Basic Installations

Arch Linux


    sudo pacman -Syu gcc make cmake python3 python-pip git wget nvim zsh cloudflared openssh rsync rclone
    sudo chsh -s $(which zsh) $(whoami)

# Then, ensure visudo has:
# %wheel ALL=(ALL:ALL) ALL

Debian / Ubuntu


# To add 'myuser' to the 'sudo' group
sudo usermod -aG sudo myuser

Fedora / RHEL / CentOS


# To add 'myuser' to the 'wheel' group
sudo usermod -aG wheel myuser

# Typically, wheel group is already configured in /etc/sudoers

oh-my-zsh installation

sh -c "$(wget https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh -O -)"

## Install plugins
git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting

plugins=(\
  git\
  zsh-syntax-highlighting\
  zsh-autosuggestions\
  zsh-history-substring-search\
)' ~/.zshrc

Generate SSH keys

ssh-keygen -t ed25519 -C "pc"
cat ~/.ssh/id_ed25519.pub

Add servers

mkdir -p ~/.ssh
echo "Host gila
        Hostname gila.navraj.me
        User gila
        Port 22
        ProxyCommand cloudflared access ssh --hostname %h
Host sol
        Hostname sol.asu.edu
        User sroy85
        Port 22
        ProxyJump gila" >> ~/.ssh/config

Add zshrc functions

mo() {
  # Check if an argument was provided
  if [ -z "$1" ]; then
    echo "Usage: mo <directory_name>"
    return 1 # Indicate an error
  fi

  # Attempt to create the directory.
  # -p: no error if existing, make parent directories as needed
  # --: ensures that $1 isn't misinterpreted as an option if it starts with '-'
  if mkdir -p -- "$1"; then
    # If mkdir was successful, try to cd into it
    if cd -- "$1"; then
      return 0 # Success
    else
      echo "Error: Successfully created directory '$1', but could not cd into it." >&2
      return 1 # Indicate an error
    fi
  else
    # mkdir failed. mkdir itself usually prints an error.
    # We can add a generic one too.
    echo "Error: Could not create directory '$1'." >&2
    return 1 # Indicate an error
  fi
}
