Ruby FTP Application

Ruby FTP Application

This is a simple FTP application written in Ruby v2.0.0 that allows a user to connect to an FTP server and remove, upload, and download files.

The program is run by specifying either the help arguments (-? or -h) or by specifying a username and hostname through the command line. If the user runs the program using the help argument, the following dialog is displayed:

Casey:~$ ruby ftp.rb -?
Usage: ruby ftp.rb [-?|-h|[user@host ]]
Parameters:
     -?                displays the usage information
     -h                displays the usage information
     user@host         attempts to make a connection to the specified host
                       using the username provided
     user@host <file>  connects to the specified host and uploads the 
                       file if it exists
Once connected the user has the following options:
     ls                   displays a list of the current directory's contents
     pwd                  displays the path to the current working directory
     cd [directory]       changes to the specified directory
     get [file]           downloads the specified file
     put [file]           uploads the specified file from the local system
     rm [file]            deletes the specified file in the current directory
     rename [file] [file] renames the first file to the name of the second file
     exit                 close the ftp connection and exit the application

This dialog gives the user the information that is needed to run the application.

Logging in and using the application

To log in and use the application, run the program specifying a username and hostname as the first argument:

Casey:~$ ruby ftp.rb [email protected]

You will then be prompted for a password. After authenticating, you then have the ability to use familiar commands such as ls, pwd, cd, rm, etc. See the help display above for more information.
