NAME

       tail - deliver the last part of a file

SYNOPSIS

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

       tail [ -fr ] [ -n nlines ] [ -c nbytes ] [ 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 bytes, 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.

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 bytes  from
       0.

       Tail is ignorant of UTF.
