scripting

Hello,
 
I want to automate the download of the logfiles from our web server. The logfiles have names like ex+Date+.log. Is it possible to pass the filename generated by a shellscript to a lftp script?
 
for example my shell script gives me back ex090107.log and I need to pass this to the script to download the file and delete it after the download.
 
Thank you
 
Oliver
