BashUpdate is a simple Bash script for performing routine system updates and maintenance on Raspberry Pi and Debian-based systems. It not only updates system packages but also handles Docker maintenance and performs Raspberry Pi–specific tasks such as firmware updates and optional Unifi controller updates.

• System Updates & Upgrades:

  • Updates package lists using apt update
  • Performs a full system upgrade with apt full-upgrade
  • Removes unnecessary packages with apt autoremove

• Disk Space Check:

  • Verifies that a minimum disk space threshold (~512MB by default) is available before executing updates.

• Raspberry Pi Specific Tasks:

  • Checks for Raspberry Pi hardware and, if detected, prompts for a firmware upgrade using rpi-update
  • Optionally runs a Unifi update script (unifi-update.sh) if available

• Firmware Updates (fwupd):

  • Installs fwupd if not present
  • Lists available firmware devices with fwupdmgr get-devices
  • Refreshes firmware metadata with fwupdmgr refresh --force
  • Checks for firmware updates with fwupdmgr get-updates
  • Applies firmware updates with fwupdmgr update

• Docker Maintenance:

  • If Docker is installed, the script will run Docker-specific maintenance, including:
    • Downloading and executing dockcheck.sh if not present locally
    • Pruning unused Docker containers, networks, images, and volumes

• Verbose Mode:

  • Use the -v option to enable detailed output (using shell's debug mode).

• Operating System: Debian-based systems or Raspberry Pi OS
• Bash: Tested on version 4.x or higher
• Privileges: Must be run as root (or via sudo)
• Optional Dependencies:
  • rpi-update for firmware updates (the script will install it if missing)
  • fwupd for firmware updates (the script will install it if missing)
  • docker (if you want to perform Docker maintenance)
  • curl for downloading external scripts if needed
