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.

mvdir

mvdir(1M)																 mvdir(1M)

NAME

       mvdir - move a directory

SYNOPSIS

       dir newdir

DESCRIPTION

       moves one directory tree into another existing directory (within the same file system), or renames a directory without moving it.

       dir must be an existing directory.

       If newdir does not exist but the directory that would contain it does, dir is moved and/or renamed to newdir.  Otherwise, newdir must be an
       existing directory not already containing an entry with the same name as the last pathname component of dir.  In this case,  dir  is  moved
       and becomes a subdirectory of newdir.  The last pathname component of dir is used as the name for the moved directory.

       refuses	to  move  dir  if  the	path specified by newdir would be a descendent directory of the path specified by dir.	Such cases are not
       allowed because cyclic sub-trees would be created as in the case, for example, of which is prohibited.

       does not allow directory to be moved.
