[code language="bash"]
Usage: split [OPTION] [INPUT [PREFIX]]
Output fixed-size pieces of INPUT to PREFIXaa, PREFIXab, ...; default
size is 1000 lines, and default PREFIX is `x'.  With no INPUT, or when INPUT
is -, read standard input.

Mandatory arguments to long options are mandatory for short options too.
-a, --suffix-length=N   use suffixes of length N (default 2)
-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  use numeric suffixes instead of alphabetic
-l, --lines=NUMBER      put NUMBER lines per output file
--verbose           print a diagnostic to standard error just
before each output file is opened
--help     display this help and exit
--version  output version information and exit

SIZE may have a multiplier suffix: b for 512, k for 1K, m for 1 Meg.
