OTS is now a full-fledged language that allows for scripts to be run through the terminal. One of the key features of any programming language is the ability to use variables. This document will guide you through the use of variables in OTS, including how to define, manipulate, and utilize them in your scripts.

You can define a new variable in OTS using the = symbol. The syntax is as follows:

varname = value

greeting = hello world

In this example, the variable greeting is assigned the value hello world.

You can redirect the output of any terminal command into a variable using the >> symbol. This is useful for capturing the output of commands and storing them in variables for later use.

ls >> home

This command sets/creates the variable home with the value of the output of the ls command, which lists the contents of the current directory.

You can call a variable in OTS using the $ symbol. This allows you to use the value stored in the variable in your commands or scripts.

ls >> home echo $home

In this example, the output of the ls command is stored in the home variable, and then echo $home prints the contents of the home variable, which would produce the same output as a normal ls command.

# Define a variable with a simple string message = Hello, OTS! # Print the message variable echo $message

Output:

Hello, OTS! 

# Capture the output of the 'pwd' command (prints the current directory) into a variable pwd >> current_dir # Print the current directory stored in the variable echo $current_dir

Output:

Origin/(C) Users/Username 

# List all files in the current directory and store in a variable ls >> files # Print the list of files stored in the variable echo $files

Output (example):

file1.txt file2.txt directory1 directory2 

# Define two variables first_name = John last_name = Doe # Combine variables to form a full name full_name = $first_name $last_name # Print the full name echo $full_name

Output:

John Doe 

Variables in OTS provide a powerful way to store and manipulate data, making your scripts more dynamic and flexible. By using the =, >>, and $ symbols, you can easily define, capture, and utilize variables in your terminal commands and scripts. Experiment with these features to enhance your OTS scripting capabilities!
