Updated script for Leopard
Authored by: carmst on Feb 10, '09 06:27:41AM
After I upgraded to OSX 10.5 I had to update this script, because 10.5 was killing it halfway through if too many small files were in the trash, probably due to too much disk I/O. The old version admittedly was grossly inefficient, so criticism accepted, Leopard. :)

The version below now only gets the size of the Trash folder once, instead of after every file is deleted. There's also some logging and a retry with admin privileges if a stubborn file fails to delete.


on adding folder items to this_folder after receiving added_items
	
	set sizeLimit to 2048
	
	try
		tell application "Finder"
			set theSize to (size of (this_folder)) / (1024 ^ 2)
			repeat with thisItem in added_items
				set modification date of thisItem to (current date)
			end repeat
		end tell
	end try
	logConsole("TrashControl: Trash is using " & theSize & " of " & sizeLimit & " MB.")
	
	do shell script "ls -tr " & (quoted form of (POSIX path of this_folder))
	set theFiles to paragraphs of result
	
	set i to 1
	repeat while theSize is greater than sizeLimit
		
		set oldestFile to alias ((this_folder as text) & (item i of theFiles))
		try
			set theSize to theSize - ((size of (info for oldestFile)) / (1024 ^ 2))
		end try
		
		logConsole("TrashControl: Deleting " & quoted form of (POSIX path of oldestFile))
		set sh_script to "rm -Rf " & quoted form of (POSIX path of oldestFile)
		try
			do shell script sh_script
		on error errmsg
			set dialogmsg to "File failed to delete. Retry as Admin?"
			display dialog dialogmsg
			do shell script sh_script with administrator privileges
		end try
		set i to i + 1
		
		logConsole("TrashControl: Trash is using " & theSize & " of " & sizeLimit & " MB.")
	end repeat
	
	logConsole("TrashControl: Trash is under control at " & theSize & " MB.")
end adding folder items to

on logConsole(logMsg)
	set shellCommand to "logger" & space & quoted form of logMsg
	do shell script shellCommand
end logConsole
