Sure, there are lots of ways of doing similar things. In the case of the
above, though, they are actually functionally different. In the former
case, your shell is invoking two programmes and establishing
communication between them. The first disadvantage of this is that it
uses two processes when only one is necessary (slightly inefficient).
Furthermore, 'less' will be unable to provide certain features such as
summarising your position within the document, seeking rapidly to the
end of the "file", supporting editing, etc.
