Dear,

I want to composite 2 images and save them with the name of the first image and the letter F
But: one of the 2 images, must be the newest image in the folder list ( according to image build date in the folder ), and this image name , must also be the final saving image with "F" behind the image name.

So i have this command in the particular folder: composite -gravity north "20180614_120000_SQM-LE SN-3515-N-XXX-Observatory Gromme.png" SQM.png "20180614_120000_SQM-LE SN-3515-N-XXX-Observatory Gromme_F.png"

The file: "20180614_120000_SQM-LE SN-3515-N-XXX-Observatory Gromme.png" is the newest file in the list, so it must be put on "SQM.png"

But how can i now let it automatically take the newest image in the list and run the single command. ( Because every day the newest image changes by name) and then save it as the name of the newest file with _F behind.

For example this is how the list looks like:

Later on i will use Cron do run this single command, one time, every day around 10h UT, so it takes always the newest file

Thank you.
