SPLIT(1)                                                 SPLIT(1)

          split - split a file into pieces

          split [ -n ] [ file [ name ] ]

          Split reads file and writes it in n-line pieces (default
          1000), as many as necessary, onto a set of output files.
          The name of the first output file is name with aa appended,
          and so on lexicographically.  If no output name is given, x
          is default.

          If no input file is given, or if - is given in its stead,
          then the standard input file is used.
