Remove directories
rmdir [-pv]
directory ...
The rmdir utility removes the directory entry specified by each directory argument, provided it is empty.
Arguments are processed in the order given. In order to remove both a parent directory and a subdirectory of that parent, the subdirectory must be specified first so the parent directory is empty when rmdir tries to remove it.
The following option is available:
-p
Each directory argument is treated as a pathname of which all components will be removed, if they are empty, starting with the last most component. (See rm(1) for fully non-discriminant recursive removal.)
-v
Be verbose, listing each directory as it is removed.
The rmdir utility exits with one of the following values:
0
Each directory referred to an empty directory and was removed successfully.
1
An error occurred while attempting to remove one or more directories.
2
Invalid arguments.
Remove the directory foobar, if it is empty:
$ rmdir foobar
Remove all directories up to and including cow, stopping at the first non-empty directory (if any):
$ rmdir -p cow/horse/monkey
