SPLIT(1) User Commands SPLIT(1)
split - split a file into pieces
split [OPTION]... [FILE [PREFIX]]
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
