script to check/start process

Ahmed_58 — Thu, 17 Sep 2009 05:50:29 GMT

Hi,
I need a script to:
1. check a process "ps -ef | grep ecoc"
2. if display "/opt/vantage/bin/ecocComputer-p 1 -t 0"
3. OK, then exit.
4. else start/execute "/opt/vantage/bin/restart_ecoagt

thanks,
Ahmed

Hi,
quick & dirty and not tested but should give you an idea

#!/usr/bin/sh
ps -ef | grep eoc

If [ $? = 0 ]; then
exit 0
else
/opt/vantage/bin/restart_ecoagt
fi

better approach is to find exact pattern first:

instead of ps -ef | grep eoc use:
ps -ef | grep -w eoc

Hi,
It should like this

#!/usr/bin/sh
ps -ef | grep eoc
If [ $? = 0 ];
then

/opt/vantage/bin/ecocComputer-p 1 -t 0

else

/opt/vantage/bin/restart_ecoagt

fi

On second thought, that is better way:

ps -ef | grep -w ecoc | grep -v grep

Hi,
it looks the RC is always "0" as it is not excuting the else command to restart the process!

ps -ef | grep ecoc
#ps -ef | grep -w ecocComputer
if [ $? = 0 ]; then
echo ServerVantage is OK running with ecocComputer process...
else
/opt/vantage/bin/restart_ecoagt
fi

Hi Ahmed,

ps -ef | grep whatever
will in most cases return at least the process line for the grep command, and therefore you get "0".

Instead of
ps -ef | grep ecoc
try this line:
$(UNIX95= ps -C ecoc > /dev/null)

the space after the equal sign is important!

regards,
John K.
