How can I do this in Unix ?

Rob Johnson_3 — Mon, 16 Jan 2006 20:40:07 GMT

I have a file that contains several hundred hostnames:
host1.domain.com
host2.domain.com
host3.domain.com
I need to put all hosts on one line and serate the name with a colon to look like this:
host1.domain.com:host2.domain.com:host4.domain.com.
How can I read the hostnames from a file and seperate them with a colon?
