SPLIT(1)

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
