Write a bash script which: if run without parameters, prints an error message and exits takes 1 parameter, which must be a valid path (absolute or relative) if run with 1 parameter which cannot be interpreted as a path, prints an error msg and exits if run with more than 1 parameter, uses the first parameter and ignores the rest if the value of the first parameter does not exist, creates it if the value of the first parameter exists but is not a directory, print an error msg and exit if the value of the first parameter exists, copies the script itself to that directory
