# tail
``tail`` shows the last lines of a file.

By default it shows the last 10 lines. Specify with ``-n``.
Skip the first 8 lines with ``tail +8 file.txt``

With multiple files it prepends each with a header. Use this with ``tail -n 999 msg1 msg2``  to view each file with a header in one screen.

Use ``-c 16`` to output the last 16 bytes.

To 'watch' a file use ``-f`` and specify time interval in seconds with ``-s``. Or just use ``watch``
