 The options parameter is a hash of options, taken from the list :force, :noop, :preserve, and :verbose. :noop means that no changes are made. The other three are obvious. Each method documents the options that it honours. All methods that have the concept of a “source” file or directory can take either one file or a list of files in that argument. See the method documentation for examples. There are some `low level' methods, which do not accept any option: Bundler8b7c:f320:99b9:690f:4595:cd17:293a:c069ileUtils.copy_entry(src, dest, preserve = false, dereference = false)

end  This method removes a file system entry path. path shall be a regular file, a directory, or something. If path is a directory, remove it recursively. This method is required to avoid TOCTTOU (time-of-check-to-time-of-use) local security vulnerability of rm_r. rm_r causes security hole when: 
 Parent directory is world writable (including /tmp). 
 Removing directory tree includes world writable directory. 
 The system has symbolic link. 
 To avoid this security hole, this method applies special preprocess. If path is a directory, this method chown(2) and chmod(2) all removing directories. This requires the current process is the owner of the removing whole directory tree, or is the super user (root). WARNING: You must ensure that ALL parent directories cannot be moved by other untrusted users. For example, parent directories should not be owned by untrusted users, and should not be world writable except when the sticky bit set. WARNING: Only the owner of the removing directory tree, or Unix super user (root) should invoke this method. Otherwise this method does not work. For details of this security vulnerability, see Perl's case:

end  This method removes a file system entry path. path shall be a regular file, a directory, or something. If path is a directory, remove it recursively. This method is required to avoid TOCTTOU (time-of-check-to-time-of-use) local security vulnerability of rm_r. rm_r causes security hole when: 
 Parent directory is world writable (including /tmp). 
 Removing directory tree includes world writable directory. 
 The system has symbolic link. 
 To avoid this security hole, this method applies special preprocess. If path is a directory, this method chown(2) and chmod(2) all removing directories. This requires the current process is the owner of the removing whole directory tree, or is the super user (root). WARNING: You must ensure that ALL parent directories cannot be moved by other untrusted users. For example, parent directories should not be owned by untrusted users, and should not be world writable except when the sticky bit set. WARNING: Only the owner of the removing directory tree, or Unix super user (root) should invoke this method. Otherwise this method does not work.
