TAIL(1) 			     General Commands Manual				  TAIL(1)

NAME
       tail - deliver the last part of a file

SYNOPSIS
       tail [ +-number[lbc][rf] ] [ file ]

       tail [ -fr ] [ -n nlines ] [ -c ncharacters ] [ file ]

DESCRIPTION
       Tail  copies the named file to the standard output beginning at a designated place.  If no
       file is named, the standard input is copied.

       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 or Default is -10l (ten ell).

       The further flag causes tail to print lines from the end of the	file  in  reverse  order;
       (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 rather than the  options
       are signed.

EXAMPLES
       tail file
	      Print the last 10 lines of a file.

       tail +0f file
	      Print a file, and continue to watch data accumulate as it grows.

       sed 10q file
	      Print the first 10 lines of a file.

SOURCE
       /sys/src/cmd/tail.c

BUGS
       Tails  relative	to the end of the file are treasured up in a buffer, and thus are limited
       in length.
       According to custom, option +number counts lines from 1, and counts blocks and  characters
       from 0.
