NAME
       split - split a file into pieces

SYNOPSIS
       split [OPTION]... [FILE [PREFIX]]

DESCRIPTION
       Output pieces of FILE to PREFIXaa, PREFIXab, ...; default size is 1000 lines, and default PREFIX is 'x'.

       With no FILE, or when FILE is -, read standard input.

       Mandatory arguments to long options are mandatory for short options too.

       -a, --suffix-length=N
	      generate suffixes of length N (default 2)

       --additional-suffix=SUFFIX
	      append an additional SUFFIX to file names

       -b, --bytes=SIZE
	      put SIZE bytes per output file

       -C, --line-bytes=SIZE
	      put at most SIZE bytes of records per output file

       -d     use numeric suffixes starting at 0, not alphabetic

       --numeric-suffixes[=FROM]
	      same as -d, but allow setting the start value

       -x     use hex suffixes starting at 0, not alphabetic

       --hex-suffixes[=FROM]
	      same as -x, but allow setting the start value

       -e, --elide-empty-files
	      do not generate empty output files with '-n'

       --filter=COMMAND
	      write to shell COMMAND; file name is $FILE

       -l, --lines=NUMBER
	      put NUMBER lines/records per output file

       -n, --number=CHUNKS
	      generate CHUNKS output files; see explanation below

       -t, --separator=SEP
	      use SEP instead of newline as the record separator; '\0' (zero) specifies the NUL character

       -u, --unbuffered
	      immediately copy input to output with '-n r/...'

       --verbose
	      print a diagnostic just before each output file is opened

       --help display this help and exit

       --version
	      output version information and exit

       The  SIZE  argument is an integer and optional unit (example: 10K is 10*1024).  Units are K,M,G,T,P,E,Z,Y,R,Q (powers
       of 1024) or KB,MB,... (powers of 1000).	Binary prefixes can be used, too: KiB=K, MiB=M, and so on.

   CHUNKS may be:
       N      split into N files based on size of input

       K/N    output Kth of N to stdout

       l/N    split into N files without splitting lines/records

       l/K/N  output Kth of N to stdout without splitting lines/records

       r/N    like 'l' but use round robin distribution

       r/K/N  likewise but only output Kth of N to stdout
