RouterOS Scripting: An Introduction

Overview of RouterOS Scripting

• RouterOS features its own scripting language, allowing users to automate various tasks on their routers without needing advanced programming skills.

• The scripting process is similar to languages like Bash and Python, enabling direct command input in the terminal for testing and execution.

Creating and Storing Scripts

• Instead of traditional script files, scripts are stored in the system script section of RouterOS for better organization and permission management.

• Users can begin by naming their script, which opens a basic text editor with syntax highlighting for entering commands.

Variables and Data Types

• RouterOS supports 11 data types that are automatically recognized upon assignment; no prior declaration is needed.

• Variables can be declared as local or global. Local variables are created using a colon followed by "local" and the variable name.

Using Commands and Scope Management

• The put command displays variable values; local variables disappear after execution while global ones remain in RAM until cleared.

• It's recommended to use local variables due to their limited scope, avoiding unnecessary use of global variables.

Arithmetic Operations and Conditional Statements

• RouterOS scripting includes typical arithmetic operators but lacks a power operator; bitwise operations may occur if incorrect symbols are used.

• Conditional statements can be implemented using an if structure followed by actions enclosed in curly brackets.

Functions, Loops, and Automation Potential

• Functions are defined similarly to variables but include action commands. A simple loop can call these functions for repetitive tasks.

• The potential for automation is significant with built-in triggers like Scheduler, Netwatch, and DHCP actions available within RouterOS scripting.
