Add this line to your application's Gemfile:

gem 'tmpdir'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install tmpdir


Dir.mktmpdir creates a temporary directory. The directory is created with 0700 permission.

Application should not change the permission to make the temporary directory accessible from other users.

The prefix and suffix of the name of the directory is specified by the optional first argument, prefix_suffix.

  • If it is not specified or nil, "d" is used as the prefix and no suffix is used.
  • If it is a string, it is used as the prefix and no suffix is used.
  • If it is an array, first element is used as the prefix and second element is used as a suffix.
Dir.mktmpdir {|dir| dir is ".../d..." }
Dir.mktmpdir("foo") {|dir| dir is ".../foo..." }
Dir.mktmpdir(["foo", "bar"]) {|dir| dir is ".../" }

The directory is created under Dir.tmpdir or the optional second argument tmpdir if non-nil value is given.

Dir.mktmpdir {|dir| dir is "#{Dir.tmpdir}/d..." }
Dir.mktmpdir(nil, "/var/tmp") {|dir| dir is "/var/tmp/d..." }
