Arranging files
Hi all,
This is program to identify and arrange programs(scripts) based on their she-bang values to a folder with the same name.
The parts of mkdir and copy and creating problems.I also doubt the use of hash...maybe some problems in it.
Please help out debugging this.

Code pasted at:
Paste Code

***Code also added by reborg:
Code:
1:  #!/usr/bin/perl -w
2:  use File::Find;
3:  use File::Copy;
4:  %ext=("perl",pl,"bash",sh,"sed","ed","awk","aw");
5:  find(\&call,".");
6:  sub call{
7:   $var=$File::Find::name ;
8:   open(fh,$var) or die "Couldn't open file"; 
9:   $line=<fh>;
10:  if($line=~/^\#!.*?(\w+)\s+/){$dir=$1;}
11:   $p= $ext{$dir};
12:  if($var=~/(\w+\.)\w+/)
13:  {$new=$1.$p;}
14:  else
15:  {$new=$var.".".$p;}
16:  mkdir $ext unless( -e $ext);
17:  $newfile=$dir."/".$new;
18:  rename($var,$new);
19:  copy("$new","$newfile") or die "$!";
20:  close(fh);
21: }


These are the errors

There are some parts that are incompletely done due the errors that are being faced now.
Unquoted string "pl" may clash with future reserved word at ./arrange line 4.
Unquoted string "sh" may clash with future reserved word at ./arrange line 4.
Unquoted string "fh" may clash with future reserved word at ./arrange line 8.
Unquoted string "fh" may clash with future reserved word at ./arrange line 19.
Use of uninitialized value in pattern match (m//) at ./arrange line 10.
Use of uninitialized value in hash element at ./arrange line 11.
Use of uninitialized value in concatenation (.) or string at ./arrange line 13.
Use of uninitialized value in -e at ./arrange line 16.
Use of uninitialized value in mkdir at ./arrange line 16.
Use of uninitialized value in concatenation (.) or string at ./arrange line 17.
Is a directory at ./arrange line 18.


Forgive me if these are due to silly mistakes,as I am just starting with perl.

update-metainit

UPDATE-METAINIT(1)					User Contributed Perl Documentation					UPDATE-METAINIT(1)

NAME

       update-metainit - Generates init scripts

SYNOPSIS

       update-metainit [--remove initname [--purge] ]

DESCRIPTION

       Metainit solves the problem of writing good init scripts. Instead of manually creating these important files, they are derived from a
       declaritive description in the metainit files in /etc/metainit. These files can be shipped with packages or created by the local adminis-
       trator.

       If update-metainit called without argument, it will regenerate init scripts for all the files in /etc/metainit. The generated files contain
       a large warning in form of a comment that they will be overridden. Modifications are preferably done in the files in /etc/metainit and made
       effective by running update-metainit. If needed, the administrator can prevent modified init files by removing the warning comment.

OPTIONS

       --remove initname
	   This command will remove any generated and non-modified scripts that were created by the metainit file with the name initname.

       --purge
	   Only usable with --remove. Will remove the generated files even if modified.
