Returns true if the named file is a directory, or a symlink that points at a directory, and false otherwise.
file_name can be an IO object.
File.directory?(".")
Returns true if new is newer than all old_list. Non-existent files are older than any file.
FileUtils.uptodate?('hello.o', %w(hello.c hello.h)) or \ system 'make hello.o'

Updates modification time (mtime) and access time (atime) of file(s) in list. Files are created if they don’t exist.
FileUtils.touch 'timestamp' FileUtils.touch Dir.glob('*.c'); system 'make'

Returns the result of converting the serialized data in source into a Ruby object (possibly with associated subordinate objects). source may be either an instance of IO or an object that responds to to_str. If proc is specified, each object will be passed to the proc, as the object is being deserialized.
Never pass untrusted data (including user supplied input) to this method. Please see the overview for further details.
Indicates whether this DH instance has a private key associated with it or not. The private key may be retrieved with DH#priv_key.
Indicates whether this DSA instance has a private key associated with it or not. The private key may be retrieved with DSA#private_key.
Returns the EC::Group that the key is associated with. Modifying the returned group does not affect key.
Sets the EC::Group for the key. The group structure is internally copied so modification to group after assigning to a key has no effect on the key.
Returns whether this EC instance has a private key. The private key (BN) can be retrieved with EC#private_key.
Does this keypair contain a private key?
Returns the root node. A Document may only have one root node: yaml.org/spec/1.1/#id898031
