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 (powers of 1024) or KB,MB,... (powers of
1000). Binary prefixes can be used, too: KiB=K, MiB=M, and so on.
- 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
