    hi folks

    I need to find out how to run a cron from 3:30am to 5pm every half hour.

    Is this correct?

    30, 3-17 * * */space/TEST/batch/bin/Schedule.sh >> /space/TEST/batch/bin/Schedule.sh

    Tried a quick google but still not sure

    thanks again!
    Trilla

    I think it would be something like:
    0,30 3-17 * * * /space/TEST/batch/bin/Schedule.sh

    My UNIX is a bit rusty, but will the last part not try to output the results of the script to the script itself?

    Yep, the redirect to the script will "append" the output of the script to itself.

    If you NEED to redirect, and dont care about the output, you could redirect to the bit-bucket (/dev/null). Explanation here.
    0,30, 3-17 * * * /space/TEST/batch/bin/Schedule.sh > /dev/null 2>&1
