stderr,which means that all handles for relations etc week be open in your script. If you e.g. do any unusual
redirections(2>&17 or such), that could end badly. But I'm just on my phone, in a taxi without seatbelts, at 60mph,
soI didn't look carefully.
gotcha :-). see above:
*) sqshf:
#!/bin/bash
cat \ $2 \ | eval "sqsh $1 -L'datetime=%Y-%m-%d %H:%M:%S.%u' -G 7.0"
echo "Success"
*) shexec:
#!/bin/bash
eval $1
FWICT that's all that's happening here with respect to pl/sh. I'm
almost done with reproduction environment and if i get the issue I
should be able to zero in on the problem. One final thing is that
concurrency is a contributing factor.
