So I wanted a way to organize my downloads folder by date, kind of like how Shiira does it, but will work with any file I through in there. So I wrote this bash script called organize_downloads:

#!/bin/bash

current=`current_workspace`
if ! [ -d $current ]
then
mkdir $current
fi
mv $HOME/Downloads/* $current

Where current_workspace is another bash script:

date +$HOME/Desktop/Workspaces/%m-%d-%y

I put these two scripts in ~/bin, which is in my path, and gave them the proper permissions. So now when I run organize_downloads, it moves everything in ~/Downloads to a folder of the form ~/Desktop/Workspaces/MM-DD-YY where MM-DD-YY is the current date.

To get organize_downloads to run every time a file hits ~/Downloads, I created a Launchd item:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>Label</key>
        <string>com.clofresh.organizeDownloadsByDate</string>
        <key>Program</key>
        <string>/Users/carlo/bin/organize_downloads</string>
        <key>ProgramArguments</key>
        <array>
                <string>/Users/carlo/bin/organize_downloads</string>
        </array>
        <key>ServiceDescription</key>
        <string>moves anything that is created in ~/Downloads to ~/Desktop/Workspaces/MM-DD-YY where MM-DD-YY is the current date</string>
        <key>WatchPaths</key>
        <array>
                <string>/Users/carlo/Downloads</string>
        </array>
</dict>

(I had to use the absolute path to my home directory because apparently ~/ doesn't work)

So I saved that plist as ~/Library/LaunchAgents/com.clofresh.organizeDownloadsByDate.plist and then ran launchctl load Library/LaunchAgents/com.clofresh.organizeDownloadsByDate.plist

And now I have a Workspaces folder on my desktop that organizes by date all my downloads and whatever I wanna throw in there!

The one problem I ran into so far is that I won't get prompted for overwriting a file. Maybe if I use mv -i and then somehow pipe the output into an Applescript alert? I'm not too familiar with Applescript, so someone help me out here.
