automated file transfer?

[mike]

hi all,

i'm a unix newbie and i'm trying to do the following...

i'm TARing up a directory, then i need to transfer this file to
another machine.  so far i have a script to tar up the directory set
up using crontab to run every day at a certain time.  however, i need
to transfer this file to another machine and i was wondering if i can
do it in ftp all in one line?  in other words, how would i automate
logging into another machine via ftp, and transferring a file to that
remote machine?

thx
