Script not working in crontab
Hi

I have created a script. Which i have configured in cron to make it run in every 2 min. But script is not running. If I checl the cron log at /var/cron/log .it shows its running in every 2 min. Below is the command which i configured in crontab.

But I am not able to find the way so that this script can run in every two mins.

Code:
0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58 * * * * /appl/ESA/sigcheck.sh

Please suggest how to run this script in the cron.

Thanks in advance

Nandan

I don't think your crontab entry is the problem. You need to be sure that ALL the environment variables that make the script run from the command line exist in cron.

Example: you might need to source /etc/profile inside your script
Code:
. /etc/profile

You could also modify your cron entry to get errors into a log file

Code:
0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58 * * * *  /appl/ESA/sigcheck.sh 2>> /tmp/sigcheck.log

to see what is going on.

Hi Jim .Thanks for the reply. I did the same as u suggested.

content of /tmp/sigcheck.log are as follows.

Code:
resize:  can't open terminal /dev/tty
/appl/ESA/sigcheck.sh: C: not found
resize:  can't open terminal /dev/tty
/appl/ESA/sigcheck.sh: C: not found

Please suggest what need to do now. I am not able to understand about this error.

Thanks in advance..

and you might want to check if your cron allows for step values like */2 to execute a job every other minute...

Something in that script is demanding an interactive terminal.

Without seeing your code we can't possibly tell why.

Hi Corona

Please find below the script code..
Code:
#!/bin/sh
#set -x

checkMS()

{

 MSAlive=`ps -ef |grep java |grep -i "ms1@ipx.com" |grep -v grep |wc -l`

    if [ "${MSAlive}" -eq 0 ]; then
      echo "MS is down.. Please check "
      
      `$ESAHOMEINSTALL/ESA/bin/reportEvent raise APP 1 .1.1.1.3 "Messaging Server Down"`

      else
            MSCheck=`$ESAHOMEINSTALL/ESA/bin/printActiveAlarms | grep "Messaging Server Down" | wc -l`
          if [ "${MSCheck}" -eq 1  ]; then

	`$ESAHOMEINSTALL/ESA/bin/reportEvent clear APP 1 .1.1.1.3 "Messaging Server Down"`

	else
               echo " "

	fi

    fi

}

checkTS()

{

 TSAlive=`ps -ef |grep java |grep -i "Name=traf_svr" |grep -v grep |wc -l`

    if [ "${TSAlive}" -eq 0 ]; then
      echo "TS is down.. Please check "

      `$ESAHOMEINSTALL/ESA/bin/reportEvent raise APP 2 .1.1.1.3 "Traffic Server Down"`

      else
            TSCheck=`$ESAHOMEINSTALL/ESA/bin/printActiveAlarms | grep "Traffic Server Down" | wc -l`
          if [ "${TSCheck}" -eq 1 ]; then

        `$ESAHOMEINSTALL/ESA/bin/reportEvent clear APP 2 .1.1.1.3 "Traffic Server Down"`

            else

               echo " "
        fi

    fi

}



checkSIGNode()
{
checkMS
checkTS

}
