Im trying to parallelize websocket events, after searching a bit, i made a command like that

websocat "$URL" | env_parallel -k --lb --pipe -N1 parse-event

The problem is that every time, parallel waits for the first command to close before calling parse-event, even with --line-buffer

I tested if the problem was on parallel arguments, but with another input, it works exactly as i need it, spawning instantly as it reads the data

while true; do echo "test"; done | env_parallel -k --lb --pipe -N1 parse-event

And the websocat output alone is fine too, works normally on the terminal, other commands, and on a while read LINE loop

websocat "$URL" | xxd

Probably im missing something, what can be causing that?

The only command that i made that could replicate the issue was

(for x in {1..100}; do echo "$x"; done; sleep 100) | env_parallel -k --lb --pipe -N1 parse-event

shell-script shell gnu-parallel
