===== Rename Photos to Metadata EXIF dates =====

jhead can do it! 

Its integrated in each linux distro's repositories, just install it with the package manager: 

  sudo apt install jhead             # debian & ubuntu style


Jhead can batch process many files at ones. This line renames all jpg files in the current directory to their creation dates, down to the second:

  jhead -autorot -nf%Y-%m-%d_%H-%M-%S *.jpg


This line creates filenames beginning with a sequence number, then the date and a common description:

  jhead -autorot -nf%03i_%Y-%m-%d_event-xy *.jpg

The result will look like this:

  001_2018-09-30_event-xy.jpg
  002_2018-09-30_event-xy.jpg
  ....


The EXIF metadata contains much more information, like camera model, lens, etc..
