perl program
I wish to write a Perl program that will provide a listing of files in a directory. The files must be listed in sorted order by the file name.
• By default, the program displays only file names.
• By default, the program lists the files in the current directory.
• The program must provide the following command line options to the user:
1)-d [directory]: This option allows the user to specify a directory or no directory name. If the -d option is provided without specifying a directory name, list your current directory. The output shall be displayed using the following column headers:
File Name Size Owner Group
2) -l: This option instructs the program to display a long listing. The output shall display the following column headers:
File Name Size Owner Group
3) The user selects no options. List the file names under your current directory. The output shall display the following column header:
File Name
NOTE: All other options are invalid for usage.
what would be some good ways to go about doing this?
