Where did you get this assignment?

There is no recycle bin on a shell level. A recycle bin (sometimes call a trash bin or something else, depending on what window manager you use), is a window manager concept that can be used to dispose of things attached to icons on your desktop.

The rm utility physically removes files; it does not move them to a recycle bin.

/dev/null on UNIX systems is a special file that you can write data to that can never be retrieved, and, if you read from it, you will all get back an End-Of-File condition.

You need to be more precise:

- Does "display files" mean file names and information on the file (such as owner or size), or file content?

- When you say "first two", what kind of ordering do you imply on the files, and what is the set of files to be considered?

- Why *at the same time*, and not *after they have been displayd*????
