Hi Pascal,
exec 6<&0 exec 0< <( while :; do read -sn1 k; echo $'\n'"# $( date +%H:%M:%S ) -------------------------------------------"$'\n'; done ) journalctl -f exec 0<&6 6<&-
the second instruction "exec 0< <( while..." played alone works perfectly in my terminal, but not as a redirection for journalctl. any leads ?
Don't you want to redirect journalctl's stdout into your while-loop, but you're changing the shell's, and thus journalctl's, stdin to come from the while-loop. exec 6>&1 exec 1> >(sed -n l) seq 3 exec 1<&6 6<&- -- Cheers, Ralph.
