You could create a batch file to automatically connect you via FTP and then you can CD, COPY, MOVE and DEL from there.
The only other way you would be able to use your FTP space at the command line as if it were a local drive on your PC would be via a VPN connection and I don't see that as a possibility for a shared hosting plan. If you had a dedicated server, you might be able to, but I doubt it and wouldn't recommend it.
Here's how you can create a batch file that automatically logs into your FTP:
File1 - In notepad, create a file named "ftpfile1.ftp" and enter the following information:
<your ftp username>
<your ftp password>
binary (<---this is an optional ftp command, but I found it necessary when downloading files from one of my other FTP sites)
File2 - In notepad, create a file named ftplaunch.bat and enter the following information:
ftp -s:ftpfile1.ftp ftp.yourdomain.com (you can use an IP address instead of a FQDN)
Save both files in the same directory. When you launch the batch file (file #2), it will automatically open a command prompt and log you into the FTP site you entered in file #2. Then you can just issue FTP commands to cd, copy, move and delete files. I think this is about as close as you're going to get to having command line access to your hosting
