You sure can. Here's an example:

object = "whatever"

# this code saves an object
File.open("path/to/file", "w") { |file| Marshal.dump(object, file) }

# this code loads the object back
object = File.open("path/to/file") { |file| Marshal.load(file) }

Hope that helps.

Hope that helps.

Just a small addition: I usually prefer to use mode "b" for marshal
files because they are binary, it helps documenting and it is more cross
platform.

Kind regards
