I need output like this:

I have tried

Try something like this to start with. If you find problems, show us what you did to fix them. First. Before saying 'this does not work':

find /abc -type d |
while read dir
   ls -1 /abc/$dir | awk -F '.' '{printf $(NF)' | sort -u |
   while read suffix
      printf "/abc/%s:*.%s"  $dir $suffix

Comment: this appears to be an attempt to do something else, and this is a problem you hit on the way to that something else's solution. It is an unusual request.
Is this homework?

find /abc -type f -printf "%h %f\n" | awk '
                EX = $2
                sub ( /[^.]*[.]/, X, EX )
                A[$1 FS EX]
        END {
                for ( k in A )
                        n = split ( k, T )
                        print T[1] "/:*." T[2]

Bash variable substitution option

Even this could do the trick:-

while read full_filename
   echo "${directory}${filenames}"
done < <(find /abc -type f) | sort -u

I'm not saying it's pretty; it is just another alternative if that suits your coding style. It uses very few processes, which might be important to performance if you have lots of files.

Assuming that this is to be used by something else that will expand it all again, is there a reason not to build this process into that code and remove the need to juggle it all and then re-expand?

Can you elaborate?

Thank you all.
find /abc | awk '{sub (/[^\/]*\./, "*."); T[$0]} END {for (t in T) print t}'

worked for me.

It is not homework Smilie
I have to prepare a list with all sub directories and with file extensions in all .
