Embedded shell script fails

I have a shell script (in /usr/local/bin) called 'mkvdts2ac3', whose function is to convert audio inside of MKV files. When I invoke it from a Terminal command, it works flawlessly. However, I can't get Hazel to invoke it.

In Hazel, I'm using 'Run Shell Script -> Embedded Script'. I'm using this argument, using /bin/sh:

Code: Select all: mkvdts2ac3 "$1"

This returns "Error processing shell script on file ...". I also tried a couple of other variations, such as:

mkvdts2ac3 $1 (no quotes around the file reference)
mkvdts2ac3 "$1" (with /bin/bash this time)
mkvdts2ac3 $1 (again, with /bin/bash)

I'm running Hazel 2.3.8 on OS X 10.6.7. Any advice on getting this to work?

Can you post the error from the logs? The only thing I can tell by looking at it now is that you may need to specify the full path for the mkvdts2ac3 program.

From ~/Library/Logs/Hazel/Hazel.log (with my username removed for privacy):

Sorry, should have been more specific. Go to the "Info" section and click on "View Log". Search for the file in question. If there was an error, it should hopefully give more information on the nature of the error.

Here's what I've got from the hazel.log file:

Code: Select all: 2011-04-27 15:41:59.959 (null)[0] nsa-sample.mkv: Rule MKV - DTS2AC3 matched. /var/folders/VC/VCBr+5fBGyKzdlt6H7bPzU+++TI/-Tmp-/hazelfolderwatch-1531: line 1: mkvdts2ac3: command not found 2011-04-27 15:42:00.030 hazelfolderwatch[1531] [Error] Shell script failed: Error processing shell script on file /Users/xxx/MKVs/nsa-sample.mkv.

So, my first guess seemed to be right. You need to specify the full path to the program. Hopefully, that should fix it.

OK... how do I go about doing that? I just tried putting /usr/local/bin mkvdts2ac3 "$1", but that failed too.

Try:

Code: Select all: /usr/local/bin/mkvdts2ac3 "$1"

Still a no-go. What should I be putting as the shell?

Is the program actually in /usr/local/bin? What's the error in the log this time?

Maybe you should post a screenshot of your script.

Here's what's in the hazel.log:

Code: Select all: 2011-04-27 16:53:12.527 (null)[0] nsa-sample.mkv: Rule MKV - DTS2AC3 matched. 2011-04-27 16:53:12.721 hazelfolderwatch[2801] [Error] Shell script failed: Error processing shell script on file /Users/briancashion/MKVs/nsa-sample.mkv.

The program is definitely in /usr/local/bin. Here's the output of "type mkvdts2ac3", as executed in Terminal:

Code: Select all: mkvdts2ac3 is /usr/local/bin/mkvdts2ac3

Here's the screenshot:

And for good measure, a Finder screenshot showing the mkvdts2ac3 command:

I think at this point you should email me. In the "Info" section, click on the "Contact Support" link. Attach the program and a sample file which it fails on. I'll see if I can replicate it here.

E-mail sent.

I have solved this exact problem offline with another user. See our solution here. (EDIT - only nine months late...)
