Hi, I have many tab delimited MASTER files (with header) in which last 3 columns of each line contains the path of another tab delimited files (CHILD). I need to read the MASTER files line by line and get the child file. Compare a key column captured from Master file in child file get few columns and add it to master file at the end. number of COLUMNS in Master files are not known so how can we do it in perl. Any help on this is appreciated.
