Hello every body
goal: create a script that control periodicly ( every 30 min ) if a process is already actif.

How can I do that?

thanks

1- create a simple Script ver_proc.sh (in a apropiate directory example /usr/local/scripts/varios or /usr/local/sbin/varios)
#!/bin/ksh
if [ $# -ne 1 ]
then
echo "Usage: $0 <proc_name>"
fi
PROC_NAME=$1
DAY=`date +"%Y%m%d"`
TIME=`date +"%Y/%m/%d %H:%M"`
CURR_SCRIPT=$0
if [ ! -d /var/log/$DAY ]
then
mkdir /var/log/$DAY
chmod 0755 /var/log/$DAY
fi
OUT=/var/log/$DAY/ps_$DAY.txt
if [ `ps -ef |grep $PROC_NAME |grep -v $CURR_SCRIPT |grep -v grep |wc -l ` -eq 1 ]
then
echo "$TIME `/usr/ucb/ps vax |grep $PROC_NAME |grep -v $CURR_SCRIPT |grep -v grep`" >> $OUT
else
ps -ef |grep $PROC_NAME |grep -v $CURR_SCRIPT |grep -v grep | while read linea
do
TIME=`date +"%Y/%m/%d %H:%M"`
echo "$TIME $linea" >> $OUT
done
fi

exit 0

2- chmod 0755 /usr/local/scripts/varios/ver_proc.sh

3- create a cron Job.
EDITOR=/usr/bin/vi ; export EDITOR
cron -e
# add the following line
00,30 * * * * [ -x /usr/local/scripts/varios/ver_proc.sh ] \
/usr/local/scripts/varios/ver_proc.sh <proc_name>

4- Modify the script at your flavor

I would swear that this is a typical homework question. Could someone please close this post?

FYI to everyone. Especially newbies!

Please ask for more information about what the user is trying to do before shooting your wad with the complete answer.

Remember that oldie but goodie? Not mine but a great lesson.

GIVE a man a fish and feed him for a day.
TEACH a man to fish and feed him for a lifetime.

Sound like a reasonable request
