File Handling

cool ...

Is there a way to RENAME a file [using RUBY] ?

[Nubeat7]

yes, just updated the list above..

Thanks for the LINK. Was having trouble finding the Ruby 1.9.3.

That's great. Now I just need to study Ruby to find out how to trigger subs with those code lines.

I know how to push strings in and out with "@" I/O, but not yet clear on how to trigger a Ruby sub on demand.

Ah... wait... I think I see. Just replace my modules with a Ruby module and those things will just run.

Great. Off to give it a go.

[S1User]

Oh man. I've been working way too hard not using Ruby modules. This below is much cleaner than the rats nest of primitives I had doing the same thing before.

You guys are great.

Back to an issue I'm having

It seems FS RUBY does not have the FileUtils class.

What I'm trying to do is:

1. Copy a file to a new dest folder ... then,

2. Re-name the new [copied] file.

3. Insuring that the original file remains intact at original location.

I've used the posted 'File.rename(@old_name, @new_name)' , but it is removing the original file

Note: The goal. I have to make copies of a single file and rename them as new files in a new folder. There could be a dozen or more copies]. I'm using a filename list to increment through in the rename process.

Note 2. I also tried the EXEC primitive to do the copy. I can't seem to get that to work.

I suck

Hi,

here a method 4U i got from DWB (hope he don't mind)

Code: Select all

def copy_file(src,dest)
    File.open(src, 'rb') do |s|
        File.open(dest, 'wb', s.stat.mode) do |f|
            IO.copy_stream(s, f)
        end
    end
end

Keep on Doing!
Walter

Thanks Walter [....and DWB]

I'll give this a go when I get back.

Appreciate.

[RJHollins]

hmmm ... no luck getting this code working ... as yet.
