Shell Programming and Scripting

I am facing a strange situation where I need to collect logs and consolidate them.

All logs are under say /tmp/useless and all logs are under subdir of the form IPaddresses_x_y
eg: /tmp/useless/105.52.34.246_3_1
/tmp/useless/105.52.1.118_0_10

There are several logs under each subdir and I want logs named interested.txt. I need to find them, consolidate them in 1 big log. easy enough. BUT there is no ID inside each log and so I need to insert the IP address from the subdir name at the top of each log before appending . I know I can get IP addresses by using cut, store them and use a loop. Not sure if this is the right approach. Any pointer is appreciated.

Code:

cd /tmp/useless
more */interested.txt > consolidated.log

wow! this is a simpel neat solution. Can I prevent the file name being printed ? I just need the dir name
