Re: Last Pictures ID, how to retrieve it?

Note I'm not a developer and not a Linux specialist. This is the reason why I am asking your help.

Here are the two commands I use for the task explained in previous email:

# get the picture number

lastId=`gphoto2 --list-files | tail -2 | awk '{print substr($1, 2)}' | head -n 1`

# ... A few code lines to check and log the value of lastId

# download the file

gphoto2 --get-file $lastId --force-overwrite

Do you know a more efficient alternative skipping the long, very long, file list creation...?

Thank you.

Best regards,

Fred

Hi all,

I would like to know how can I easily catch the identifier (the picture number) of the last picture present on the memory card of the camera.

I do it actually using the "gphoto2 --list-files" command and capture the last ID communicated. But it is really long or completely unresponsive when more than 15000 pictures are stored on memory card.

I didn't see how can I do it easily.

Cameras used : Canon 100D and an old 400D.

The final goal of this is to download only the last picture and do a sort of supervision using the ID to count the number of pictures taken for example each day. I am doing really long timelapse...

Thank you in advance for your help.

Br,

Fred
