redirecting output and input in mid job

[Dan Jacobson]

here's some ideas for your deluxe edition:
$ (while sleep 3; do echo o; done)&
$ fg -o file #exec job's 1> file
$ fg -a file #appends
$ bg -a file
$ bg \< file #or -i, or -fd 1, 2 , 0 etc. or /dev/stderr ...
etc. etc. i.e. redirecting output and input in mid job.
or something like that.  in case you can't do this already.
