I am trying to get the name of the user from one file and their corresponding details from my other file.

I use the command

awk -F : '{ print $1 }' user-name

it gives me the list of all the user's. So now how can I match these names with the other file and get a output like:

user-name id contact-details

The format of the two files is like follows:

1.user-name

Tarun:143
Rahul:148
Neeraj:149

2.user-details

Tarun:tarun@gmail.com
Neeraj:neeraj@xyz.com
Rahul:rahul@gmail.com

what I'm trying to get is like:

Neeraj:149:neeraj@xyz.com
Rahul:148:rahul@gmail.com
Tarun:143:tarun@gmail.com
