Thanks again. I think I finally managed to make the server update script works:
cp original.slf updated.slf
while [ 1 ] ; do
nice parallel --timeout 1000% --nonall -j0 -k --slf original.slf --tag
echo | \
sed -e 's#\t$##' -e '#\t#d' | \
nice parallel -k perl -ne
\"\\\$host=\'{}\'";\\\$host=~s#\\\\\##g;/^(\d+\/)?\\\\Q\\\$host\\\\E\\\$/ and
print and exit"\" original.slf > tmp.slf
if ! cmp -s tmp.slf updated.slf; then
mv tmp.slf updated.slf
fi
sleep 10
done &
parallel --slf updated.slf ...
Indeed, it is kind of ugly, but seems to get the job done (maybe it could be
simplified, though). Will you consider updating the manpage with this newer
version of the script?
I'll think about how to wrap those commands within a daemon, but first I need
to investigate why GNU Parallel is not respecting the number of slots on a host
when servers are dynamically included/excluded.
