Organize your Photos by Date Using Exiftool

Find all photos without date information

$ exiftool -filename -filemodifydate -createdate -r -if '(not $datetimeoriginal) and $filetype eq "JPEG"' .

Set last created and modified to a specific date

$ find . -name "*.jpg" | while read filename;
exiftool "-AllDates=1986:11:05 12:00:00" "$filename";
done

Copy of the originals will be created. Remove *.jpg_original if everything went fine or add -overwrite_original parameter.

Timeshift

by one year

$ exiftool "-AllDates+=1:0:0 00:00:00" .

Rename your files to contain the date and time

they will be suffixed with -N if they have the same date and time

$ exiftool '-FileName<DateTimeOriginal' -d "%Y%m%d_%H%M%S%%-c.%%e" *.jpg
$ exiftool '-FileName<DateTimeOriginal' -d "%Y-%m-%d %H.%M.%S%%-c.%%e" *.jpg

Copy your photos in a folder structure organised by datetime

exiftool '-Directory<CreateDate' -d ~/Dropbox/Photos/%Y/%y%m -r .

ReplayGain your music using mp3gain

ReplayGain is the name of a technique invented to achieve the same perceived playback loudness of audio files. Read more on Hydrogenaudio.

Set all files to 92db – this is the most used loudness now-a-days (it’s recommended also in Serato DJ software and most streaming platforms seems to use same value). You might want to use 89db if you are listening on a Hi-Fi system – in this case just ignore the -d 3 option.

The suggested loudness is ~89, so we add 3.

mp3gain -d 3 -c -p -r *.mp3

or

mp3gain -s r -d 3 -c -p -r *.mp3

-s r this will ignore the replaygain information already stored in the file

-c will ignore clipping warning, use -k to lower the gain to not clip

-p preserve original timestamp of files

-r gain per track (as opposed to per album), it’s good for collections, best of, etc.

recursively apply gain to all your mp3 files

  • it works also for file names with spaces
find . -iname '*.mp3' -print0 | xargs -0 mp3gain -d 3 -c -p -r
