Monks, I am in need of your wisdom. I have 2 files, that look something like this: File 1 
aa-aa1-aa
aa-aa2-aa
aa-aa2-ab
aa-aa3-bc

[download]
File 2 
V1111:something
V1111:something
V2222:something
V1111:something

[download]
A third file will look like this: 
aa-aa1-aa
aa-aa2-ab

[download]
I need to search file 1 for matches to file 3, and then output the corresponding line from file 2. So with the example above, the output should show 
V1111:something
V2222:something

[download]
Essentially, if the first match in file 1 is on line 3, I need line 3 from file 2. I have no idea on how to match those values up to get the output I need. Thanks as always for any ideas.
