      Hey Guys and Gals,

      Our Admin is out and I am trying to trouble shoot a bigger problem so I wrote a simple script that just starts a connection. I am trying to execute it from root’s cron. It executes fine when I just execute the script from the command line. I saw all the stuff about setting the environment variables, but then read that if you su – hci those should be set? Can anyone tell me what’s going on here? Any help would be appreciated as I have been fighting with this for some time now.

      Cron entry

      35 12 * * * 1,2,3,4,5 su – hci “-c /cloverleaf/qdx5.4.1/integrator/scripts/start_cer_law_usage”

      Error message in root’s mail

      Subject: Cron 1,2,3,4,5 su – hci “-c /cloverleaf/qdx5.4.1/integrator/scripts/start_cer_law_usage”

      X-Cron-Env:

      /bin/sh: line 1: 1,2,3,4,5: command not found

      Thanks,

      Tim

          Cron is expecting the 6th argument to be the start of the command.  It looks like you have too many asterisks and it is trying to execute the command ‘1,2,3,4,5’.

            Scott is right.  Here is an excerpt from the man page on crontab.

            The crontab File Entry Format

            A crontab file contains entries for each cron job. Entries are separated by

            newline characters. Each crontab file entry contains six fields separated by

            spaces or tabs in the following form:

            minute  hour  day_of_month  month  weekday  command

            These fields accept the following values:

            minute 0 through 59

            hour 0 through 23

            day_of_month 1 through 31

            month 1 through 12

            weekday 0 through 6 for Sunday through Saturday

            command a shell command

            Hope this helps,

              Thanks guys. That did the trick. Sometimes another set of eyes comes in handy.
