This will give a good idea on how to do it
This is bad advice. That is a useless use of cat and a useless use of ls * and a useless use of backticks, not to mention a dangerous use of backticks! Also, a pointless use of temporary file. I often see two or three of these habits, but to see all five of them simultaneously is interesting. Remember that ls doesn't expand *, the shell does, so you can feed it straight into for.

A simpler and safer version is
Code:
for FILE in *filename*.doc
do
        echo mv "$FILE" some-destination-string
done

Remove the echo once you've gotten some-destination-string as exactly what you want it to be.

Rudic, yours is better, but there's no point using a pipe there -- too many arguments for for would also be too many arguments for ls, it doesn't help you.

vfs_crossrename

VFS_CROSSRENAME(8)					    System Administration tools 					VFS_CROSSRENAME(8)

NAME

       vfs_crossrename - server side rename files across filesystem boundaries

SYNOPSIS

       vfs objects = crossrename

DESCRIPTION

       This VFS module is part of the samba(7) suite.

       The vfs_crossrename VFS module allows server side rename operations even if source and target are on different physical devices. A "move"
       in Explorer is usually a rename operation if it is inside of a single share or device. Usually such a rename operation returns
       NT_STATUS_NOT_SAME_DEVICE and the client has to move the file by manual copy and delete operations. If the rename by copy is done by the
       server this can be much more efficient. vfs_crossrename tries to do this server-side cross-device rename operation.

       There are however limitations that this module currently does not solve:

	   The ACLs of files are not preserved,

	   meta data in EAs are not preserved,

	   renames of whole subdirectories cannot be done recursively, in that case we still return STATUS_NOT_SAME_DEVICE and let the client
	   decide what to do,

	   rename operations of huge files can cause hangs on the client because clients expect a rename operation to return fast.

       This module is stackable.

OPTIONS

       crossrename:sizelimit = BYTES
	   server-side cross-device-renames are only done for files if the filesize is not larger than the defined size in MiB to prevent
	   timeouts. The default sizelimit is 20 (MiB)

EXAMPLES

       To add server-side cross-device renames inside of a share for all files sized up to 50MB:

		   [testshare]
		path = /data/mounts
		vfs objects = crossrename
		crossrename:sizelimit = 50

VERSION

       This man page is correct for version 4.0.0 of the Samba suite.

       Source project similar to the way the Linux kernel is developed.
