# gnf – Friendly wrapper around 'sudo dnf'
# Version 1.2
# Author: You
#
# Features:
#   • Implicit '-y' on install/remove/reinstall/downgrade (toggle with -n/--no-confirm)
#   • 'gnf update' pipeline:
#       - dnf update [-y] [--refresh]
#       - flatpak update (user + system)
#       - optional fwupd refresh+update
#     with its own flags: -r/--refresh, -f/--firmware, -n/--no-confirm, -y/--yes
#   • Passes any other 'dnf' subcommand straight to sudo dnf
#   • 'copr' sub-commands get auto '-y' for addrepo/removerepo/enable/disable/list

$PROGRAM – wrapper for sudo dnf with smart defaults

Usage:
  $PROGRAM [GLOBAL OPTIONS] COMMAND [COMMAND OPTIONS] [ARGS...]

GLOBAL OPTIONS (must precede COMMAND):
  -h, --help          Show this help and exit
      --version       Show version and exit
  -n, --no-confirm    Disable the automatic '-y' on supported commands
  -y, --yes           (Re-)enable the automatic '-y' (default)

COMMANDS:
  install, remove, reinstall, downgrade
     → Implicit '-y' unless disabled by global '-n'

  update   (alias: upgrade)
     → dnf update + flatpak update + optional fwupd
     → COMMAND OPTIONS:
          -r, --refresh     Pass --refresh to dnf update
          -f, --firmware    After dnf+flatpak, run fwupdmgr refresh && update
          -n, --no-confirm  Do NOT add '-y' to dnf update
          -y, --yes         Force '-y' on dnf update (default)
     → You may group short flags: e.g. -rf or -fr

  copr     (subcommands: addrepo, removerepo, enable, disable, list, …)
     → For addrepo/removerepo/enable/disable/list, we auto '-y'
     → Other copr actions are passed straight through

  any other dnf COMMAND is forwarded to 'sudo dnf'

EXAMPLES:
  gnf install vim git
  gnf -n install firefox         # interactive remove/install
  gnf update                     # dnf update -y ; flatpak
  gnf update -r                  # + --refresh
  gnf update -rf                 # + firmware
  gnf -n update --refresh        # no -y, + refresh
  gnf copr addrepo user/project
