I used to know of a command -- an actual command mind you, not sed/awk magic -- that formatted its input to be aligned in columns. For example, if you ran:
% echo -e "aaaaa bbbbbbb\ncc ddd" aaaaa bbbbbbb cc ddd
But if you ran the output through the command which I've forgotten the name of:
% echo -e "aaaaa bbbbbbb\ncc ddd" | mystery_command aaaaa bbbbbbb cc ddd
Does anyone know the name of that command?
