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";
Copy of the originals will be created. Remove *.jpg_original if everything went fine or add -overwrite_original parameter.
by one year
$ exiftool "-AllDates+=1:0:0 00:00:00" .
Rename your files to contain the date and time
they will be suffixed tith -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

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
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.
I am a fan of plain text, so I prefer using plain text mails whenever possible. Here is how you do it for Apple Mail ( OS X El Capitan, but probably works on most versions).
Change the (default) format for all messages:
- go to Mail > Preferences, click Composing, then choose Plain Text as Message Format.
Change format of the current message:
- go to Format > Make Rich Text > Make Plain Text
Reply to messages in the same format you received them:
- go to Mail > Preferences, click Composing, then select Use the same message format as the original message
Most probably you will also want to use fixed-width font for plain text messages. So, go to Mail > Preferences > Fonts & Colors and choose Use fixed-width font for plain text messages
