rmw (ReMove to Waste) is a safe-remove utility for the command line. Its goal is to conform to the FreeDesktop.org Trash specification and therefore be compatible with KDE, GNOME, XFCE, and others. Desktop integration is optional however, and by default, rmw will only use a waste folder separated from your desktop trash. One of its unique features is the ability to purge files from your Waste/Trash directories after x number of days.
rmw is written in C, open source, and has a GNU GPLv3 License.
Build instructions and a detailed list of features and usage are documented in the README.
