How do I download a file to a newly created directory with curl on OS X? - bash

Question

I am trying to download my Heroku backups to a folder.
Downloading to the current folder like this works:
curl -o latest.dump `heroku pg:backups public-url`
But when I tried adding a folders path to latest.dump it looks like this:
$ curl -o /db-bkups/latest.dump `heroku pg:backups public-url`
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
0 44318 0 0 0 0 0 0 --:--:-- 0:00:01 --:--:-- 0Warning: Failed to create the file
Warning: /db-bkups/latest.dump: No such file
Warning: or directory
36 44318 36 16384 0 0 9626 0 0:00:04 0:00:01 0:00:03 9626
curl: (23) Failed writing body (0 != 16384)
Ideally, I would like it be saved and downloaded like this:
/db-bkups/nov-1-2016/timestamp-db.dump
Where the folder nov-1-2016 is created dynamically when the cron is run, and the filename is the timestamp when the bkup was run.

You could try using the --create-dirs argument which was added in curl 7.10.3:
Here is an example that will create the directory hierarchy, (if it doesn't already exist), and will name the subdirectory you require renamed with the output of the datecommand:
curl -o /db-bkups/$(date +"%b-%d-%Y")/timestamp-db.dump --create-dirs http://www.w3schools.com/xml/simple.xml
The result is a file stored in a directory like so /db-bkups/Nov-04-2016/timestamp-db.dump.
