ok is it so..
thank you so i think i can do one thing like open the file ~/.bash_history
and then read the file..
actually i am trying this alternative..
but there is some error..
when i give it like
open(DAT, "~/.bash_history")or die("Cannot open file");
$raw_data=<DAT>;
print $raw_data;
i am getting an error like cannot open file..
i am presently running the script under the root user..
