An easy yaourt install script for Arch Linux (and variants). Made so I can set up Arch either offline or online without having to remember what I need.

install-yaourt.sh

#!/bin/bash -e

make_a_pkg() {
    printf '** Making package "%s"...\n' "$1"

    tar zxf "$1.tar.gz"
    cd "$1"
    makepkg -si
    cd ..
}

download_dependencies() {
    echo '** Getting needed packages...'

    echo 'package-query'
    curl -O# https://aur.archlinux.org/packages/pa/package-query/package-query.tar.gz

    echo 'yaourt'
    curl -O# https://aur.archlinux.org/packages/ya/yaourt/yaourt.tar.gz
}

install_from_local() {
    make_a_pkg package-query
    make_a_pkg yaourt
}

install_as_repo() {
    echo '
[archlinuxfr]
SigLevel = Never
Server = http://repo.archlinux.fr/$arch
' >> /etc/pacman.conf

    pacman -Sy yaourt
}

show_help() {
    echo 'install-yaourt.sh  -  easy yaourt install script
Usage: install-yaourt.sh OPTION

Where option is one of:
  -r, --repo          Installs as repo. This is the recommended method if you
                        have an Internet connection
  -d, --get-depends   Downloads dependencies only (no installation). Could be
                        used for offline installation.
  -l, --local         Installs (using makepkg) after you have the dependencies
                        (e.g. using --get-depends or after manual download)
  --install-local     Basically calls --get-depends then --local.  It is
                        recommended to use --repo unless you have a reason not to'
}

if [[ "$1" == "--get-depends" || "$1" == "-d" ]]; then
    download_dependencies
elif [[ "$1" == "--local" || "$1" == "-l" ]]; then
    install_from_local
elif [[ "$1" == "--repo" || "$1" == "-r" ]]; then
    install_as_repo
elif [[ "$1" == "--install-local" ]]; then
    download_dependencies && install_from_local
else
    show_help
    exit 1
