NAME
split - Create output files containing consecutive or interleaved sections of input
SYNOPSIS
split [-b|--bytes] [-C|--line-bytes] [-l|--lines] [-n|--number] [--additional-suffix] [--filter]
[-e|--elide-empty-files] [-d ] [--numeric-suffixes] [-x ] [--hex-suffixes] [-a|--suffix-length] [--verbose]
[-t|--separator] [-h|--help] [-V|--version] [input] [prefix]
DESCRIPTION
Create output files containing consecutive or interleaved sections of input
OPTIONS
-b, --bytes
put SIZE bytes per output file
-C, --line-bytes
put at most SIZE bytes of lines per output file
-l, --lines [default: 1000]
put NUMBER lines/records per output file
-n, --number
generate CHUNKS output files; see explanation below
--additional-suffix [default: ]
additional SUFFIX to append to output file names
--filter
write to shell COMMAND; file name is $FILE (Currently not implemented for Windows)
-e, --elide-empty-files
do not generate empty output files with '-n'
-d use numeric suffixes starting at 0, not alphabetic
--numeric-suffixes[=]
same as -d, but allow setting the start value
-x use hex suffixes starting at 0, not alphabetic
--hex-suffixes[=]
same as -x, but allow setting the start value
-a, --suffix-length
generate suffixes of length N (default 2)
--verbose
print a diagnostic just before each output file is opened
-t, --separator
use SEP instead of newline as the record separator; '\0' (zero) specifies the NUL character
-h, --help
Print help
-V, --version
Print version
[input] [default: -]
[prefix] [default: x]
EXTRA
Output fixed-size pieces of INPUT to PREFIXaa, PREFIXab, ...; default size is 1000, and default PREFIX is 'x'. With
no INPUT, or when INPUT is -, read standard input.
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 splitโ
ting 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
