Write a bash shell script, deleteFilesWithZeroLength.sh, that removes all zero length ordinary files in the directory passed as an optional argument. If you do not specify the directory argument, the script uses the present working directory as the default argument. Do appropriate exception handling in your script such as: a. If the arguments are more than 1, print out Too many arguments passed. b. If the argument passed is a regular file, print out XXX is regular file. c. If the directory doesnt exist, print out Directory XXX doesnt exist. Be sure to do the appropriate tests on your script without passing any arguments and when a directory is passed as an argument. Once successfully, the script should display Successfully deleted all zero length ordinary files in XXXX.
