I'm trying to get SHA1 hashes from certain files. My embedded AppleScript is as follows:

Code: Select all: set shasum to do shell script "/usr/bin/shasum -a1 " & theFile set sha1 to text 1 thru 40 of shasum return {hazelPassesScript:true, hazelOutputAttributes:sha1}

But when I run it, it throws the following error:

2020-09-07 23:47:48.959 hazelworker[11302] payments-noreply_google.com.pdf: Rule SHA1 matched.

Could really use some pointers.

Have you tried running the script outside of Hazel?

Yes, I tried the script in Scripteditor.app prepended by

Code: Select all: set theFile to "/Volumes/{{local file}}.pdf

. That works fine.

Is that the same file being processed by Hazel? Also, there's a missing quote at the end of your example which reminds me that you may need to add quotes in your shell script around "theFile". You would probably need to escape them so that the AppleScript doesn't absorb them.

I managed to fix it another way. First, I take the file's full path as an inputAttribute. Then I feed that into the Shell script command. No need for escaped quotes and all that.

Code: Select all: set theFile to item 1 of inputAttributes set sha1 to do shell script "/usr/bin/shasum -a1 " & theFile & " | cut -d' ' -f1" return {hazelPassesScript:true, hazelOutputAttributes:{sha1}}
