Change multiple filename formats with WHILE

Hi All,

I'm trying to run a simple shell program to change all the files named *.cvs to *.txt. I am trying to use WHILE and this is what I have so far:
Quote:
$ while [ $filename ]
> do
> mv $filename `basename $filename .cvs`.txt
> done
This changes the first file from *.cvs to *.txt, but it is not cycling through the other files.

My suspicion is that I don't have the right WHILE [CONDITION], but since I haven't used WHILE before I'm not sure how to do something like while [ $filename!=*.txt ] (psuedo code). Also, I am by no means tied to the WHILE command, if someone knows another command to do this I'd like to know.

Cheers,
ScKaSx

touch - Sets access and modification time of file

SYNOPSIS
bool touch (string $filename, [int $time = time()], [int $atime]) DESCRIPTION
Attempts to set the access and modification times of the file named in the $filename parameter to the value given in $time. Note that the access time is always modified, regardless of the number of parameters. If the file does not exist, it will be created. PARAMETERS
o $filename - The name of the file being touched. o $time - The touch time. If $time is not supplied, the current system time is used. o $atime - If present, the access time of the given filename is set to the value of $atime. Otherwise, it is set to the value passed to the $time parameter. If neither are present, the current system time is used. RETURN VALUES
Returns TRUE on success or FALSE on failure. CHANGELOG
