Method: FileUtils.makedirs

Defined in:
lib/fileutils.rb

.makedirs ⇒ Object

Creates directories at the paths in the given list (a single path or an array of paths), also creating ancestor directories as needed; returns list if it is an array, [list] otherwise.

Argument list or its elements should be interpretable as paths.

With no keyword arguments, creates a directory at each path in list, along with any needed ancestor directories, by calling: Dir.mkdir(path, mode); see Dir.mkdir:

FileUtils.mkdir_p(%w[tmp0/tmp1 tmp2/tmp3]) # => ["tmp0/tmp1", "tmp2/tmp3"]
FileUtils.mkdir_p('tmp4/tmp5')             # => ["tmp4/tmp5"]

Keyword arguments:

  • mode: mode - also calls File.chmod(mode, path); see File.chmod.

  • noop: true - does not create directories.

  • verbose: true - prints an equivalent command:

    FileUtils.mkdir_p(%w[tmp0 tmp1], verbose: true)
FileUtils.mkdir_p(%w[tmp2 tmp3], mode: 0700, verbose: true)

    Output:

    mkdir -p tmp0 tmp1
mkdir -p -m 700 tmp2 tmp3

Raises an exception if for any reason a directory cannot be created.

FileUtils.mkpath and FileUtils.makedirs are aliases for FileUtils.mkdir_p.
