Print photo at 4x6 when it appears in a folder

I'm trying to figure out a way to print photos at 4x6 automatically as they appear in a folder.

My conditions (which are working fine) are

"Date Last Modified is after Date Last Matched"
"Kind is Image"

I've found that the shell script

Code: Select all: lp -o media=Custom.4x6in filename.jpg

does exactly what I want, but I can't figure out how to pass the filename to the script in Hazel. I found a few posts on the forums suggesting something like

Code: Select all: LONG_FILENAME="$1" echo "Name with full path: $LONG_FILENAME" echo "Name with only filename: $(basename $LONG_FILENAME)"

But that doesn't seem to be working for me (I'm getting a "non-successful error code 1"). I tried printing the value of $1 to a file, and it seems that it's the actual image itself (I got a lot of gibberish) rather than the path to the image.

Does anyone have any suggestions?

You're on the right track, but you're missing quotes around LONG_FILENAME, so it would be something like this:

Code: Select all: lp -o media=Custom.4x6in $(basename "$1")

However, you probably don't need the basename here at all because lp can accept full file paths, so long as they are also quoted:

Code: Select all: lp -o media=Custom.4x6in "$1"

Note that the reason we have to do this is lp and other utilities separate their CLI commands by spaces, so effectively:

Code: Select all: lp -o media=Custom.4x6in "$1"

Becomes this:

Code: Select all: [0] -o [1] media=Custom.4x6in [2] "$1"

So, if you have spaces in your path of "$1", for example Showing you/a test/filepath name.jpg, you're actually asking lp to do this:

Code: Select all: [0] -o [1] media=Custom.4x6in [2] Showing [3] you/a [4] test/filepath [5] name.jpg

And it does not understand what the command "Showing" is, nor does it understand the file "Showing". That's why it'll fail unless you quote your spaces to give it:

Code: Select all: [0] -o [1] media=Custom.4x6in [2] "Showing you/a test/filepath name.jpg"

That's exactly what I needed. Thank you! Such a simple thing as putting quotes around it.

I want to lean that, can anyone tell me mor or give me a full sample , please
