Indeed, I've got the 3>&1 in the wrong place. Sorry about that.
} In zsh, to avoid the multios effect, you can do:
}
} {strace -o /dev/fd/3 ./a.out 3>&1 > out.log 2> err.log} | less
}
} or disable multios (set +o multios).
With multios and without the braces, out.log gets the a.out output
and less gets both the strace output and the a.out output, which is
actually what I meant to do (but might not be exactly what Nathan
wanted, in retrospect). Thanks for the correction.
