Without the -n option only the last 50 lines are displayed on the terminal window. With the -n option all the lines are displayed. Further, the number of lines reported by piping the output to wc -l from both forms of invocation gives the same line count notwithstanding they do not display the same number of lines. This does not happen when using a simple ssh session.
