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

Create Captions From a Filename

The command alone will put the full filename in the comments. If you want to add the filename without the extension, add the example exiftool config file found here
# This is the command if you have the config installed
exiftool '-Comment<BaseName' '-UserComment<BaseName' .

# Getting the filename without the config file, but with a for-loop
for i in *; do 
	FileName="${i%%.*}"
	exiftool "-Comment=$FileName" "-UserComment=$FileName" "$i";
done

###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" .  

Rename Files to With Milliseconds

Good for burst photos where the seconds are all the same. If milliseconds are only out to 2 digits, use ${SubSecCreateDate} instead
Found at http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=2736.0
exiftool -v '-Filename<${datetimeoriginal}${subsectimeoriginal;$_.=0 x(3-length)}.%e' -d %Y%m%d_%H%M%S .

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
