Run a command for blocks of output of another command

tail -f /var/log/messages | while read line; do accu="$line"; while read -t 1 more; do accu=`echo -e "$accu\n$more"`; done; notify-send "Syslog" "$accu"; done
The given example collects output of the tail command: Whenever a line is emitted, further lines are collected, until no more output comes for one second. This group of lines is then sent as notification to the user. You can test the example with logger "First group"; sleep 1; logger "Second"; logger "group"
