Maybe this whole thing is solved by going directly to the stream solution?
$ rlwrap ./factor -run=listener 2> /dev/null
IN: scratchpad USING: io.encodings.utf8 io.launcher ;
IN: scratchpad "find /home/alex/talks/factor -name *.pdf" utf8 [ lines
] with-process-reader .
{
"/home/alex/talks/factor/factor.pdf"
"/home/alex/talks/factor/factor-test.pdf"
}
IN: scratchpad "find /home/alex/talks/factor -name DOESNOTEXIST" utf8
[ lines ] with-process-reader .
{ }
IN: scratchpad "find /proc -name PERMISSION_DENIED_ERROR" utf8 [ lines
] with-process-reader .
Process exited with error code 1

Type :help for debugging help.
See
- http://docs.factorcode.org/content/word-with-process-reader%2Cio.launcher.html
- http://docs.factorcode.org/content/word-lines,io.html
- General perusal of
http://docs.factorcode.org/content/article-io.launcher.html and
http://docs.factorcode.org/content/vocab-io.launcher.html
As for the original problem of I/O redirection, there seem to be some
docs on that at
http://docs.factorcode.org/content/article-io.launcher.redirection.html
and some examples in
http://docs.factorcode.org/content/article-io.launcher.examples.html
Hope that helps,
