will first remove baz/, then bar/ and finally foo/ thus removing the entire directory tree specified in the command argument. rmdir will not remove a directory if it is not empty in UNIX. The rm command will remove a directory and all its contents recursively. For example:
If pushd is not provided with a path argument, it changes instead to the next directory from the top of the stack, [clarification needed] which can be used to toggle between two directories. The popd command removes (or 'pops', in the stack analogy) the current path entry from the stack and returns to the path at the top of the stack as the new ...
srm (or Secure Remove) is a command line utility for Unix-like computer systems for secure file deletion. srm removes each specified file by overwriting, renaming, and truncating it before unlinking. This prevents other people from undeleting or recovering any information about the file from the command line.
The list handle should then be a pointer to the last data node, before the sentinel, if the list is not empty; or to the sentinel itself, if the list is empty. The same trick can be used to simplify the handling of a doubly linked linear list, by turning it into a circular doubly linked list with a single sentinel node.

Deletes a directory along with all of the files and subdirectories that it contains. Normally, it will ask for confirmation of the potentially dangerous action. Since the RD (RMDIR) command can not delete a directory if the directory is not empty (except in Windows NT & 10), the DELTREE command can be used to delete the whole directory.
Under Windows Explorer, the content of a directory can also be hidden just by appending a pre-defined CLSID [12] to the end of the folder name. The directory is still visible, but its content becomes one of the Windows Special Folders. [13] However, the real content of this directory can still be seen using the CLI command dir.
In some cases, zero-byte files may be used to convey information like file metadata (for example, its filename may contain an instruction to a user viewing a directory listing such as documents-have-been-moved-to-partition-D, etc.); or to put in a directory to ensure that it is non-empty, since some tools such as backup and revision control ...
