Hey Thanks all!
I got it ;)
open (FH, "+< $fname")|| die "\nFailed to open file $fname\n";
my $tmp=$fsize-$trunccount;

Here i paste a perl script to delete last Two Lines. If you want
delete more lines in a file you can specify it.
use File::ReadBackwards;
my $filename = 'test.txt';
my $Lines_to_truncate = 2; # Here the line to truncate is mean Remove
only Last Two Lines
my $bw = File::ReadBackwards->new( $fil

Hi All,
I need to truncate last few bytes of file. these files are big in size.
One idea is to write needed bytes to another file and delete the original

dont want to use truncate, it just truncating the size, all data is gone
any pointers
Thanks
