The standard File module has the usual file tests available:
RUBY_VERSION # => "1.9.2"
bashrc = ENV['HOME'] + '/.bashrc'
File.exist?(bashrc) # => true
File.file?(bashrc) # => true
File.directory?(bashrc) # => false
You should be able to find what you want there.
OP: “Thanks but I need all three true or false”
Obviously not. Ok, try something like:
def file_dir_or_symlink_exists?(path_to_file)
File.exist?(path_to_file) || File.symlink?(path_to_file)
end
file_dir_or_symlink_exists?(bashrc) # => true
file_dir_or_symlink_exists?('/Users') # => true
file_dir_or_symlink_exists?('/usr/bin/ruby') # => true
file_dir_or_symlink_exists?('some/bogus/path/to/a/black/hole') # => false
