[arch-general] journalctl

hello, when I use journalctl to track system events, I introduce line breaks for better readability. like multitail, I would like to introduce more verbose line breaks... I wrote these few lines but it doesn't work as expected : 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 ? regards, lacsaP.
