Alongside other bash alias commands and directly in the terminal as a command. To use bash functions, follow the outlines below. Bash Function Syntax There are two different ways to declare a bash function: 1. The most widely used format is: ...
$1represents the first argument passed to the function (in this case, the user’s name). When you run the script, you’ll see: Hello, Alice! Welcome to Bash scripting! Hello, Bob! Welcome to Bash scripting! You can pass different names to the function, making it reusable. Functions ar...

Next we calculate the factorial of 'num' using a loop and store the result in the 'result' variable.4.Maximum and Minimum Functions:Write a Bash script that defines functions called maximum and minimum which take two numbers as arguments and print the maximum and minimum of the two, respecti...
7. Using Functions for Argument Validation 8. Conclusion 1. Overview In Bash scripting, it’s often necessary to verify the number of arguments passed to a script to ensure correct script execution. This is crucial in scenarios where the script’s behavior depends on user-provided inputs. In...
Using functions in bash scripting comes with two benefits: 1. A function is read directly into the shell's memory and stored for later use. Since computer memory is not an issue nowadays, using functions is faster than repeating code. ...
