Explanation

In shell scripting, $# is a special variable that holds the count of positional parameters passed to the script. When a shell script is executed with arguments like './script.sh arg1 arg2 arg3', $# will contain the value 3, representing the total number of arguments supplied. This is useful for validating argument counts before processing.
