One Linux command per day (6): rmdir command

Http://www.cnblogs.com/peida/archive/2012/10/27/2742076.html

Learn about Linux commands today: the RmDir command. RmDir is a commonly used command, the function of which is to delete an empty directory before a directory is deleted must be empty. (Note that the Rm-r dir command can be used instead of rmdir, but there is a lot of danger.) You must also have write access to the parent directory when you delete a directory.

1. Command format:

rmdir [Options] ... Directory...

2. Command function:

This command removes one or more subdirectory entries from a directory and must also have write access to the parent directory when a directory is deleted.

3. Command parameters:

-p recursively deletes the directory dirname, which is also deleted when its parent directory is empty after the subdirectory is deleted. If the entire path is deleted or a partial path is reserved for some reason, the system displays the appropriate information on the standard output.

-V,--verbose show instruction execution process

4. Command instance:
