Depends on the shell you are using. If you are using csh or tcsh, type
at the command prompt,
% foreach file ( *.txt )
foreach? mv $file ${file:r}.ltr
foreach? end
Where '%' and 'foreach?' will be the prompts you get. Easy to move
that to a script form. See 'man csh' or the shell of your choice.

Ummm... It sounds like you are trying to make a command to be a front
end for 'at' that takes the exact same inputs as 'at...' Why not use
'at' in the first place and skip the extra step?
