SYNOPSIS
       tail [OPTION]... [FILE]...

DESCRIPTION
       Print  the  last  10  lines of each FILE to standard output.  With more
       than one FILE, precede each with a header giving the file  name.   With
       no FILE, or when FILE is -, read standard input.

       Mandatory  arguments  to  long  options are mandatory for short options
       too.

       -c, --bytes=N
              output the last N bytes; alternatively, use +N to  output  bytes
              starting with the Nth of each file

       -f, --follow[={name|descriptor}]
              output appended data as the file grows; -f, --follow, and --fol-
              low=descriptor are equivalent

       -F     same as --follow=name --retry

       -n, --lines=N
              output the last N lines, instead of the last 10; or  use  +N  to
              output lines starting with the Nth

       --max-unchanged-stats=N
              with  --follow=name,  reopen  a  FILE which has not changed size
              after N (default 5) iterations to see if it has been unlinked or
              renamed (this is the usual case of rotated log files)

       --pid=PID
              with -f, terminate after process ID, PID dies

       -q, --quiet, --silent
              never output headers giving file names

       --retry
              keep trying to open a file even when it is or becomes inaccessi-
              ble; useful when following by name, i.e., with --follow=name

       -s, --sleep-interval=S
              with -f, sleep for approximately S seconds (default 1.0) between
              iterations

       -v, --verbose
              always output headers giving file names

       --help display this help and exit

       --version
              output version information and exit

       If  the  first  character of N (the number of bytes or lines) is a `+',
