Hi monks, there is a problem while sorting files as per specific fields running on different platforms.......for lunix i can specify the command 
       system ("sort -n -t , -k 1,3 input_file.txt > ss.txt");
       rename (ss.txt,  input_file.txt);

where the options and their meaning is as given 
       -k, --key=POS1[,POS2]
         start a key at POS1, end it at POS 2 (origin 1)


-t, --field-separator=SEP use SEP instead of non- to whitespace transi
+tion

 -n, --numeric-sort
              compare according to string numerical value

All this is done because i need the entire file to be sorted based on the 1st field only. The various fields are seperated by a space and a comma ( ,)... Is there any perl equivalent of the above code

Edited by Chady -- code tags addition to preserve formatting
