Returns the real (absolute) pathname of pathname in the actual filesystem. The real pathname doesn’t contain symlinks or useless dots.
If dir_string is given, it is used as a base directory for interpreting relative pathname instead of the current directory.
The last component of the real pathname can be nonexistent.
Returns all components of the filename given in file_name except the last one (after first stripping trailing separators). The filename can be formed using both File::SEPARATOR and File::ALT_SEPARATOR as the separator when File::ALT_SEPARATOR is not nil.
File.dirname("/home/gumby/work/ruby.rb") #=> "/home/gumby/work"
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 the real (absolute) pathname of self in the actual filesystem.
Does not contain symlinks or useless dots, .. and ..
The last component of the real pathname can be nonexistent.
Returns system configuration directory.
This is typically “/etc”, but is modified by the prefix used when Ruby was compiled. For example, if Ruby is built and installed in /usr/local, returns “/usr/local/etc” on other platforms than Windows. On Windows, this always returns the directory provided by the system.
Returns system temporary directory; typically “/tmp”.
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?(".")
Creates one or more directories.
FileUtils.mkdir 'test' FileUtils.mkdir %w(tmp data) FileUtils.mkdir 'notexist', noop: true # Does not really create. FileUtils.mkdir 'tmp', mode: 0700
Creates one or more directories.
FileUtils.mkdir 'test' FileUtils.mkdir %w(tmp data) FileUtils.mkdir 'notexist', noop: true # Does not really create. FileUtils.mkdir 'tmp', mode: 0700
Creates a directory and all its parent directories. For example,
FileUtils.mkdir_p '/usr/local/lib/ruby'
causes to make following directories, if they do not exist.
/usr
/usr/local
/usr/local/lib
/usr/local/lib/ruby
You can pass several directories at a time in a list.
