split -- split a file into pieces

  Syntax
  ======

  split [ -l line_count ] [ -a suffix_length ] [ file [ name ] ]

  split [ -b n[k|m] ] [ -a suffix_length ] [ file [ name ] ]

  split [ -line_count ] [ -a suffix_length ] [ file [ name ] ]

  Description
  ===========

  The split command reads file and writes it in as many n-line pieces as
  necessary (default 1000), 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.

  The following options are recognized:

  -line_count
          Specifies the number of lines in the resulting file.

  -a suffix_length
          Specifies that suffix_length letters are to be used to form the
          suffix portion of the filenames of the split files.

  -b n    Specifies that the file is to be split into n byte pieces.

  -b nk   Specifies that the file is to be split into n kilobyte pieces.

  -b nm   Specifies that the file is to be split into n megabyte pieces.

  If no input file is given, or if a dash (-) is given instead, the standard
  input file is used.

  Exit values
  ===========

  split returns 0 on success, 1 on failure.

  Examples
  ========

  Split the file testfile (124 lines long) into fileaa, fileab, and fileac
  (50, 50, and 24 lines long respectively):

  split -l 50 testfile file
