If you find your self forgetting to empty the trash on a regular basis, why not automate it? The following applescript can be used to do just that.
tell application "Finder"
empty the trash
end tell
Alternatively, if you wanted to execute the cleanup from a shell script, or a one liner in your crontab, the following one liner could be utilized:
osascript -e ‘tell application “Finder” to empty the trash’
NOTE: In contrast to the command driven instructions represented in the Wikipedia article above, a nice GUI alternative is CronniX.
