        Bill.....I have bad news and good news.....

The script above  puts the new extension on every file
in the directory, regardless of its present extension...
The  test part is needed....

I am  a good way through your scripting tutorial,  and it
is the best one  out of a half-dozen I have on my box..

You take the time to explain what is going on, to answer
obvious questions that pop up,  and are oriented towards
functionality.  For example:  Not one of the other tutorials
mentions that you  bash has a help command.....

I've read the entire bash reference manual, and had no
idea that such a thing existed.......Nor do any of them
tell you that you put a function in your  .bashrc.....!  
(why don't you need to chmod +rx  it ? )  or enter them
on the cli.....

You have the makings of a really good book there...
(e or otherwise )

Thanks,

Bruce<+>
