NAME
split - split a file into pieces

SYNOPSIS
split [ -n ] [ -b byte_cnt ] [ file [ name ] ]

DESCRIPTION
Split reads file and writes it in n-line pieces or in byte_cnt byte
pieces to a set of output files. The default is in 1000 line
pieces. The name of the first output file is name with "aa"
appended, and so on, lexicographically, to "zz". If no output name
is given, "x" is the default, in which case split will create files
from "xaa" to "zzz".

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

BUGS
If you provide name, split can only create 676 separate files. The
default naming convention allows 2028 separate files.
