Hi ,

I would instead use a simple script like the one below to achieve same.

Hope this helps.




#! /bin/ksh

export SRC_DIR=/YOUR/SOURCE/DIRECTORY
export TGT_DIR=/YOUR/TARGET/DIRECTORY

for i in `ls $SRC_DIR`
do
echo $i

if [ -f $TGT_DIR/$i ]
then
echo " File exists - will not overwrite it !!!"
else
echo " File $i is not present on target directory - copying same"
cp $SRC_DIR/$i $TGT_DIR/$i
fi
done

mv

MV(1)								   User Commands							     MV(1)

NAME

       mv - move (rename) files

SYNOPSIS

       mv [OPTION]... [-T] SOURCE DEST
       mv [OPTION]... SOURCE... DIRECTORY
       mv [OPTION]... -t DIRECTORY SOURCE...

DESCRIPTION

       Rename SOURCE to DEST, or move SOURCE(s) to DIRECTORY.

       Mandatory arguments to long options are mandatory for short options too.

       --backup[=CONTROL]
	      make a backup of each existing destination file

       -b     like --backup but does not accept an argument

       -f, --force
	      do not prompt before overwriting

       -i, --interactive
	      prompt before overwrite

       -n, --no-clobber
	      do not overwrite an existing file

       If you specify more than one of -i, -f, -n, only the final one takes effect.

       --strip-trailing-slashes
	      remove any trailing slashes from each SOURCE argument

       -S, --suffix=SUFFIX
	      override the usual backup suffix

       -t, --target-directory=DIRECTORY
	      move all SOURCE arguments into DIRECTORY

       -T, --no-target-directory
	      treat DEST as a normal file

       -u, --update
	      move only when the SOURCE file is newer than the destination file or when the destination file is missing

       -v, --verbose
	      explain what is being done

       --help display this help and exit

       --version
	      output version information and exit

       The  backup  suffix  is `~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX.  The version control method may be selected via the --backup
       option or through the VERSION_CONTROL environment variable.  Here are the values:

       none, off
	      never make backups (even if --backup is given)

       numbered, t
	      make numbered backups

       existing, nil
	      numbered if numbered backups exist, simple otherwise

       simple, never
	      always make simple backups
