Hi to all, I need to relese a script by today itself. please help me to do this. I have a big file lets say 65 thousand lines. it is a tab seperated text file. i need to add one more columne at the end of every line ( tab seperated). the value of that column is the first column of the first line. example: Inputfile: NY^hhhhh^hhhhh^kkkkk^gggg hhh^jjjjj^9999^44444 888^hhhh^443444^hhhhhh Output file NY^hhhhh^hhhhh^kkkkk^gggg^NY hhh^jjjjj^9999^44444^NY 888^hhhh^443444^hhhhhh^NY here '^' represent tab character.
