How's the right way to pipe stdout & stderr from ping into an awk program? [duplicate]
This question already has an answer here:
Piping both stdout and stderr in bash?

Here's an excerpt of some commands that I've been trying to evaluate from a Zsh script:
cmd="ping -qc 3 -W 5 8.8.8.8 | xargs -0d 'n' awk -f presetup/testping.awk 2>&1"
print -r $cmd
output=$(eval $cmd)
print $output
I don't know what I'm missing but, all I'm trying to do is to process the stderr & stdout of ping with a single awk script. Here's the output I'm getting:
awk: presetup/testping.awk:6: fatal: cannot open file `PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.' for reading (No such file or directory)
The program is supposed to parse each output line of the ping command and match with regular expressions its output. Any ideas of what I'm missing?

@karakfa, thanks for your input. I removedxargs
and tried this:ping -qc 3 -W 5 8.8.8.8 2>&1 awk -f presetup/testping.awk -
without success. I had the following output:ping: -: Name or service not known

@karakfa, nevermind, I found it. The right way seems to be the following:ping -qc 3 -W 5 8.8.8.8 | 2>&1 awk -f presetup/testping.awk -
Thanks for pointing me into the right direction!

Thank you so much for pointing me into the right direction @karakfa. It seems that the right way is as follows:
ping -qc 3 -W 5 8.8.8.8 | 2>&1 awk -f presetup/testping.awk -
CORRECTION, redirect stderr to stdout, then pipe stdout to awk:
ping -qc 3 -W 5 8.8.8.8 2>&1 | awk -f presetup/testping.awk
OR:
ping -qc 3 -W 5 8.8.8.8 |& awk -f presetup/testping.awk
Thanks @tripleee!
