Simple download manager using wget and shell script

I had to download a couple of large files from a web site. I built my own download manger which will download the file one after the other using simple wget tool and shell script. Thus the files were successfully downloaded over night without any human intervention !
The trick was simple,i had to just add the wget command with the url of the file to be downloaded one below the other in a shell script file.

for example
wget http://abc/a.jpg
wget http://def/d.jpg

scheduled downloads can be done by leveraging cron capabilities !
