I'm not sure if your sleep is long enough?

Typically you use expect to script this.
Or for ftp, you put the user and password on the same line, and use -n.

Hi,

Try increasing your sleep time more. Especially the first sleep.
From sleep 1 to sleep 3 , etc. If it is a slow connection you will have to increase accordingly. Play with the sleep then might be ok if you do not want to use expect script.

Or Kermit, which has nice scripting features.
