yeo - AUR helper helper for Arch Linux

yay helper to intput sudo password at command entry

With this script, you can run sudo yeo -Syy some-package --noconfirm and sudo yeo -Syyu --noconfirm (et al) instead of needing to babysit for a sudo password in the middle of the usual yay -Syy some-package --noconfirm

Use at your own risk!

Disclaimer: Anything on this page could result in destroying your entire computer or bring the apocalypse or something less or between or far worse! Only use this tool if you know how to use pacman and yay and can install Arch Linux yourself and don't like SysAdmin wages for a CLI babysitting job!

Reasoning

• yay will prompt the SysAdmin or user for sudo passwords in the middle of its execution, meaning the SysAdmin must babysit the terminal during yay installs and updates
• This defeats the purpose of using the terminal and scripts, meaning SysAdmin-level hourly cost to watch yay work

However, the premise is correct...

• Compiling must not be done by root or sudo
• A root user compiler can cause many problems, including code not be executable by normal users
• But, yay both compiles and installs, and installing does require sudo

How yeo helps...

• yeo must be run as sudo, then runs yay as a user that does not need a password for sudo operations as they arise

Solution

• Run a sudo command that takes the sudo password for the duration of the CLI execution, but runs yay through a normal user which has a no-password sudo permission
• This normal (worker) user requires a sudo password or root permissions to be initiated, but then does not need a password later
• The result is that:
  1. The sudo password CLI request moves up to the beginning of the workflow
  2. Where the sudo password only needs to be entered once
  3. Thus, we have a "press and walk" sudo command more like pacman

Prerequesites:

1. sudo

Arch Linux does not come with sudo ready by default

If you have not already enabled sudo, you can enable sudo with this, otherwise skip to 2...

| Turn on sudo: # (must run as root)

groupadd sudo
sed -i "s?# %sudo\tALL=(ALL) ALL?%sudo\tALL=(ALL) ALL?" /etc/sudoers

2. yay

yay must be installed already, if it is then skip 2...

| Install yay AUR helper : $

sudo pacman -Syy --needed base-devel git
cd ~
git clone https://aur.archlinux.org/yay.git
cd yay
makepkg -si --noconfirm
cd ..
rm -rf yay

Install yeo

First check for dependencies and any conflict

| Check for yeo tool dependencies & conflicts: $

if which yay && id -u worker; then if which yeo; then echo "yeo may already be installed!"; else echo "Ready to install yeo!"; fi else echo "Cannot install yeo, there is a conflict!"; fi

If you see the message Ready to install yeo! then you are ready to proceed...

| yeo install: $

sudo groupadd worker
sudo useradd -g worker worker
sudo usermod -a -G wheel worker
sudo mkdir -p /opt/vrk/worker
sudo chown -R worker:worker /opt/vrk/worker
sudo usermod -d /opt/vrk/worker worker
sudo usermod -L worker
sudo chsh -s /usr/sbin/bash worker
sudo echo 'worker ALL=(ALL) NOPASSWD: ALL' > /etc/sudoers.d/worker
sudo cat <<'EOF' > /opt/yeo.sh
#!/bin/bash
if [ "$(id -u)" != "0" ]; then
  /usr/bin/echo "Must run as root or sudo!"
  exit 1
fi

/usr/bin/echo $@ | /usr/bin/grep -q '"'
if [ "$?" != "0" ]; then
  /usr/bin/echo $@ | /usr/bin/grep -q "'"
  if [ "$?" != "0" ]; then
    args="$@"
    /usr/bin/sudo -u worker /bin/bash -c "/usr/bin/yay $args"
    exit $?
  else
    /usr/bin/echo "No 'quotes' allowed!"
    exit 1
  fi
else
  /usr/bin/echo "No \"quotes\" allowed!"
  exit 1
fi
EOF
sudo chmod 755 /opt/yeo.sh
sudo ln -sfn /opt/yeo.sh /usr/local/bin/yeo

Now, you have the option to run sudo yeo where you would normally run yay, including with --noconfirm or such yay options if you like
