Hi All, I am trying to automate partitioning and formatting on Linux. So using fdisk command. Now the problem is when am passing piped inputs to the fdisk it is working correctly as expected. I also wanted to pass arguments from command line to my perl script. But it just stops after entering the interactive command prompt of fdisk when I try to pass arguments from command line! Is there anyway I can get this to work ? Does fdisk allow all the command line arguments at once(since it has kind of sub menus)? or is there anyway that I can automate such process by passing args through command line ??

use strict;
use warnings;

# Variable Declarations and Initialization
#
my $char = '"';
my $cmd;
our $device = '';

#
# Main Script Body
#
#check if device name is supplied 
if($#ARGV == 0)
         {
         $device = $ARGV[0]; # store device name in variable 
         # concatenate device name with fdisk command
        <b> $cmd = 'fdisk -c'.' '.$device.' < fdisk.input';</b> ######
+#This works
         system $cmd;
         exit 0;
         }
else    {
         print "Format Error:Usage- partition.pl <device_name>\n";
         print "Example: partition.pl "; 
         print $char; print "/dev/sdf"; print "$char\n";
         exit -1;            # displayed as 255
         }

fdisk.input has these params:
n
p
1
1
+G
t
83
w

## this modification does not work :(

$cmd = 'fdisk -c'.' '.$device.' n p 1 1 +G t 83 w';
# this displays fdisk usage error

nor does this work

$cmd = 'fdisk -c'.' '.$device;
system $cmd;
system " n p 1 1 +G t 83 w";
## this however enters the fdisk prompt and waits for the above inputs
