tail [ -fr ] [ -n nlines ] [ -c ncharacters ] [ file ]
Copying begins at position +number measured from the beginning, or -number from the end of the input. Number is counted in lines, 1K blocks or characters, according to the appended flag l, b, or c. Default is -10l (ten ell).
The further flag r causes tail to print lines from the end of the file in reverse order; f (follow) causes tail, after printing to the end, to keep watch and print further data as it appears.
The second syntax is that promulgated by POSIX, where the numbers of lines (-n) or characters (-c) are specified separately as signed integers. Note than an unsigned value is treated as negative, ie '-n 2' is equivalent to '-n -2'.
