rename - change n'th character of regexp

Hi,

I wonder if its possible to do the following task using rename (perl v5.8.8).

I want to find filenames matching the specific pattern and then change chosen character of this pattern to a given character, e.g. do the following renaming:
regexp: 'a[12]b' -----> 'a0b'

What's the simplest solution for this? Is one-line rename possible?

Thx!

NAME
mrename - program to rename files SYNOPSIS
mrename 'pattern' prefix [option] DESCRIPTION
This manual page documents briefly the mrename command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page. mrename is a tool for easy and automatic renaming of many files. The 'pattern' is the pattern to search files to rename (quoted to avoid that bash resolve it), and prefix is the prefix that will be added to the name of each file. The two alternative options for copying or moving files in the new name are explained below. All parameters are needed, and you have to stay and launch the script in the same direc- tory of the files to be renamed. The program should be able to write in this directory. OPTIONS
There are only the following three options. -c The option -c will copy each file with the new filename. -m The option -m will move each file in the new filename. -h Display help. EXAMPLE
If you have a directory with two jpeg images prof.jpg and forp.jpg and you want to add them a prefix like item0, item1 etc.. (that is item0prof.jpg, item1forp.jpg etc..) do this: cd /path/to/the/images mrename '*.jpg' item -c to copy each matching file into another with the new name mrename '*.jpg' item -m to rename each file without keeping a copy with the previous name Word-Wide-Web: http://alfalinux.sourceforge.net/mrename.php3 AUTHOR
: Giancarlo -rofus- Erra e-mail: rofus@mindless.com This manual page was written by Dr. Guenter Bechly <gbechly@debian.org>, for the Debian GNU/Linux system (but may be used by others). It is distributed under the GPL just like mrename itself. October 22, 2000 MRENAME(1)
