match field between 2 files
I would like to do the following in bash shell.

file a

a:1
b:2
c:3

file b

a:work:apple
b:baby:banana
c:candy:cat
d:desk:dog

I would like to match field 1 in file a to file b, if there's a match I would like
to append field 2 in file a to field 3 in file b.

Thank you.
