Creating an empty file in Ruby: “touch” equivalent?

Question

What is the best way to create an empty file in Ruby?

Something similar to the Unix command, touch:

touch file.txt

Answer 1

If you are worried about file handles:

File.open("foo.txt", "w") {}

From the docs:

If the optional code block is given, it will be passed the opened file as an argument, and the File object will automatically be closed when the block terminates.
