How do you find command line arguments as integer in shell scripting? - Answers

In shell scripting, command line arguments can be accessed using the special variable $1, $2, etc., where $1 refers to the first argument, $2 to the second, and so on. To treat these arguments as integers, you can use arithmetic expansion with the (( )) syntax. For example, you can perform calculations like sum=$(( $1 + $2 )) to add the first two arguments. Ensure the arguments passed are valid integers to avoid errors during arithmetic operations.
