- Split a file, each split having 10 lines (except the last split):
split -l  [filename]
- Split a file into 5 files. File is split such that each split has same size (except the last split):
split -n  [filename]
- Split a file with 512 bytes in each split (except the last split; use 512k for kilobytes and 512m for megabytes):
split -b  [filename]
- Split a file with at most 512 bytes in each split without breaking lines:
split -C  [filename]
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)
- 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
- use numeric suffixes starting at 0, not alphabetic
- same as -d, but allow setting the start value
- -e, --elide-empty-files
- do not generate empty output files with '-n'
- 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/...'
- print a diagnostic just before each output file is opened
- display this help and exit
- 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).
CHUNKS may be:
- split into N files based on size of input
- output Kth of N to stdout
- split into N files without splitting lines/records
- output Kth of N to stdout without splitting lines/records
- like 'l' but use round robin distribution
- likewise but only output Kth of N to stdout
