##  rt/remove_trash.sh 

##  1. It is designed to replace old command rm without having to delete it.
##  2. It can avoid deleting files or directories with old command rm by mistake.
##  3. You can continue to use new 'rm' to delete files or directories, and it will move the target file or directory to
##     a trash directory instead of directly deleting them.
##  4. Besides, you can set the time to automatically empty the trash directory.
