NAME
       split - split a file into pieces

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

DESCRIPTION
       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.
