Crontab help

Shell Programming and Scripting
1

Hi Guys,

This is a line in my crontab.

07 15 24 11 6 /usr/local/dsadm/dsprod/src/run_ipoval.sh 2>&1

I understood as the script is to run on 24 of nov at 3 07 pm.
But the script is running on every sat at 03 07 pm.

could anyone help me out with this and clarify my doubt??

Thanks for ur help in advance,
Magesh

The last field (in red above) is what is causing it to run every saturday. That is the "day of the week" field. Setting it to * should do what you require.

But still i want to know in case if i give the above code as it is??

07 15 24 11 6 /usr/local/dsadm/dsprod/src/run_ipoval.sh 2>&1

The syntax is:

            - - - - -
