If the files don't need to use any particular set of letters:
Code
touch {a..b}{a..r}{a..y}.txt
If you need to go through the letters exhaustively, right-to-left:
Code
touch a{a..z}{a..z}.txt
touch b{a..h}{a..z}.txt
touch bi{a..p}.txt
Those are curly braces, by the way. They look like triangles on my screen.
