Adding to the front of a line

[Ray Parrish]

Hello,

I've downloaded a text file of the new sites to block to avoid the 
conficker worm that is currently infecting Windows users, and would like 
to send it to my Windows using friends and family. However the file 
unfortunately has only the host names, one per line. I would like to add 
the 127.0.0.1 and a space to the front of each line in the file before I 
send it out, so all they have to do is copy and paste it's contents to 
the end of their hosts files.

I know that this task is very easy with the Linux command line, but am 
not experienced enough yet with bash scripting and command line work to 
know how to do it. Could someone please steer me to the commands I need 
to read up on in order to accomplish this task?

Thanks, Ray Parrish
