Thread: kill both parent and child processes

hi,

running bash script background job. bash script calls time-consuming executable. if not wrong, running of bash script parent process , running of executable child process.

(1) when @ output of top, shows child process running of executable, not shows parent process running of script. wonder why not show both? , how show both?

(2) want stop whole running killing parent process background job

code:

kill -9 $(jobs -p)

the terminal shows running of bash script killed. running of executable still hangs on output of top. wonder how kill both parent , child process?

, regards!

i found script kills child processes given pid

code:

# script kill child process id  given pid  #store current process id  curpid=$$    # process id, parameter passed user  ppid=$1    if [ -z $ppid ] ;     echo no pid given.     exit;  fi    arraycounter=1  while true           forloop=false          # child process id          in `ps -ef| awk '$3 == '$ppid' { print $2 }'`                           if [ $i -ne $curpid ] ;                          procid[$arraycounter]=$i                          arraycounter=`expr $arraycounter + 1`                          ppid=$i                          forloop=true                  fi          done          if [ "$forloop" = "false" ] ;             arraycounter=`expr $arraycounter - 1`             ## want kill child process id first , parent id's             while [ $arraycounter -ne 0 ]                           kill -9 "${procid[$arraycounter]}" >/dev/null               arraycounter=`expr $arraycounter - 1`             done           exit          fi  done  ## kill parent id  kill -9 $curpid

i use kill -9 last resort.
start with:

code:

kill pid

wait few seconds
if still alive:

code:

kill -2 pid

wait few seconds
if still alive:

code:

kill -1 pid

now should dead , gone, there last, dirty resort:

code:

kill -9 pid

note, kill -9 cuts throat without giving sick process chance of cleaning after (sockets/temp/children a.o.)
