Well i converted it to qw and made lots of modifications and ended up with 2 versions of working code(late at night).One using find and copy modules,other using directory handler.I

Quote:
#!/usr/bin/perl -w
use File::Find;
use File::Copy;
%ftypes=qw(perl pl bash sh sed ed awk aw sh sh); #Put extensions associated with each type in hash
find(\&call,"."); #Call subroutine when file found

sub call
{
$var=$File::Find::name ;
if(-f $var) #Read only files
{
open(fh,$var) or die "Couldn't open file";
$line=<fh>;
if($line=~/^\#!.*?(\w+)\s+/){$dir=$1;$ext=$ftypes{$dir};} #Identify type from she-bang and extract extension from hash
if($var=~/(\w+\.)\w*/){$new=$1.$ext;} #In case file already contains extension,extract filename
else{$new=$var.".".$ext;}
mkdir $dir unless( -e $dir); #Make directory by type name
$newfile="./".$dir."/".$new;
$newfile=substr($newfile,2);
rename "$var", "./"."$new"; #Add proper extension by renaming
copy("$new","$newfile") or die "$!"; #Copy to created directory
close(fh);
}
}
And

Quote:
#!/usr/bin/perl
%ftypes=qw(perl pl bash sh sed ed awk aw sh sh); #Put extensions associated with type in hash
opendir dirhndl,"." or die "Cannot open directory:$!";


while($file=readdir(dirhndl))
{
next if $file =~ /^\.\.?$/;
open fh,$file;
$line=<fh>;
if($line=~/^\#!.*?(\w+)\s+/){$dir=$1;$ext=$ftypes{$dir};}#Identify type from she-bang and extract it
if($file=~/(\w+\.)\w*/){$new=$1.$ext;} #In case file already contains extension,extract filename
else{$new=$file.".".$ext;}
mkdir $dir unless( -e $dir); #Make directory by type name
$newfile="./".$dir."/".$new;
$newfile=substr($newfile,2);
rename "$file", "$newfile"; #Add proper extension and move to folder
close(fh);
}
closedir(dirhndl);
If there are any suggestions or bugs,please do tell,it would really help as I am learning Perl.

whereis

whereis(1)						      General Commands Manual							whereis(1)

Name
       whereis - locate source, binary, and or manual for program

Syntax
       whereis [-sbm] [-u] [-SBM dir... -f] name...

Description
       The command locates source/binary and manuals sections for specified files.  The supplied names are first stripped of leading pathname com-
       ponents and any (single) trailing extension of the form ``.ext'', for example,``.c''.  Prefixes of ``s.'' resulting from use of source code
       control are also dealt with.  The command then attempts to locate the desired program in a list of standard places.

Options
       -S dir
	  Search for source files in specified directory.

       -B dir
	  Search for binary files in given directory.

       -M dir
	  Search for manual section files in given directory.

       -b Searches only for binary files.

       -f Terminates last directory list created from use of -S, -B or -M flags and signals the start of file names.

       -m Searches only for manual section files.

       -s Searches only for source files.

       -u Searches for files that do not have one of binary, source or manual section files.  A file is said to be unusual if it does not have one
	  entry of each requested type.  Thus ``whereis -m -u *'' asks for those files in the current directory which have no documentation.

Examples
       The following finds all the files in which are not documented in with source in
       cd /usr/ucb
       whereis -u -M /usr/man/man1 -S /usr/src/cmd -f *

Restrictions
       Since the program uses to run faster, pathnames given with the -M -S and -B must be full.  That is, they must begin with a ``/''.

Files
       /usr/src/*
       /usr/{doc,man}/*
       /lib, /etc, /usr/{lib,bin,ucb,old,new,local}
