Has anyone a script that will check for the last friday of the month and if So run the monthly config backup or if not the usually daily config.

I am currently looking at hacking something together as I was just going to edit the crontab and comment and uncomment between daily and monthly.

I have a 10 tape run So a 2 week daily schedule but I to implement a monthly that will run on the last fridat of each month.

Is the "last friday of the month" a solid requirement or could it
be "the FIRST friday of the month" instead.

If yes:

===== cut here == Version 1
#!/bin/sh
# first friday of the month
if [ `date +%d` -lt 7 -a `date +%a` = "Fri" ]
then amdump monthly
else amdump daily
fi
====== cut here

====== cut here == Version 2, using one subprocess only
#!/bin/sh
# First friday of the month
case `date +%d%a` in
    [1-7]Fri) amdump monthly ;;
    *)  amdump daily ;;
esac
====== cut here


If the requirement is necessarily "the last Friday of the month"
the script becomes a little more complicated because the last friday
could fall in the fifth week of a month.
A python script is already posted, a shell script is here:

==== cut here ====
#!/bin/sh
# Last friday of the month
if [ `cal | awk 'NF >= 6 {print $6}' | tail -1` -eq `date +%d` ]
then amdump monthtly
else amdump daily
fi
====  cut here ===
