one way is a quick shell script, as in

for index in `ls dir/*.asc`

mv dir/$index dir/${index}.sent

NTE- this may or may not work in your shell, depending
upon what shell you use, but pretty much all shells
can do somethig similar.

This can be made to work by simply putting
#!/bin/bash
as the first line and making the script executable.

That will break if there are spaces or other special characters in
any of the file names.

You don't need ls (it causes the problem):

for index in dir/*.asc

do
mv dir/$index dir/${index}.sent

This will try to move dir/dir/; dir/ is already included in
$index.

This will also break under the same conditions as using ls. Quote
your variables:

mv "$index" "${index}.sent"

done

Written correctly, it will work in all Bourne-type shells (bash,
ash, dash, ksh, pdksh, etc.).
