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

Create output files containing consecutive or interleaved sections of input

Options

--bytes=<SIZE>, -b <SIZE>

put SIZE bytes per output file

--line-bytes=<SIZE>, -C <SIZE>

put at most SIZE bytes of lines per output file

--lines=<NUMBER>, -l <NUMBER>

put NUMBER lines/records per output file

--number=<CHUNKS>, -n <CHUNKS>

generate CHUNKS output files; see explanation below

--additional-suffix=<SUFFIX>

additional SUFFIX to append to output file names

--filter=<COMMAND>

write to shell COMMAND; file name is $FILE (Currently not implemented for Windows)

--elide-empty-files, -e

do not generate empty output files with '-n'

--numeric-suffixes, -d

use numeric suffixes instead of alphabetic

--suffix-length=<N>, -a <N>

use suffixes of fixed length N. 0 implies dynamic length.

--hex-suffixes, -x

use hex suffixes instead of alphabetic

--verbose

print a diagnostic just before each output file is opened

--io

--io-blksize

--help, -h

Print help information

--version, -V

Print version information

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.

Examples

Split a file, each split having 10 lines (except the last split):

split -l {{10}} {{path/to/file}}

Split a file into 5 files. File is split such that each split has same size (except the last split):

split -n {{5}} {{path/to/file}}

Split a file with 512 bytes in each split (except the last split; use 512k for kilobytes and 512m for megabytes):

split -b {{512}} {{path/to/file}}

Split a file with at most 512 bytes in each split without breaking lines:

split -C {{512}} {{path/to/file}}
