Unix - FTP (script) help

I want to write a script to do the FTP for me, but Im not sure how to go about doing it.Can someone give me some help here.I assume it must be done in shell script.I guess the script will look something like this:ftp www.mma.tv:USER:PASSWORD (is that how to embed the id/pwd?)
cd MyDir (can you change directories with a script? How do you get it to recognize the -Enter- key?)
mput File.txt
mv File.txt* File.done (would this work if there are multiple names? File1.txt, File2.txt, etc)
mv *.done Archive (moves the files to an Archive dir)Thanks!
