tail(1)                    DG/UX 4.30                     tail(1)



     NAME
          tail - deliver the last part of a file

     SYNOPSIS
          tail [ +[number][lbc[f] ] ] [ 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 used.

          Copying begins at distance +number from the beginning, or
          -number from the end of the input (if number is null, the
          value 10 is assumed).  Number is counted in units of lines,
          blocks, or characters, according to the appended option l,
          b, or c.  When no units are specified, counting is by lines.

          With the -f (follow) option, if the input file is not a
          pipe, the program will not terminate after the line of the
          input file has been copied.  Instead, it enters an endless
          loop, wherein it sleeps for a second and then tries to read
          and copy further records from the input file.  Thus, you can
          use tail to monitor the growth of a file that is being
          written by some other process.  For example, the command:

               tail -f fred

          prints the last ten lines of the file fred, followed by any
          lines that are appended to fred between the time tail is
          initiated and killed.  As another example, the command:

               tail -15cf fred

          will print the last 15 characters of the file fred, followed
          by any lines that are appended to fred between the time tail
          is initiated and killed.

     SEE ALSO
          dd(1).

     BUGS
          Tails relative to the end of the file are saved in a buffer,
          and thus are limited in length.  Various kinds of anomalous
          behavior may happen with character-special files.

     WARNING
          The tail command will only tail the last 4096 bytes of a
          file, regardless of its length.
