Ruby eval file content

Permissions are copied regardless preserve. Copies file contents of src to dest. Copies stream src to dest. Copies a file content src to dest. Copies src to dest. If src is a directory, this method copies all its contents recursively. If src is not same as dest , copies it and changes the permission mode to mode.

This method removes destination before copy. In the first form, creates a hard link link which points to target. But if the :force option is set, overwrites link. In the third form, creates several hard links in the directory dir , pointing to each item in targets. In the first form, creates a symbolic link link which points to target. In the third form, creates several symbolic links in the directory dir , pointing to each item in targets.

Moves file s src to dest. If file and dest exist on the different disk partition, the file is copied then the original file is removed. Removes a directory dir and its contents recursively. This method ignores StandardError if force is true. This method removes a file system entry path. If path is a directory, remove it recursively. To avoid this security hole, this method applies special preprocess. Find centralized, trusted content and collaborate around the technologies you use most.

Connect and share knowledge within a single location that is structured and easy to search. Also is it there a way to make sure that this file is unreadable so that passwords could be stored in this file? Note: per file security is going to be addressed by where the file is located and your operating system, and server software. Ruby has the ENV constant that acts like a Hash and holds the environment of the shell you are using.

As an example, there is a file called environment. It has instructions and holds the template that users can modify freely, with instructions to copy the file to environment. The sample file looks like this:. This loads the file and uses the ENV that is a globally scoped constant for the application. The sensitive file should also be listed in the repository's ignore mechanism. It should never be made public. And, unless you have a very, very specific need, don't use it in production code.

As for making the file inaccessible, that is an operating system level problem that can't be solved without information on the environment, OS, setup, etc.

The purpose of a local variable is to be used temporally within a method definition or a block. Using it outside of such environments, particularly across files defeats the purpose of it. You should not need to do it, and Ruby does not have a simple way to do it.

If you are using variables correctly, and want to share variables between files, that should be other types of variables such as instance, class, or global variables. Or, for the purpose of setting environments, you should be using constants. He is a early adopter who is consistantly looking for new exciting technologies.

The difference is that in IRB everything is being eval'd, so it's all in the same scope. That is, you're essentially doing this in IRB:. Because you're defining a method or variable named machine in IRB but not in your Ruby script. How are we doing? Please help us improve Stack Overflow.
