MySQL How to swap parts of a file name?

I have a number of files that a structured like this:
Quote:
[*] descriptive_file_name.extension
Eg.
[1a34] file_name.ext1
[45xfb] another file name with spaces.ext2
[777] yatf with [text in brackets].ext3
[y4] also a file (plus).ext4

I would like to swap the [*] part with the descriptive_file_name part, so that it looks like this:
Quote:
descriptive_file_name [*].extension
Eg.
file_name [1a34].ext1

I know (or believe) that the two parts need to be assigned to variables that can then be swapped in a mv command, but I'm stuck on how to exactly perform this.

NAME
extlinux - install the SYSLINUX bootloader on a ext2/ext3 filesystem SYNOPSIS
extlinux [options] directory DESCRIPTION
EXTLINUX is a new syslinux derivative, which boots from a Linux ext2/ext3 filesystem. It works the same way as SYSLINUX, with a few slight modifications. It is intended to simplify first-time installation of Linux, and for creation of rescue and other special-purpose boot disks. The installer is designed to be run on a mounted directory. For example, if you have an ext2 or ext3 usb key mounted on /mnt, you can run the following command: extlinux --install /mnt OPTIONS
-H, --heads=# Force the number of heads. -i, --install Install over the current bootsector. -O, --clear-once Clear the boot-once command. -o, --once=command Execute a command once upon boot. -r, --raid Fall back to the next device on boot failure. --reset-adv Reset auxiliary data. -S, --sectors=# Force the number of sectors per track. -U, --update Updates a previous EXTLINUX installation. -z, --zip Force zipdrive geometry (-H 64 -S 32). BUGS
I would appreciate hearing of any problems you have with SYSLINUX. I would also like to hear from you if you have successfully used SYS- LINUX, especially if you are using it for a distribution. If you are reporting problems, please include all possible information about your system and your BIOS; the vast majority of all problems reported turn out to be BIOS or hardware bugs, and I need as much information as possible in order to diagnose the problems. There is a mailing list for discussion among SYSLINUX users and for announcements of new and test versions. To join, send a message to majordomo@linux.kernel.org with the line: SEE ALSO
