PACKAGE_NAME Monthly Parity Check
PACKAGE_DESCR This package installs a script that will schedule a monthly parity check on the 1st Tuesday of the month at 6:30AM.
PACKAGE_DESCR <br>Use <b>NOCORRECT </b>if you do not want parity to be automatically updated.
PACKAGE_DESCR <br>Use <b>CORRECT </b>if you do want it automatically updated.<br<br>
PACKAGE_DESCR It is recommended that you <b>NOT</b> automatically correct parity, since it might be a data drive that is in error,
PACKAGE_DESCR and the parity drive might be correct.  <br>Challenge is determining which is correct, and which is in error.
PACKAGE_DESCR unRAID normally assumes the data is correct and parity is wrong. Pressing the "Check" button on the web-interface
PACKAGE_DESCR will check <b>AND</b> update parity based on the data disks.

PACKAGE_MEMORY_USAGE Small

If you name it "first-tuesday-parity-unmenu-package.conf" and put it in /boot/packages it will appear as its own separate package in the package manager.  It is actually quite ingenious.  It will invoke the cron entry every day at 6:30 AM on the 1st through the 7th of the month.  On each day the test if the current day = "Tue" will be made.  The actual parity check will only occur on the Tuesday when the date string is matched.

Clever...

Edit: Oh sh...t

I accidentally edited the original post instead of quoting it...  (Why is the "modify" adjacent to the "quote")

I'll try to get back the old text... but not sure if possible. Probably in my cache.

Sorry....

Yes, you can just edit the .auto_install file

You are obviously not a beginner.  Nice use of the "date" command to get the first "Tuesday" 

You'll need to invoke the .auto_install once on the command line, or reboot to get it to be invoked.

Just don't click on the "Re-Install on Re-Boot" button on the monthly-parity-check package again, or it will overwrite your changes.

No, I stole that from the code bank!

Thank you.

Hello again.

When using 'echo' and redirecting the output to a file, the date command executes no matter the quotes, how do I write what I want written to the file and not the result? ie:

echo "[ "$(date '+%a')" == "Tue" ]" >/tmp/test

result;

[ Sun == Tue ]

The desired result would be:

[ "$(date '+%a')" == "Tue" ]

Try

echo "[ \"\$(date '+%a')\" == \"Tue\" ]" >/tmp/test.sh

You just need to back-slash escape the quotes and $ special characters.

Thank You!

Just to let you know the cron job fired right on time - First Tuesday of the month.

Thanks again.
