To calculate a percentage in Linux, you can use the bc command-line utility or write a simple script. Here are two methods:

  1. Using bc command: Open the terminal. Type bc and press Enter to open the bc calculator. Enter the division expression, where the numerator is divided by the denominator. Multiply the result by 100 to get the value as a percentage. For example, to calculate 25% of 80, enter 25 / 80 * 100. Press Enter to get the result.
  2. Using a shell script: Open a text editor and create a new file, let's say Add the following code to the file: #!/bin/bash numerator=25 denominator=80 percentage=$((numerator * 100 / denominator)) echo "The percentage is: $percentage%" Modify the values of numerator and denominator variables as per your requirement. Save the file and exit the text editor. Open the terminal, navigate to the directory where the file is located, and run the script using the following command: chmod +x ./ The script will calculate the percentage and display the result in the terminal.

In both methods, you can substitute the numerator and denominator values with your own numbers to calculate different percentages.
