Is there an equivalent to the Mac OS X software Hazel that runs on Ubuntu?
"Hazel watches whatever folders you tell it to, automatically organizing your files according to the rules you create. It features a rule interface [..]. Have Hazel move files around based on name, date, type, what site/email address it came from [..] and much more. Automatically put your music in your Music folder, movies in Movies. Keep your downloads off the desktop and put them where they are supposed to be."
This question probably won't make sense unless you have used Hazel, but basically you can define rules via the GUI to move and rename files automatically to make an automated workflow.
