I want to copy an existing working SD card to a newer, larger one.

Background: Following the recent discussions on SD card reliability, and
having had a couple of card failures on other Raspberry Pi systems, I
have now purchased a 32 GB card for my Raspberry Shake:

   https://www.amazon.co.uk/gp/product/B01BDKTQY6/

Currently the 'Shake has an 8 GB card so how would I go about
transferring the existing 8 GB card to the new 32 GB one?

I don't have access to a Linux systems with multiple SD card slots.

On Windows I would use Paragon's Hard Disk manager to transfer from one
HD to another and it would keep all the partitions intact but rescaled
to fit the new HD capacity.  I had considered using a Windows disk
imager program to copy the 8 GB card to a .IMG file and then writing
that image to the 32 GB card, but I don't know whether Linux would even
recognise the card, or be able to use its greater capacity.

If I could add a couple of SD card readers to a (different) Raspberry
Pi, is there a Linux command or program which do the equivalent of
Paragon's "copy disk and expand partitions"?  I'm not familiar enough
with Linux to know how to do this.
