Shell script to find area of a circle?
To write a shell script to find the area of a circle, you can use the formula: area = π * radius^2. Here is an example shell script using the read command to input the radius from the user: #!/bin/bash echo "Enter the radius of the circle:" read radius area=$(echo "3.14159 * $radius * $radius" | bc) echo "The area of the circle with radius $radius is $area" This script first prompts the user to enter the radius, calculates the area using the formula, and then displays the result.

When might it be necessary or advisable to write a shell script instead of a shell function?
A shell function will do nothing unless it is explicitly called by other code, typically in a shell script. A shell script is a runnable, executable process, which can call other shell scripts and/or functions. The question might be worded backwards - it is necessary to write shell functions for shell scripts when certain logical functionality is required to be performed multiple times. Consider a shell function equivalent to a program subroutine - they operate the same way.
