split — split a file into pieces

TL;DR

split -l 10 {{filename}}

split -n 5 {{filename}}

split -C 512 {{filename}}

Synopsis

split [OPTION]... [FILE [PREFIX]]

Description

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
-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).

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
