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

sed 10q file
