Du hast die Kamera so eingestellt, dass sie JPG + RAW fotografiert … und jetzt willst Du die Bilder nach Datum + Uhrzeit umbennennen. Ausserdem sollen alle schon entstandenen Metadateien (XMP) auch noch gleich umbenannt werden.

Aufruf: exipicrename *.JPG

eine umfangreichere neuere Version dieses Scripts mit bash und exiftool gibt es auf github

und eine noch schönere (und wesentlich schnellere) Variante mit python3 gibts auch auf github: exipicrename2

#!/bin/bash 
 
# exipicrename
 
# rename image files after their exif creation date and time
# AND also rename orf (raw) + xmp (metadata) files with the same new name
 
# if there are images created with the same date+time (more than one
# image per second) add a counter to the name (avoid overwriting).
 
# requires package "exiftool"
# requires package "dateutils" for dateconv
 
 
# parts of filenames
# if there is also a raw file to this jpg, add :
alsoraw=ar
# if the file is a doublicate, mark it with:
duplicatemarker=_DOUBLE_
