Subject: Redirect a specific file descriptor to a pipe?
Date: Thu, 9 Mar 2017 17:21:31 -0700	[thread overview]
Message-ID: <CADgEyUsOZZZhiJM5JQrdHORt-ehoLJtYmwW8po4=LViuydMFiw@mail.gmail.com> (raw)

Hi,

It's easy to create an arbitrary file descriptor and redirect it to a
file, e.g. 3>foo. Is there any way to redirect it to a pipe instead of
a file?

For example (assuming Linux),

strace -o /dev/fd/3 ./a.out > out.log 2> err.log 3>XXX

Instead of file XXX, I'd like to send fd 3 to |less. Is it possible?

Many thanks.
