ -z "$ppa_name" ]; then
        echo "PPA name not found"
        echo "Utility to add PPA repositories in your debian machine"
        echo "$0 ppa:user/ppa-name"
    else
        echo "$ppa_name" " $app_name"
        echo "deb http://ppa.launchpad.net/$ppa_name/ubuntu xenial main" > /etc/apt/sources.list.d/$app_name.list
        apt-get update > /dev/null 2> /tmp/apt_add_key.txt    
        key=`cat /tmp/apt_add_key.txt | awk -F ":" '{print $6}'  | awk '{print $2}'`
        apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv $key
        rm -rf /tmp/apt_add_key.txt
    fi  
else
    echo "Utility to add PPA repositories in your debian machine"
    echo "$0 ppa:user/ppa-name"
fi

保存这个脚本到/usr/bin目录下，名称为add-apt-repository，然后执行下列命令即可:

sudo chmod +x /usr/bin/add-apt-repository 
sudo chown root:root /usr/bin/add-apt-repository

添加PPA源

sudo add-apt-repository ppa:ppa_name

删除PPA源

sudo rm /etc/apt/sources.list.d/app_name.list

删除key

sudo apt-key del key
