--additional-suffix=SUFFIX

-b, --bytes=SIZE

put SIZE bytes per output file

-C, --line-bytes=SIZE

put at most SIZE bytes of lines per output file

-d, --numeric-suffixes[=FROM]

--help

--version

output version information and exit

SIZE is an integer and optional unit (example: 10M is 10*1024*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 l/K/N output Kth of N to stdout without splitting lines r/N like 'l' but use round robin distribution r/K/N likewise but only output Kth of N to stdout
