Hi list, i've been bashing my head on this one for a long time so i'd like to know if someone could give me an hint on it. I'm writing a script to control how i use udpcast to install my machines. My problem is that when i try to use "read" (bash builtin), right after udp-sender complete his transfer (Transfer complete. Disconnecting ...), "read" cannot read from the keyboard and i'm having this error : read: read error: 0: Resource temporarily unavailable I even try to write my script in perl but "chomp" fail at the same place... I'm pretty sure that it is a File Descriptor problem but don't know how to solve it. I think the relevant udpcast code is in console.c but i'm not a C programmer so i don't understand very well how things or going out in this file. Thanks a lot! Tony
