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
e2label - Change the label on an ext2/ext3/ext4 filesystem SYNOPSIS
e2label device [ volume-label ] DESCRIPTION
e2label will display or change the volume label on the ext2, ext3, or ext4 filesystem located on device. If the optional argument volume-label is not present, e2label will simply display the current volume label. If the optional argument volume-label is present, then e2label will set the volume label to be volume-label. Ext2 volume labels can be at most 16 characters long; if volume-label is longer than 16 characters, e2label will truncate it and print a warning message. It is also possible to set the volume label using the -L option of tune2fs(8). AUTHOR
e2label was written by Theodore Ts'o (tytso@mit.edu). AVAILABILITY
