changing extensions for multiple files at once
I copied some files to another folder, and I want to change them from .doc extensions to .txt extensions. I tried using the cp and mv commands, but it didn't work. Is it possible to change file extensions with these commands, and if so how do I do it? I tried using the * wildcard (say cp *.doc *.txt) but all I got was an illegal operation (or was it operand?) and nothing happened. I'm Using NeoOffice if that helps.
While I'm here, I'm learning about the text editors in terminal, but I can't seem to figure out how to set my preferences so I can move the cursor around with the mac. I have an iMac with Leopard 10.5.6, and I'm learning the Unix OS with a book for Tiger (the commands are the same, but some of the graphical windows and the options are changed/moved around).

Hey all,
I'm running a BASH shell and I was wondering if anyone knows a code to rename all the files in a directory. All I need to do is change the first character in the file from uppercase to lowercase and some of the files are already lowercase so they don't need to change.

mysql_fix_extensions
MYSQL_FIX_EXTENSI(1) MySQL Database System MYSQL_FIX_EXTENSI(1)
NAME
mysql_fix_extensions - normalize table file name extensions
SYNOPSIS
mysql_fix_extensions data_dir
DESCRIPTION
mysql_fix_extensions converts the extensions for MyISAM (or ISAM) table files to their canonical forms. It looks for files with extensions
matching any lettercase variant of .frm, .myd, .myi, .isd, and .ism and renames them to have extensions of .frm, .MYD, .MYI, .ISD, and
.ISM, respectively. This can be useful after transferring the files from a system with case-insensitive file names (such as Windows) to a
system with case-sensitive file names.
Invoke mysql_fix_extensions like this, where data_dir is the path name to the MySQL data directory.
