Newbie trying to get Hazel to run a rule

[james.v]

I'm trying to get Hazel to run a rule based on whether exiftool finds it has a particular keyword.

I'm already using Keyboard Maestro to add the keywords using the shell script.

Code Select Expand

/usr/local/bin/exiftool ^ "," -XMP:Subject="$KMVAR_Local_myexiftags" -overwrite_original -P "$KMVAR_Local_filePath"
But Hazel requires a boolean output and I don't know how to do that.



Can someone help?
I've been searching and found some stuff about regex but it doesn't help me generate the output that I need for Hazel.

Thanks in advance

From the exiftool application documentation:

EXIT STATUS
       The exiftool application exits with a status of 0 on success, or 1 if
       an error occurred, or 2 if all files failed the -if condition (for any
       of the commands if -execute was used).

... which I think is exactly what you need.  No?

Thanks. Yes. It's just that I don't think my code is right. I have a photo with the subject exif keyword "Summer" in the folder but it's not working (hard to work out what's going on inside Hazel). Is my shell script right?

Code Select Expand

exiftool $1 -if "$Subject=~/(^|, )Summer(, |$)/" -xpcomment="0"

You need to use single quotes in unix shells (read my sig).

Brilliant. It's now working (I think) but it generates another file called filename.png_original
As far as the shell script is concerned it's only meant to pop out a yes or a no, right?

Just writing that down I've realised that I guess those files are its 0s and 1s right?

You are setting -xpcomment="0" so the file is edited and this XPComment is added.

That sorted it. Thanks so much Phil
