split utility reads the given
  file and breaks it up into files of 1000 lines each. If
  file is a single dash or absent,
  split reads from the standard input.
  file itself is not altered.
The options are as follows:
-a-bk’ is appended to the number, the
      file is split into byte_count kilobyte pieces. If
      ‘m’ is appended to the number, the
      file is split into byte_count megabyte pieces.-l-nIf additional arguments are specified, the first is used as the
    name of the input file which is to be split. If a second additional argument
    is specified, it is used as a prefix for the names of the files into which
    the file is split. In this case, each file into which the file is split is
    named by the prefix followed by a lexically ordered suffix using
    suffix_length characters in the range
    “a-z”. If -a
    is not specified, two letters are used as the suffix.
If the name argument is not specified,
    ‘x’ is used.
split utility conforms to IEEE Std
  1003.1-2001 (“POSIX.1”).
split command appeared in
  Version 6 AT&T UNIX.
The -a option was introduced in
    NetBSD 2.0. Before that, if
    name was not specified, split
    would vary the first letter of the filename to increase the number of
    possible output files. The -a option makes this
    unnecessary.
