One common task when working with variables in Bash is to divide two variables, which might look simple. However, when working on Bash, you must need to do it with care.

This article is a detailed guide to divide two variables in Bash with some examples of how to use this operation in your scripts.

## How to Divide Two Variables in Bash

You can divide two variables in Bash using:

## Method 1: Divide Two Variables in Bash Using the expr Command

The **expr **command in bash evaluates an expression and prints the result to the console. To divide two variables using the** expr** command, here is an example code:

# Declare variables

num1=8

num2=4

# Divide variables using expr command

result=$(expr $num1 / $num2)

echo "Result: $result"

In this example, we are using the **expr** command to divide the value of num1 by the value of num2, the result of the division is stored in the result variable, which is then printed to the console:

## Method 2: Divide Two Variables in Bash Using the Double Parentheses

The **double parentheses** syntax is a shorthand way of performing arithmetic operations in Bash so to divide two variables using the double parentheses, here is an example code:

# Declare variables

num1=8

num2=4

# Divide variables using double parentheses syntax

result=$((num1 / num2))

echo "Result: $result"

Here, we are using the double parentheses syntax to divide the value of num1 by the value of num2, the result of the division is stored in the result variable, which is then printed to the console.

## Conclusion

Dividing two variables in Bash is a common task when working with numerical data. This article discussed two common methods for dividing two variables in Bash. By using the **expr** command and the double parentheses syntax, you can quickly and easily divide two variables in Bash scripts.
