$0 [OPTIONS] FILE [FILE ...] Split FILE into
fixed-size pieces.
The pieces are 10 lines long,
if FILE is a text file.
The pieces are 10 kiB long,
if FILE is *not* a text file.
The last piece may be smaller, it contains the rest
of the original file.
The output files bear the name of the input file
with a 4-digit numerical suffix.
The original file can be reconstructed with
the command ``cat FILE.*´´
EXAMPLE:
splitfix.sh foo.pdf
splits foo.pdf into the files
foo.pdf.0000 foo.pdf.0001 etc.
splitfix.sh [-h | --help] This help text
splitfix.sh --version Print version number
OPTIONS:
-h
--help this help text
-s SIZE size of the pieces
in lines (for text files)
or in bytes (for other files)
