::mktmpdir creates a temporary directory.
The directory is created with 0700 permission.
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, ādā 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 ".../foo...bar" }
The directory is created under ::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..." }
If a block is given, it is yielded with the path of the directory. The directory and its contents are removed using FileUtils.remove_entry_secure before ::mktmpdir returns. The value of the block is returned.
Dir.mktmpdir {|dir| # use the directory... open("#{dir}/foo", "w") { ... } }
If a block is not given, The path of the directory is returned. In this case, ::mktmpdir doesn't remove the directory.
dir = Dir.mktmpdir begin # use the directory... open("#{dir}/foo", "w") { ... } ensure # remove the directory. FileUtils.remove_entry_secure dir end
