Last Sunday of the month with awk

Hi,

this is how to get last day of the month:
cal|awk 'END{print DAY};{if (NF<1) {next};DAY=$NF}'

Is there a similar way to get the last Sunday and last Friday of the month? Thanks in advance.

Thanks, but I need it for production machine in a corporation. A lot of compliance problems with a new scripts there and your advice is not feasible for me, but thanks.

What about awk version? No chance to do it that way?

But this *is* shell script:

cal|awk 'END{print DAY};{if (NF<1) {next};DAY=$NF}'

Piping output of cal into awk...

anyway if you want a quick and dirty method of doing this I guess something like:

cal | awk '{ print $6 }' | sed /^$/d | tail -1

would work for Friday, and obviously:

cal | awk '{ print $1 }' | sed /^$/d | tail -1

for Sunday
