That was my first thought but then I read what was written and took
the | as a hint. The OP confirmed my guess though it is possible, I
suppose, that that was done mistakenly.

There is some sense in wanting to remove un-convertible files while
leaving those that do convert. Maybe the conversion is being done to
test the file's validity rather for its actual output.

Anyway, I think it helps that you've brought up the other option just in
case.

Something it tells me is that the OP's skills are rusty indeed,
either that or he didn't understand your question (2) above --
notice that what he actually typed was not the relevant command
followed by "echo $?" but a single "echo" command.

(I'd second the advice to define a shell function, but that may
be too advanced .... )
