Problem while traversing directories

I was given to create a backup of all files in a given directory(command line argument) into say /home/vishal/back and the back up files must be accordingly to the extension of the file i.e pdf files are saved in back/pdf doc files back/doc etc . I gave a recursive function to traverse through the given directory but im getting correct answers until this case exists

say the user gave user/yyy and lets say directroy yyy contains 2 directories xxx and zzz and one file say op.doc. If say xxx has 2 other directories and also some file,(there is no error when there is only directories and no file ). Here is my code ... please help

recur() <<<<recursive function>>>>>
{
echo $1
cd $1
for i in *
do
if [ -d $i ]
then recur $1/$i

else
filename=$i
extension=$(echo ${filename}|awk -F\. '{print $2}')
cd /home/vishal/back
count=0
for p in *
do
typ=$(echo ${p})
if [ $extension = $typ ]
then count=1
break
fi
done

if [ $count -eq 1 ]
then cp $1/$filename /home/vishal/back/$typ/
else
mkdir /home/vishal/back/$extension/
cp $1/$filename /home/vishal/back/$extension/
fi

fi

done
cd $1
cd ..
}

recur $1 <<<<$1 is user given directory>>>>>>>

ntdbbackup

NTDBBACKUP(8)						    System Administration tools 					     NTDBBACKUP(8)

NAME

       ntdbbackup - tool for backing up and for validating the integrity of samba .ntdb files

SYNOPSIS

       ntdbbackup [-s suffix] [-v] [-h]

DESCRIPTION

       This tool is part of the samba(1) suite.

       ntdbbackup is a tool that may be used to backup samba .ntdb files. This tool may also be used to verify the integrity of the .ntdb files
       prior to samba startup or during normal operation. If it finds file damage and it finds a prior backup the backup file will be restored.

OPTIONS

       -h
	   Get help information.

       -s suffix
	   The -s option allows the administrator to specify a file backup extension. This way it is possible to keep a history of ntdb backup
	   files by using a new suffix for each backup.

       -v
	   The -v will check the database for damages (corrupt data) which if detected causes the backup to be restored.

COMMANDS

       GENERAL INFORMATION

       The ntdbbackup utility can safely be run at any time. It was designed so that it can be used at any time to validate the integrity of ntdb
       files, even during Samba operation. Typical usage for the command will be:

       ntdbbackup [-s suffix] *.ntdb

       Before restarting samba the following command may be run to validate .ntdb files:

       ntdbbackup -v [-s suffix] *.ntdb

       Note that Samba 4 can use .tdb files instead, so you should use tdbbackup on those files.

       Samba .tdb and .ntdb files are stored in various locations, be sure to run backup all .(n)tdb files on the system. Important files
       includes:

       o   secrets.(n)tdb - usual location is in the /usr/local/samba/private directory, or on some systems in /etc/samba.

       o   passdb.(n)tdb - usual location is in the /usr/local/samba/private directory, or on some systems in /etc/samba.

       o   *.tdb and *.ntdb located in the /usr/local/samba/var directory or on some systems in the /var/cache or /var/lib/samba directories.

VERSION

       This man page is correct for version 4 of the Samba suite.

AUTHOR

       The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.

       The ntdbbackup man page was written by Rusty Russell, based on the tdbbackup man page by John H Terpstra.
