After I debuged it, I found the codes in the lib/rancid/rancid.pm will result in the 'rancid' script doesn't show the error message (the missing cmd: xxx).

that implies to me that it did see the command (match it), but the filter
function exited with non-zero before it finished consuming the input.
Does that match your debugging?  Perhaps you can share an example with me
directly?
