sed - need to replace only the chars or symbol after 1st and 2nd dot(.) with "int1" and "int2" respectively.
Here is what I have tried but it replaces the strings in other lines.
End result should look like - A.int1.int2.any.string.here
sed -e 's//int1/' -e 's//int2/' -e 's/ABCD/int1/' filename
A...ABCD.DEFG.HIJK
A..ABCD.EFGH.IJKL
A.ABCD.EFGH.JKLM
