I found a couple of different ways to move a file with ROR, but I couldnt get it to work, whats the best and simplest way to move or rename a file ?
You can use the standard method:
File.rename(old_name, new_name)
Or you can use FileUtils which offers additional functionality.

I am wondering if it is possible to accomplish the following, given some context and example.
I have files in "Server\Share\Folder\File##.ext"
Sometimes the "File##.ext" can be "File01.ext" through "File20.ext", and other times it may be "File01.ext" through "File40.ext"
Sometimes there are less of these files, sometimes there are more.
I want a batch file to take the files from "Server\Share\Folder\File##.ext" and move them to "Server\Share\OtherFolder\File##.ext". I know I can accomplish this easily with:
copy /y "Server\Share\Folder\File01.ext" "Server\Share\OtherFolder\File01.ext"
Then just add another line for each extra "File02.ext, File03.ext, etc., but I am wondering if it is possible to make it so that any file that resembles "File##.ext" can be included, so that no matter how many ## I have, it always works without issue.
Thanks in advance for any and all advice!
EDIT
Someone mentioned using Wildcards, but my question with that is - lets say those files are File01.ext through File05.ext, will it match what it finds to the newly moved file? Like will it find File01 from File?? on the source and Make it File01 from File?? at the destination?
You can accomplish this task with a FORloop program in batch-file.
You can also loop through the Commands using : and variable name.
Combining these two would help you get what you want.

Instead of putting all the i18n resources into a single message file, I want to divide them into several files. Anybody can kindly tell me how can I do that? because the documentation of Play doesn't give me any idea.
Use the Messages Module, really nice for this purpose.
You can't on Play. Anyway, why would you need to do that? Makes harder to find where the keys for I18N are. If it's for "visual" purposes, just use comments (##) to create sections in the file.
I have a simple FileCreator Ruby class that has 1 method create which creates a blank txt file on my desktop. Using RSpec, how would I test this create method to make sure
that the file was created, without having to create the file? Would I use RSpec::Mocks? Can someone please point me in the right directory? Thanks!
After calling file_creator.create(100) you could search the folder for all File*.txt files and make sure the count matches. (Make sure to have your spec remove the test files after completion).
Dir.glob(File.join(File.expand_path("~/Desktop"), "File*.txt")).length.should == 100
Using Mocks: You could do something like this to verify that the File.open method is actually being called (to test that the files actually get created, though, you may want to consider actually creating the files like the first half of my answer).
File.should_receive(:open).exactly(100).times
You could also try using something like FakeFS which mocks the actual file system.
The simplest way to do it is as below:
FileCreator.count.should eq 100
Using Mechanize with Ruby I get a certain file using agent.get('http://example.com/foo.torrent'), with FileUtils or otherwise, how do I save this file to my hard drive (for instance, in a directory wherefrom the script is running)?
P.S. class => WWW::Mechanize::File
Well, WWW::Mechanize::File has a save_as instance method, so I suppose something like this might work:
agent.get('http://example.com/foo.torrent').save_as 'a_file_name'
Please note that the Mechanize::File class is not the most appropriate for large files. In those cases, one should use the Mechanize::Download class instead, as it downloads the content in small chunks to disk. The file will be downloaded to where the script is running (although you can specify a different path as well). You need to set the default parser first, create a new one or modify an existing parser. Then, save it to the desired path:
agent.pluggable_parser.default = Mechanize::Download
agent.get( "http://example.com/foo.torrent}").save("path/to/a_file_name")

Is there any way to make the "image" module store files under a new name on upload? Basically, someone could upload a file that says something like "macs are cool" or something equally absurd. Now, I don't want people to see that. I'd much rather have all the files renamed on upload to something like: "111494949478383.jpg". How would I go about accomplishing this?
The FileField Paths module should do what you want. It works with both core Upload, as well as the FileField and Imagefield modules. You may also want to check out Imagefield Tokens, which allows the use of node tokens in things like the default alt text for images.
You can use the module "filefield Paths", and put in the filename [raw] that way the uploaded picture will have the node's timestamp creation time.
Also you can use [raw]_[filename].[file-extension] or whatever combination you can use, take a look at "file name replacement patterns"
with hook_nodeapi you could move the files and rename the images when the node is saved.
Or you could add something to the image upload callback with hook form alter to rename the image once it has been uploaded
yep, form_alter is the way to go for this
there are file modules that basically use tokens to do this
edit also imagefield supports tokens http://drupal.org/node/152640
immagefield could be better in long run if cck going to Drupal 7
hope that helps
