I have to manage several streams! So I can't use killall?
Jörg, in my understanding, if darkice does not trap SIGPIPE, the killall line will always print "DI not running" (if there was only one instance, of course) - and if darkice does trap SIGPIPE, the script will never get to that point. Because then darkice will remain in foreground and the script will not advance. So this line can be simply dropped, I guess.
Second Question: To use additionally a logfile, I can write: darkice -c my.conf 3>&1 1>&2 2>&3> my.log And when I use your example: Blocks this my Terminal, when darkice run not in the background?
If you do not want to block the terminal, this script is not useful. You better log to file then. This is very simple: "$ darkice -c my.conf 2>&1 > my.log" - As Niels did suggest, a good idea, there are apps that monitor files for changes, I know "incrond, which is very flexible and lean on resource usage. Just start a new log file with every restart, so you dont have to count rows... Niels, do you listen?
Darkice code is very clean. The person who designed the ring buffer did something though, that I could not wrap my head around and modify to handle network congestion more gracefully. Fortunately I found edcast-jack back then. It also as its quirks, yet I dont look back. But kept subscribed to this list ;)
