/usr/bin/tail

Print the last 10 lines of each FILE to standard output.

With no FILE, or when FILE is -, read standard input.

Mandatory arguments to long options are mandatory for short options too.

Usage: tail [OPTION]... [FILE]...

Arguments:
  [files]...

Options:
  -c, --bytes <bytes>            Number of bytes to print
  -f, --follow[=<follow>]        Print the file as it grows [possible values: descriptor, name]
  -n, --lines <lines>            Number of lines to print
      --pid <PID>                With -f, terminate after process ID, PID dies
