Print new item in file with symbol
Dear all,

I have encountered some problem here. I prompt the user for input and store it into a data file, eg. key in name and marks so the data file will look like this
andrew 80
ben 75

and the next input is carine 90. So the problem here is i want to print out carine with an asterik which will look like this.

*carine 90
andrew 80
ben 75

and the next new input is david 50 then it will look like this

carine 90
andrew 80
ben 75
*david 50
is there anyway i could achieve this?

I am doing this

Code:
print "\nPlease enter your name and marks :";

open (OUTFILE, ">>report");

$name = <STDIN>;
$mark = <STDIN>;
chomp ($name);
chomp ($mark);
print OUTFILE 
$abc = ("^$name\t$mark\n");
chomp ($abc);

close (OUTFILE);

and the printing out file is like this 

open (abc, "report") || die "Error opening data file: $!";

while (<abc>) { 
    push @array, [ split ];
foreach $list1 (@array) {
    foreach $list2 (@{$list1}) {
    print "'*'$list2\t";
}
print "\n";
}

Somehow this print out every element with *
Sorry for the messy code. And thank you in advance for any advice.

dmenu

DMENU(1)						      General Commands Manual							  DMENU(1)

NAME

       dmenu - dynamic menu

SYNOPSIS

       dmenu [-b] [-i] [-l lines] [-m monitor] [-p prompt] [-fn font] [-nb color] [-nf color] [-sb color] [-sf color] [-v]

       dmenu_run ...

       dmenu_path

DESCRIPTION

       dmenu is a dynamic menu for X, originally designed for dwm(1).  It manages huge numbers of user-defined menu items efficiently.

       dmenu reads a list of newline-separated items from standard input and creates a menu.  When the user selects an item or enters any text and
       presses Return, their choice is printed to standard output and dmenu terminates.

       dmenu_run is a dmenu script used by dwm which lists programs in the user's PATH and executes the selected item.

       dmenu_path is a program used by dmenu_run to find and cache a list of executables.

OPTIONS

       -b     dmenu appears at the bottom of the screen.

       -i     dmenu matches menu items case insensitively.

       -l lines
	      dmenu lists items vertically, with the given number of lines.

       -m monitor
	      dmenu appears on the given Xinerama screen.

       -p prompt
	      defines the prompt to be displayed to the left of the input field.

       -fn font
	      defines the font or font set used.

       -nb color
	      defines the normal background color.  #RGB, #RRGGBB, and color names are supported.

       -nf color
	      defines the normal foreground color.

       -sb color
	      defines the selected background color.

       -sf color
	      defines the selected foreground color.

       -v     prints version information to standard output, then exits.

USAGE

       dmenu is completely controlled by the keyboard.	Besides standard Unix line editing and item  selection	(Up/Down/Left/Right,  PageUp/Page-
       Down, Home/End), the following keys are recognized:

       Tab (Control-i)
	      Copy the selected item to the input field.

       Return (Control-j)
	      Confirm selection.  Prints the selected item to standard output and exits, returning success.

       Shift-Return (Control-Shift-j)
	      Confirm input.  Prints the input text to standard output and exits, returning success.

       Escape (Control-c)
	      Exit without selecting an item, returning failure.

       Control-y
	      Paste the current X selection into the input field.
