I'm looking to have a Folder to trigger an action when a file is added, how do I then pass that filename onto the applescript?
My initial response is "Use Hazel" but I presume that isn't what you're looking for.
The only way that I can think of is to use a shell script to get the most recently changed file in the directory.
ls -1rt /path/to/your/folder | tail -1
which will get you something like
Note that it will not include the folder path, just the file name.¹
Save the output of that shell script to a variable, and then you can use the variable in AppleScript.
(There's probably a way to do that in AppleScript too, but I don't know AS well enough to know what it is.)
¹ it also occurs to me that this will just give you the most-recently-modified file, which may not be the most-recently-ADDED file. For example, imagine that you made a file on Monday called "~/Desktop/test1.txt" and then a file on Tuesday called "~/Documents/test2.txt". If you moved
test1.txt to the ~/Documents/ folder,
ls -1rt ~/Documents/ | tail -1 will give you
Then there's the question of what do you do if the most recently added file is a folder. Do you want to take the same actions?
I tend to get around this by having "Files That I Want To Do Something Special To" all go to ~/Action/ which is where they are acted upon and then the final action is moving them to a different folder, so that ~/Action/ is (for all practical purposes) always empty, so whatever file / folder is in there is the only one that I need to act upon. Then I can either use Hazel or
launchd to monitor that folder for changes.
I stick by my initial answer of "Use Hazel" as probably being the best/easiest solution.
I did find this,
Not working for me, but it does know what file triggered the action, unfortunately, it's not then running in a script.
I don't think applescript can run the recently added, only created and modify dates.

### Requires Keyboard Maestro 8.0.3+ ### set kmInst to system attribute "KMINSTANCE" tell application "Keyboard Maestro Engine" set filePath to getvariable "Local__FilePath" instance kmInst end tell --- filePath is the POSIX path to the file/folder --- -- You may need to convert to Finder alias to use with Finder set fileAlias to POSIX file filePath as alias tell application "Finder" to open fileAlias
Perfect that it appears to work fine!! Thank you!
