Hi,
here is the current version (please find the script below). works on linux.
If you can check on mac or guide me to a solution...
ps -o pid= --ppid 1
ps -o pgid= --pid 1
Thank you.
PS: HBase, the big data solution for High Range Linux Servers or MacBook
only :-)
#get the list of the process considered as dead
# i.e.: in the same group as the script and with a ppid of 1
# We do this because surfire can leave some dead process, so
# we will jstack them and kill them
function createListDeadProcess {
id=$$
listDeadProcess=""
#list of the process with a ppid of 1
sonProcess=`ps -o pid= --ppid 1`
#then the process with a pgid of the script
for pId in $sonProcess
do
pgid=`ps -o pgid= --pid $pId | sed 's/ //g'`
if [ "$pgid" == "$id" ]
then
listDeadProcess="$pId $listDeadProcess"
fi
done
}
