hi ,

i'm running 2 similar script (ksh) under AIX , the first go normally out when i type "control c" :
ps before :
notes01 19882 38990 0 11:54:48 pts/0 0:00 recover -s cla0bkpe -d /base/base01 -t May 05 23:02:17 2005 -v -f -a /base/base01/mail/mail-01/xxxx.nsf
notes01 30866 40880 0 11:53:24 pts/0 0:00 -ksh
notes01 38990 30866 0 11:53:55 pts/0 0:00 ksh /exploit/sun/notes/notes-recover

ps after => nothing

and the pid is killed when the 2nd got his pid alive :

ps before :

notes02 21492 49230 0 13:47:40 pts/0 0:00 nsrnotesrc -s pcyyesvg -ZZ -X -t May 03 23:00:26 2005 -d /base/base02 /base/base02/mail/mail-01/xxxx.nsf
notes02 39506 42214 0 11:20:11 pts/0 0:00 -ksh
notes02 49230 39506 1 13:47:11 pts/0 0:00 ksh /users/notes02/scripts/sad/util/notes_restaure.ksh

ps after :

notes02 21492 1 0 13:47:40 pts/0 0:00 nsrnotesrc -s pcyyesvg -ZZ -X -t May 03 23:00:26 2005 -d /base/base02 /base/base02/mail/mail-01/xxx.nsf




the first script extract:

..............
recover -s ${NWServ} -d ${Directory} -t "${NewDate}" -v -f -a ${Fichier} >> ${LOG} 2>&1 &
Pid=$!
x=0
while :
do
ps -u ${IDUSER} | grep -q "${Pid}"
[[ $? -ne 0 ]] && break
Result=$(ls -al ${Directory}/$(basename ${Fichier}) 2> /dev/null | awk '{print $5;}')
Result=$((${Result}*100/${Size}))
x=${x}+1
Sigle=$(print $((${x}%4+1)) | awk '{print substr("|/-\\",$1,1);}')
[[ ${TTY} -eq 0 ]] && (tput sc;printf "%s %s %%" ${Sigle} ${Result};tput rc)
sleep 1
done

..............

the second script extract:

.............

nsrnotesrc -s ${NWServ} -ZZ -X -t "${NewDate}" -d ${Directory} ${Fichier} >> ${LOG} 2>&1 &
Pid=$!
echo " PID"
echo $Pid
echo ""
x=0
while :
do
ps -u ${IDUSER} | grep -q "${Pid}"
[[ $? -ne 0 ]] && break
Result=$(ls -al ${Directory}${Fichier} 2> /dev/null | awk '{print $5;}')
Result=$((${Result}*100/${Size}))
x=${x}+1
Sigle=$(print $((${x}%4+1)) | awk '{print substr("|/-\\",$1,1);}')
[[ ${TTY} -eq 0 ]] && (tput sc;printf "%s %s %%" ${Sigle} ${Result};tput rc)

sleep 1
done
..........


Why in the second one , the script go out and the pid attached to the "1" father ?

Where is the mistake ?

thanks in advance

It looks like nsrnotesrc is ignoring INTR. Any program can do that. It parent is not ignoring INTR. So the parent dies and the child survives. When a parent dies, the process is inherited by init.

Is INTR a flag or a command ?

In my case , is there any solution except killing manually the process ?

thanks
Christian

INTR is a signal. It is what gets sent to the processes when you type cntl c. The only other solution is to ask the author of nsrnotesrc to modify it so it does not ignore INTR.

Thanks again for your help

Christian
