$*

$* is a special variable in shell scripting that expands to all the positional parameters (arguments) passed to a script or function. It represents all the arguments as a single string, with each argument separated by the first character of the IFS (Internal Field Separator) variable, which defaults to a space, tab, and newline. This allows you to easily access and iterate over all the arguments provided to your script.
