-#Update script to run for most common linux distros
+# Synopsis: This script automates the process of updating software packages across multiple Linux distributions.
+# It checks for the available package manager (dnf, yum, apt, pacman, or zypper) and executes the appropriate commands to update the system.
+# Users can optionally allow the script to automatically reboot the system after updates by passing the --autoreboot flag.
+#
+# Usage:
+# Update with automatic reboot --autoreboot
+#
+# Note: The script is designed to be flexible, catering both to interactive use cases and automated workflows.

+#!/bin/bash

+# Synopsis:
+# This script is designed to check for available package updates on Linux systems. It supports multiple package
+# managers, including apt-get (used by Debian-based distributions like Ubuntu), dnf (used by Fedora), and yum
+# (used by CentOS and RHEL). The script identifies which package manager is available on the system and uses it
+# to check for updates. If updates are available, it lists them and exits with code 1. If updates cannot be checked,
+# it exits with code 2. If there are no updates, it exits with code 0.
+
+# Exit Codes:
+# 0 - Success: No updates are available.
+# 1 - Error: Updates are available (this script treats the availability of updates as an actionable item, thus 'Error').
+# 2 - Warning: The script was unable to check for updates, possibly due to an unsupported package manager or other issue.
+
+# The script provides a straightforward way for administrators and scripts to check for software updates across a
+# variety of Linux distributions using Tactical RMM, simplifying maintenance tasks and ensuring systems can be kept up to date with
+# minimal manual intervention.
