How to generate a list of dates from the shell (bash)

Here is a shell script that will generate the dates of the monday’s within the given range. It requires bash and the GNU version of the date command (gdate in my case). Currently it works only if the date format allows to compare date by comparing strings, but you can easily adapt it if required.


start=`$DATE +$FORMAT -d "2013-05-06"`
end=`$DATE +$FORMAT -d "2013-09-16"`
while [[ "$now" < "$end" ]] ; do
  now=`$DATE +$FORMAT -d "$now + 1 week"`
  echo "$now"
