If I open the properties window for some random file. If I click on the file icon in that window I can select a new preview image (thumbnail) for the file. This preview will be displayed in the file browser. How can do this from the command line?
(Because going through the gui to change file preview image takes a lot of time and clicking, I want to write a shell function or just an alias so that I can quickly change the preview of a couple of files in a directory)
man gvfs
