[Bug-wget] Retrying/killing

[Paul Wagner]

Dear wgetters,

I'm trying to grab some webradio programmes with wget and have 
encountered two difficulties:

* First, my internet connection sometimes breaks, and I would like wget 
to retry as long as I don't kill it.  I tried wget --tries=inf 
--retry-connrefused, but that does not retry e.g. when the interface 
goes down (this is how I tested my script).  Am I missing something 
here?

* In order to have my script retry, I ended up with something like

function job() {
    i=0
    while true
    do
        i=$((i+1))
        wget -a "$name.log" -O "$name-$i.mp3" "$url"
    done &
    sleep $length
    kill $!
}

while true
do
    t=$(date '+%M %H')
    while read startmin starthour length url name
    do
        [[ $t == $startmin' '$starthour ]] && job &
    done < conf-file
    sleep 60
done

Interestingly, the 'kill $!' kills the loop, but wget is not killed, but 
lives on with init as parent process.  Not really understanding what is 
going on here I can only guess this 'detaching' of the wget-process 
happens because it's ignoring SIGHUP?  The only solution I could come up 
with is using 'ps' to find the PID of the wget that has the 
loop-subshell as PPID, then killing the loop, and then killing wget 
separately, but this is so ugly that I can't imagine that there is no 
neat solution.

(Apologies if this isn't the appropriate place for asking this, as it 
might actually be a bash-question.  Any other suggestions or remarks 
highly welcome, too.)

Kindest regards,

Paul
