################################################################################
# This script checks for the Linux operating system and uses the appropriate
# package manager to install the zsh shell, tmux, and byobu. To run this script
# directly from GitHub Gist, use the following command:
#
#   bash <(curl -s https://gist.githubusercontent.com/dnegi-dev/af4bd1abc162413b3236f4cd9c2de4f1/raw/4e9c8ecd3fc82fe97e9792850844b3ab588c53a0/install_zsh_and_byobu.sh)
#
# The script will automatically detect the package manager used by the system
# and install zsh, tmux, and byobu using that package manager. Supported package
# managers are:
# - apt-get (Ubuntu, Debian, and other Debian-based systems)
# - dnf (Fedora, Red Hat, CentOS)
# - yum (older Red Hat, CentOS)
# - zypper (OpenSUSE)
# - emerge (Gentoo)
# - pacman (Arch Linux)
