Create directory where specific files exist in ruby

Question

Using the following two lines I create the file "tmp.txt" in each directory where file_name exist. Than I open the file and write into it an array which I created before:

tmp_file = File.expand_path(File.dirname(file_name)) + "/temp.txt"
File.open(tmp_file, 'w') {|f| f.write array.join("\n")}

How can I create now also a empty directory into the same directories where tmp.txt is created?

I tried something like this:

File.expand_path(File.dirname(file_name)) + FileUtils.mkdir("/NewDirectory")

The first line doesn't create a new file, it only returns a path. — Stefan

Cannot be reproduced. I do not understand why you thought that a path ending with "temp.txt" would be related to creating a file named "tmp.txt". — sawa

@Stefan: I'm creating the tmp.txt and than write into it some strings (which comes from an array). Have edited the question now hopefully for better understanding. — JohnDoe

Create directory path and pass it to FileUtils.mkdir.

BTW, Instead of concatenate using +, use File::join instead:

dirpath = File.expand_path(File.join(File.dirname(file_name), 'NewDirectory'))
FileUtils.mkdir(dirpath)

Just pass a correct dirname to mkdir:

FileUtils.mkdir(File.expand_path(File.dirname(file_name)) + "/NewDirectory")
