TAIL(1)                 COMMAND REFERENCE                 TAIL(1)



NAME
     tail - copy the last part of a file to standard output

SYNOPSIS
     tail [ +[number][lbc][fr] ] [ filename ]

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

     Copying begins at distance +number from the beginning, or
     -number from the end of the input.

     Specifying r causes tail to print lines from the end-of-file
     in reverse order.  The default for r is to print the entire
     file this way.  Specifying f causes tail to not quit at
     end-of-file, but rather wait and try to read repeatedly in
     hopes that the file will grow.  If both r and f are given,
     the f is ignored.

OPTIONS
     -f Causes tail to not quit at end-of-file, but rather wait
        and try to read repeatedly in hopes that the file will
        grow.

     -r Causes tail to print lines from the end of the file in
        reverse order.

     +number
        Copying begins at distance +number from the beginning of
        the input.

     -number
        Copying begins at distance -number from the end of the
        input.  Number is counted in units of lines, 1024-byte
        blocks or characters, according to the appended option l,
        b or c, respectively.  When no units are specified,
        counting is by lines.  When the size argument is not
        specified, the last 10 lines are copied.

EXAMPLES
     The following example reads the output from nroff(1) which
     is being written to the file text.out. The last 30 lines of
     output are displayed first, and then all subsequent output
     is displayed.

          nroff file > text.out&
          tail -30lf text.out

     This example builds a new copy of the file example
     containing all but the first 29 lines of the original copy.
