I need to use the data to plot graphs, the value of the column names should not be repeated and the values corresponding to each column should be listed one below the other where as in my case i am reading multiple files one after the other which also capture the header from each text files in between the data.Also i want to read each file separately so that i can associated a timestamps with it and its respective data.Thanks for the help and sorry for the code formatting i am new to Perl monks:P
