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 out‐
       put 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.
