I have a ubuntu server 12.10 which receives images from a camera by FTP, I receive the images in a directory with a fixed quote on the server and I need to delete the oldest images first, I would like to keep 1Gb free for new images.

I have followed this thread but cannot find the solution there.

autotrash would be a good command but I do not have gnome installed.

Does anybody have any suggestions?

    The question you linked has plenty of good solutions for this problem. Can you detail which one you tried and why it didn't work for you? If it's a server, a crontab entry would be the best. If you know the image reception schedule the easiest way is to delete all files older than X days, if you have images of approximately the same size coming in at regular intervals you can easily figure out the needed "age" so that you have about 1 GB free at all times. – roadmr Jan 31 '14 at 17:32

Your original question is "How to delete files and subdirectories by size and age". Use find:

This will delete all files under the current directory larger than 2 MB:

find ./ -size +2M -delete

This will delete all files created more than 7 days ago:

find ./ -ctime +7 -delete
