Searching for Files

###Find images in a directory that don't have a DateTimeOriginal###

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

###Output photos that don't have datetimeoriginal to a CSV### Note this can take a long time if you have a lot of jpgs

# You'll need to set your Dropbox folder path. I have mine set as a global variable
OLDFILE="$DROPBOX_PERSONAL/nodates.csv"

FILECOUNT=$(mdfind -count -onlyin "$DROPBOX_PERSONAL" 'kMDItemKind =="JPEG image"')
while IFS= read -r -d '' n; do
    FILECOUNT=$(( $FILECOUNT - 1 ))
    if grep -q "$n" "$OLDFILE"; then
        echo "Skipping $n"
        continue
    fi

    echo -ne "Remaining: $FILECOUNT\r"
    exiftool -q -if '(not $datetimeoriginal or ($datetimeoriginal eq "0000:00:00 00:00:00"))' -csv -common "$n" | sed 1d >> "$DROPBOX_PERSONAL/nodates.csv"
done < <( mdfind -onlyin "$DROPBOX_PERSONAL" 'kMDItemKind =="JPEG image"' -0 )

###See files File Modify Date recursively in a directory who don't have datetimeoriginal set###

exiftool -filemodifydate -r -if '(not $datetimeoriginal or ($datetimeoriginal eq "0000:00:00 00:00:00")) and ($filetype eq "JPEG")' .

Modifying Files

###Change JPG to jpg and MOV to mov in filenames###

for i in *.JPG; do mv "$i" "${i%%.JPG}.jpg"; done; !#:gs/JPG/MOV/:gs/jpg/mov/

Recursively

find /path/to/directory -name *JPG -exec sh -c 'mv "$0" "${0%%.JPG}.jpg"; echo "Moved $0 to ${0%%.JPG}.jpg"' {} \;

###Change last created and modified for files in a directory###

The date syntax has to be YYYY:MM:DD HH:MM:SS

Option 1:

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

Option 2:

exiftool "-AllDates=1986:11:05 12:00:00" -if '$filetype eq "JPEG"' .

Timeshift Photos by One Year

Info at http://www.sno.phy.queensu.ca/~phil/exiftool/Shift.html

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

###Rename files to datestamp###

Filename looks like 2014-01-01 12:00:00.jpg and will append -NUM if DateTimeOriginal is the same for multiple files

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

Update any photo that doesn't have DateTimeOriginal to have it based on file modify date###

exiftool '-datetimeoriginal<filemodifydate' -if '(not $datetimeoriginal or ($datetimeoriginal eq "0000:00:00 00:00:00")) and ($filetype eq "JPEG")' .

Set DateTimeOriginal to Any Arbitrary Timestamp

exiftool '-datetimeoriginal=2015:01:18 12:00:00' .

Moving/Copying Files

###Copy directory recursively into organized folder###

exiftool -o ~/dummy/ -if '$filesize# > 300000' '-Directory<CreateDate' -d ~/Desktop/old_photos2/%Y/%m\ %B -r ~/Desktop/iPhoto\ Library/

-o ~/dummy This flag is to copy, not move. The directory is a fallback if the flag isn't available on the given photo. Good if using something like DateTimeOriginal

-if '$filesize# > 300000' gets files that are over 300kB. I was parsing an iPhoto library where there were thumbnails. The # turns the value to a number. you can use the flag -n to turn all values to numbers

'-Directory<CreateDate' Create directories based on the CreateDate of the photos

-d ~/Desktop/old_photos/%Y/%m\ %B Create folders with the given date format.

-r Run recursively

Extras

###Create KML from geotagged photos###

DESKTOP=$HOME/Desktop
cat $DESKTOP/kml-start.fmt > out.kml
exiftool -n -r -q -p $DESKTOP/kml-placemark.fmt . >> out.kml
cat $DESKTOP/kml-end.fmt >> out.kml

###Create CSV of Geo Information###

exiftool -csv -filename -imagesize -gps:GPSLatitude -gps:GPSLongitude ./ > long.csv
