Hello,

Can someone be kind enough to point me in the right direction, please. I am not coding literate (am an interior designer), so I am totally clueless.

After scavenging the web, I came up with the following concoction that works in the Terminal, but fails in Hazel:

Code: Select all

opentags=`echo $1 | sed 's/.*\[\([^]]*\)\].*/\1/g'`

for i in $opentags
do
    tag -a "$i" "$1"
done

assignedtags=`tag -tg $1|grep '^    '|cut -c5-|sort -u`

echo "$assignedtags" | while IFS= read -r line ; do /usr/local/bin/exiftool -overwrite_original_in_place -P -keywords+="$line" $1; done ; /usr/local/bin/exiftool -overwrite_original_in_place '-keywords<${keywords;NoDups(1)}' '-exif:xpkeywords<${iptc:keywords;NoDups(1)}' -P -d '%Y:%m:%d_%H:%M:%S' '-filename<${FileModifyDate;}_$FileName' '-filename<${GPSDateTime;}_$FileName' '-filename<${MediaCreateDate;}_$FileName' '-filename<${ModifyDate;}_$FileName' '-filename<${DateTimeOriginal;}_$FileName' "$1"


The first part works in Hazel. (I tried running it as a separate rule). Essentially, it grabs a part of the fileName[enclosed in sq. brackets] and passes it along to "tag" the file (https://github.com/jdberry/tag). As I am frequently required to also work in MS Windows, I made a habit of naming files like this: " fileName[tag1 tag2 tag3].ext "

The second part is supposed to take the file's macOS tags and write them as EXIF & IPTC tags to JPEG files. It also prepends the DateTimeOriginal to the fileName. It works on the command line but for some reason is failing in Hazel.

Please guide me.

Thanks so much, & to those reading this post, a Happy New Year!

Where did you get the script from? Also, can you go through the troubleshooting guide here? https://www.noodlesoft.com/kb/hazel-tro ... ing-guide/

That almost certainly means that there is a tool being used which is not in the default PATH for macOS.

Unfortunately macOS no longer makes it easy to set the default PATH for GUI apps, so you have to do it in each script.

Try adding this as the first line of your shell script in Hazel:

Code: Select all

PATH=/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin

Hello,

I referred to some 5-6 different threads on stackoverflow.com & the forums here, and put it together to do what I want. Like I said, its a concoction

I did go through the trouble shooting guide as recommended. The rules setup and other things seem alright. Here's how it looks: https://postimg.cc/8fPBJ5Gf

The first part works just fine. Specifically:

Code: Select all

theFile=$1
assignedtags=`echo $theFile | sed 's/.*\[\([^]]*\)\].*/\1/g'`
for i in $assignedtags
do
    tag -a "$i" "$theFile"
done


But when I add the succeeding ExifTool part, it doesn't seem to work. Specific line from Hazel.log:

Code: Select all

Shellscript exited with non-successful status code: 1

Thanks for offering to help, I added that line as 1st line of the script. This is the error shown in log file:

Turn on debug mode as described here: https://www.noodlesoft.com/kb/hazel-debug-mode/

After that, any output from the script should appear in the logs which might help here.

Thanks for the "debug" tip. Seems like Exiftools is quite particular about how filenames (with spaces) are passed on to it.

Also, I had to include "set LANG=en_GB.UTF-8" at the beginning of the script to make it work. I don't know why that was need by Exiftools, though.

Solution (For now, this seems to work):

Code: Select all

theFile=$1
set LANG=en_GB.UTF-8
<<COMMENT
Most of my files are named like this: " fileName[tag1 tag2 tag3].ext "
Below I extract the tags enclosed in [square brackets] and apply as Mac File Tags
COMMENT

opentags=`echo "$theFile" | sed 's/.*\[\([^]]*\)\].*/\1/g'`
if [[ ! -z "$opentags" ]]
then
for i in $opentags
do
    tag -a "$i" "$theFile"
done
fi

<<COMMENT
Below I extract any Mac File Tags and inject them as EXIF & IPTC tags.
COMMENT
assignedtags=`tag -NG "$theFile"`
/usr/local/bin/exiftool -P -overwrite_original_in_place -m -sep "," -keywords=$assignedtags "$theFile"
/usr/local/bin/exiftool -overwrite_original_in_place -m -P -xmp:all= -tagsfromfile @ -xmp:all "$theFile" && /usr/local/bin/exiftool -overwrite_original_in_place -m -P -sep ', ' '-keywords<${keywords;NoDups}' "$theFile"
/usr/local/bin/exiftool -m -P -overwrite_original_in_place -sep ', ' '-exif:xpkeywords<${iptc:keywords;NoDups}' "$theFile"
<<COMMENT
Below extract the oldest available file date from EXIF and prepend it to the fileName. If EXIF date info is not available, we take the Birth Date from the system and use it.
COMMENT
fmDate=`exiftool -FileModifyDate -d '%Y%m%d_%H%M%S' "$theFile"` ; fmDate=${fmDate#*:}
gpsDate=`exiftool -GPSDateTime -d '%Y%m%d_%H%M%S' "$theFile"` ; gpsDate=${gpsDate#*:}
modDate=`exiftool -ModifyDate -d '%Y%m%d_%H%M%S' "$theFile"` ; modDate=${modDate#*:}
oDate=`exiftool -DateTimeOriginal -d '%Y%m%d_%H%M%S' "$theFile"` ; oDate=${oDate#*:}
bDate=`stat -f "%SB" -t "%Y%m%d_%H%M%S" "$theFile"` ; bDate=${bDate#*:}
availableDates=""
for i in "$fmDate $gpsDate $modDate $oDate $bDate" ; do if [[ ! -z "$i" ]] ; then availableDates+="$i" ; fi ; done ; prependDate=`echo "$availableDates" | xargs -n1 | sort -g | xargs | head -n1 | awk '{print $1;}'`

/usr/local/bin/exiftool -P -m -overwrite_original '-FileName<'"$prependDate"'_$FileName' "$theFile"



Please let me know if the above code can be made better. I am an Interior Designer, so this is NOT in my domain of understanding. But I entirely depend on Tagging for storing and retrieving my files (not just images), and I deal with a LOT of images. So I need this functionality. Hope it helps someone else too.

Thanks a lot.

I had a similar issue (interestingly enough trying to do similar things). I wish I had seen your thread earlier
I also found out during my troubleshooting that using shell tools you install yourself, like exiftool or ffmpeg, worked better if you enter the full path in the script (e.g. /usr/local/bin/exiftool).
Specifying the PATH on the first line should have worked though…
