Sorry if it does not belong to this list.
I want to write a pair of filters to convert between excel and uncompressed
gnumeric files,
my initial attempt is this script xls2gnm
ssconvert --import-type=Gnumeric_Excel:excel --export-type=Gnumeric_XmlIO:sax
fd://0 fd://1 | zcat
it is ok if invoked in the form
xls2gnm <a.xls >b.gnumeric
but it said broken pipe when invoked as pipe
cat a.xls | xls2gnm
to workaround, I need a temp file to hold the data
cat >/tmp/xls2gnumeric.tmp && ssconvert --import-type=Gnumeric_Excel:excel
--export-type=Gnumeric_XmlIO:sax /tmp/xls2gnumeric.tmp fd://1 | zcat
AFAICS it is not related to zcat. Did I miss something?

沙場烽火侵胡月 海畔雲山擁薊城 少小雖非投筆吏 論功還欲請長纓
