Recently I was writing up my camping trip to Dartmoor and I wanted to transfer some photos from my phone to my computer.
A quick note on that first: since my phone is Android I have to use Media Transfer Protocol to transfer files.
There are a bunch of options to do so but I’ve found that simple-mtpfs is the easiest to use and doesn’t seem to go wrong.
To use it you simply plug in the USB cable with the phone attached, run
simple-mtpfs <mountpoint>, and voilà, you can now transfer files back and forth between devices.
To unmount just run
fusermount -u <mountpoint>.
Two commands you can use to view the metadata of image files are
The former can be used on any file type while the latter is specific to image files.
For the latter you can use either
identify <filename> on its own to get all of the image’s associated metadata, or you can use, for example,
identify -format "%w %h" <filename> to get just the dimensions of the image.
