Safe delete the files in shell to ./trash that can be restored later To use the scripts simple do the following
chmod +x sfrm
chmod +x unsfrm
chmod +x emptytrash
sudo cp sfrm /usr/bin/
sudo cp unsfrm /usr/bin/
sudo cp emptytrash /usr/bin/
This will add the sfrm,unsfrm and emptytrash to your command line and u can use them easily.
