Shell Programming and Scripting

Cheers for the replies.

I have a few test things set up in the cron of a test UNIX box to see how they go, executing writing to files rather than running any backups.

Will see over the next few weeks. No rush to implement this in live environment.

Cheers,

Not exactly 21 will be on the fourth and 28 on the fifth.
I think this will do the job:

Code:

var=$(date +%j)
if [ $(date +%u) -eq 5 ] && [ $((($var / 7) % 4))$(($var%7)) -gt 30 -o $((($var / 7) % 4))$(($var%7)) -eq 0 ];then echo fourth week ;else echo regular week;fi

Yep but will start on Sunday

Hi again!

Still trying to get this to work, I have let it run for a while now and here is the results:

Code being run every Friday:

Code:

var=$(date +%j)

if [ $(date +%u) -eq 5 ] && [ $((($var / 7) % 4))$(($var%7)) -gt 30 -o $((($var
/ 7) % 4))$(($var%7)) -eq 0 ];

then echo Monthly Backup Ran >> /rab/testing.txt ;

else echo Weekly Backup Ran >> /rab/testing.txt;

fi

Output from testing.txt (note - I have manually added lines to this to keep track of dates):

Here you can see that the script is running once every 4 weeks, but it just falls on the wrong date.

So I'm guessing I need to offset the remainder it looks for (-eq 0) to something else? To offset it by 2 weeks. As it is out of sync by 2 weeks.

Tonight is a "Monthly backup" week(end).

Any ideas?
Cheers,
Rab
