today=`date +%a`
if [ "$today" == "Mon" ]
then
monday=`date -dmonday +%Y%m%d`
else
monday=`date -dlast-monday +%Y%m%d`
fi
Is it the best way to set the “monday” variable with the date of the last monday?
actually your logic is not always setting “last monday”. if today is monday, you would get current date value.
I feel your logic is ok. however one thing you may concern about is,
%agive you a localized weekday name. from man page:there is another format
%u, you could use, to make your script more portable.
