By using rm –[options] <file name> command,you can erase any file you have selected.
Sample options ;
-e : Gives out information after the deletion of the file.
-f : Deletes write protected files without asking for confirmation.(This option has no returning point, and should not be used unless required.)
-I : Asks for confirmation before deleting the file.
-r : Continuously deletes sub-directories without asking for confirmation.

command, you can delete every file whose name begins with ‘’Bilgi-Islem’’.
$ rm -rf deneme
command, you can delete the file named ‘’deneme’’ and its every sub-directory without any confirmation.
