SPLIT(1)							   User Commands							  SPLIT(1)

NAME

       split - split a file into pieces

SYNOPSIS

       split [OPTION]... [INPUT [PREFIX]]

DESCRIPTION

       Output  fixed-size  pieces  of  INPUT to PREFIXaa, PREFIXab, ...; default size is 1000 lines, and default PREFIX is 'x'.  With no INPUT, or
       when INPUT 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 lines per output file

       -d, --numeric-suffixes[=FROM]
	      use numeric suffixes instead of alphabetic; FROM changes the start value (default 0)

       -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 per output file

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

       -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

       SIZE is an integer and optional unit (example: 10M is 10*1024*1024).  Units are K, M, G, T, P, E, Z, Y (powers of  1024)  or  KB,  MB,  ...
       (powers of 1000).

       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 l/K/N   output Kth of N to stdout without splitting lines r/N	 like 'l' but use round robin distribution  r/K/N    like-
       wise but only output Kth of N to stdout
