Hi All

I need to read the contents of the file (2 GB file size) in unix box and then assign into a variable. That time it shows Out of memory error. How to handle this scenario

bash-2.00$ uname
HP-UX
bash-2.00$ ulimit -a
core file size (blocks)     2097151
data seg size (kbytes)      1048576
file size (blocks)          unlimited
max memory size (kbytes)    unlimited
open files                  2048
pipe size (512 bytes)       16
stack size (kbytes)         256000
cpu time (seconds)          unlimited
max user processes          5001
virtual memory (kbytes)     unlimited

And my code is

my $contents;
open(my $fh, '<', 'control_report_file') or die "cannot open file cont
+rol_report_file $!";
{
   local $/;
   $contents = <$fh>;
}
close($fh);
