# retis collect 2>&1 >/dev/null

# ls -alh /proc/$(pgrep retis)/fd/[1-2]
l-wx------. 1 root root 64 Jun 19 09:00 /proc/37517/fd/1 -> /dev/null
lrwx------. 1 root root 64 Jun 19 09:00 /proc/37517/fd/2 -> /dev/pts/0

As seen above, stderr is still pointed to the terminal and we see the output in the terminal.

# retis --version
retis v1.4.0 ("senyoret")

Sorry for the noise, I messed up the order of redirections...
