Parallel instances

[m0nkge]

When running unoconv in a loop as follows everything works OK but its slow.

for i in *.odt ; do R=`unoconv --stdout -f text $i | grep -w "word" -c` ; echo $R $i; done

Attempting to speed it up, I spawned each iteration in the background.

LOG="/tmp/odtresults-`date  +'%Y%m%d%H%M%S'`.txt"
for i in *.odt ; do
        (
                R=`unoconv --stdout -f text  $i | grep -w -o "word" | wc -l`
                echo $R $i >>$LOG
        ) &
done

but this doesnt work as expected. I get a bunch of

Error: Unable to connect or start own listener. Aborting.

errors and a whole lot of stuck processes.

How can I get this to work?

Cheers.

Ok, I saw your note about starting the listener beforehand and I used your example.

adding

unoconv -l &
sleep 15s

fixes my problem. But I'd like to eliminate the 15s delay if possible. How can I know when the listener is ready?

I don't think you can. But a 15 second delay seems excessive? It's just a question of LibreOffice to start, does that take 15 seconds for you?

Unoconv does not support parallel instances. Unoserver might, in theory.
