Hello,
I'd like to have output of socat commands in my shell script.
Currently, I log in to socat by using, for example:
socat - UNIX-CONNECT:/run/knot-resolver/control/1
There, I can issue cache.stats() and read it.
How can I have output these commands in shell script?
Appreciate your help.

It comes over the socket... so you can read it, but we recommend tojson
for scripts, e.g.:
output="$(echo "tojson(cache.stats())" | socat -
/run/knot-resolver/control/1)"
There's the inconvenience of "> " occurrences meant for interactive use
of the control socket, but it shouldn't be too hard to trim in the script.

Thanks Vladimir!
That worked fantastically.
I used:
output="$(echo "tojson(cache.stats())" | socat -
/run/knot-resolver/control/1 | cut -c 3- | rev | cut -c 1- | rev)"
echo $output | jq .
And it parses everything beautifully. I can now implement things into my
bots.
Kind regards,
Piotr
