tail

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.
