I've got a pretty simple webhook script that I use to post to a Slack channel when an event triggered by Hazel starts and another when it ends.

Is there a way to get the file size of the file triggering the Hazel rule that I can use in my embedded script? (The script is running Handbrake on the file, so I'd like to see its size before and after in Slack, so I know how much size I saved).

There is the "Size" attribute. I'm not exactly sure how you are communicating with Slack though so can't say much more than that.

The Slack script is just a webhook, like this:

Code: Select all

LONG_FILENAME="$1"
curl -X POST --data-urlencode "payload={\"channel\": \"#handbrake-processing\", \"username\": \"Handbrake Bot\", \"text\": \"*$(basename $LONG_FILENAME)* has started processing.\", \"icon_emoji\": \":arrow_forward:\"}" https://hooks.slack.com/services/XXXX/XXXX/YYYY

Since I'm using the embedded script, I don't see an option to use the "Size" attribute. Is there some method like the LONG_FILENAME="$1" bit I'm using? (I found that on the forum last week.)

If you're using a shellscript you can't pass any info from Hazel to it besides the file path. Instead, you can use a command in the shellscript to get the size. Probably some combination of "ls" and "awk" can do that.

What's the right syntax to have it run the ls command?

I tried

Code: Select all

FILESIZE=`ls -l --block-size=M`

and it's not outputting anything correctly.

I tried regular quotes, no quotes, and single quotes. None gave me any output.

You can do "man ls" on the commandline to see all the options. Also note that you need to include "$1" as that is the argument which contains the path to the file that Hazel sends in to your script.

My command in Terminal works perfectly. I just don't know how to make it work in Hazel.

This is what I'm doing now:

Code: Select all

LONG_FILENAME="$1"
FILESIZE=`ls -lh *.mp4 $1`
curl -X POST --data-urlencode "payload={\"channel\": \"#handbrake-processing\", \"username\": \"Handbrake Bot\", \"text\": \"*$(basename $LONG_FILENAME)* has started processing. It started as $(basename $FILESIZE)\", \"icon_emoji\": \":arrow_forward:\"}" https://hooks.slack.com/services/XXX/YYY/ZZZ

In terminal I get the right size for my .mp4 (which is what I'm targeting). But in Hazel, it's running on the whole contents of the directory, which makes me think the

Code: Select all

FILESIZE=`ls -lh *.mp4 $1`

is wrong.

How do I pass that into Hazel? Quotes? Double Quotes? Triple Quotes? No quotes? That's what I can't find any documentation on.

You should probably use double quotes, or use the LONG_FILENAME variable which you already have set.
