The difference between the first two is the input to the "mail" command.
In the first case the input is the output of the "ls -l" command,
so a pipe is required.
In the second case, the input is already in a file, so redirection
of the "mail" command stdin works.
In the third case, you are piping the file to stdin of the "mail"
command. This is equivalent of the second case. I prefer the
second case to the third case, but I assume that the difference
in execution time is minimal.
