Basic problem

Hello Friends,

I am learning Perl now. I have a small query.

I have a directory Z with file name Z.txt.
I would like to copy this file Z.txt to 3 new dir with new filenames as follows
dir 1 1.txt
dir 2 2.txt
dir 3 3.txt

I would like to then open 1.txt from dir 1 and edit the first 4 lines and it
would be better if the program can ask me what to enter in these lines. I need to do the same for all the directories.

For eg: I have a line as follows.
x y Z
10 11 12

Th program should ask me what to enter for Y value. So when the program asks, Igive it a new value.

I have tried the following and I guess there is a much shorter way to do this

#!/usr/bin/perl
open FILE, "z.txt" or die $!;
while (<FILE>) {
print $_;
}
mkdir("1", 0777) || print $!;
copy("z.txt","1.txt") or die "Copy failed: $!";
move("1.txt","/home/privat/temp/PerlWD/1");
mkdir("2", 0777) || print $!;
copy("z.txt","2.txt") or die "Copy failed: $!";
move("2.txt","/home/privat/temp/PerlWD/2");
mkdir("3", 0777) || print $!;
copy("z.txt","3.txt") or die "Copy failed: $!";
move("3.txt","/home/privat/temp/PerlWD/3");
print " -Done";
exit;

I am not sure how to edit the file and then save it in the respective file name.

Looking forward to your response.

Regards,
Ramesh

       --analyze Run the dds analyzer on the boards and print the resulting numberof tricks (warning SLOW)

       --criteria=
		 A  list of criteria to apply to each generated hand to generate specific hand types.  The list should be space separated and each
		 item may be suffixed with a colon and a (fractional) probability value which can be used to weight the criteria.

		 E.g. --criteria="weaknt:0.8 strongnt:0.5"

		 Valid criteria are: unbalanced weaknt strongnt twont strongtwo weaktwo three twoclubs 4441  singlesuit  twosuits  partscore  game
		 slam game-invite slam-invite jumpshift jumpfit splinter bacon weird

       --probability=factor
		 Generate  hands matching the criteria with only the given probability. Factor is in the range 0 to 1. On each attempt to generate
		 a board it is rejected if it doesn't match the criteria with the given probability.  A factor of about  0.8  gives  roughly  half
		 matching boards
