How to copy the directory files only to another directory?

Ruby
1

Hi,

Consider the below file system:

                       C:\
                       |
    --------------------------------------------------
    |                  |                |            |
 Test1               Test2            Test3        Test4
   |                   |                |            |

------------ c.txt e.docx -------------
| | | |
a.pdf b.pdf m.txt aa.pdf

Now I want to copy only regular files from the “C:” to “D:\document”.

Can anyone help me here for the same?

You shouldn’t be doing anything in “C:”.
Define “regular files”?

I just want to copy only - a.pdf,b.pdf,c.txt,e.docx, m.txt,aa.pdf files
to the folder “D:\document”,not with their directories.

There are a few ways to do this, this one seems to work:

Dir.chdir ‘C:/’
files = Dir.glob(’/*.pdf’) +
Dir.glob(’/.txt’) +
Dir.glob(’**/.docx’)
files.each do |fname|
File.rename File.absolute_path(fname), ‘D:/document/’ +
File.basename(fname)
end

The example I gave you only copies the files, not the directories. You
may get name conflicts as a result, however.
Also the example I gave will go through every directory. If you want to
limit this you’ll need to be more specific in your code.

For all files, just use Dir.glob(’**/*’)

Nice idea! But as an example i used such .txt,.pdf extensions. But there
can be various types of files, all I have to copy. But not any folder or
directories.

Yes,that I understood,but What I am trying to say is in my case the file
extension can be any thing, like .vbs,.vb,rb,xlsx etc - anything. So
without hard-coding anyway to get any type of file names excluding their
directories?

As above,
Dir.glob(’**/*’)

See my code:

C:>irb
irb(main):001:0> Dir.pwd
=> “C:/”
<‘C:/Documents and Settings/rakshiar/My Documents/userdata/Ruby’)
=> 0
irb(main):003:0> Dir.pwd
=> “C:/Documents and Settings/rakshiar/My Documents/userdata/Ruby”
irb(main):004:0> Dir.glob(’**/*’)
=> [“Books”, “Books/Beginning Ruby.pdf”, “Books/Russ Olsen Eloquent
Ruby.pdf”, "
Books/Test.txt", “Books/testfile”, “Scripts”, “Scripts/downloadv3.rb”,
“Scripts/
FileNamerenaming.rb”]
irb(main):005:0>

Here I am also getting “Books”,“Scripts” - which are folder,but I don’t
want to copy them,rather their contents.

Ok, try **/.

Perfect! Thanks for your help.

C:>irb
irb(main):001:0> Dir.chdir(‘C:/Documents and Settings/rakshiar/My
Documents/us>
=> 0
irb(main):002:0> Dir.pwd
=> “C:/Documents and Settings/rakshiar/My Documents/userdata/Ruby”
irb(main):003:0> Dir.glob(’**/.’)
=> [“Books/Beginning Ruby.pdf”, “Books/Russ Olsen Eloquent Ruby.pdf”,
“Books/Tes
t.txt”, “Scripts/downloadv3.rb”, “Scripts/FileNamerenaming.rb”]
irb(main):004:0>

The above code during renaming deleting the file also from here
“File.absolute_path(fname)”.

Anyway to retain those files there?

Thanks

When you rename something, you are moving it – if you wish to retain
those files in their original place, you need to copy them to the new
destination, not rename them.

Oops, I didn’t read your request carefully enough the first time.

Here’s a copy version:

require ‘fileutils’
Dir.chdir ‘C:/’
files = Dir.glob(’**/.)
files.each do |fname|
FileUtils.copy File.absolute_path(fname), ‘D:/document/’ +
File.basename(fname)
end

I think you may need/want to test for file-ness (and not directory- or
other-ness) of the files as well.

Personally, I’d go with the Find stdlib:

require ‘find’

def find_files(start,&blk)
Find.find(start) do |path|
if File.file?(path)
yield path
end
end
end

def gather_files(src,dst)
raise “#{src} is not a directory” unless File.directory?(src)
raise “#{dst} is not a directory” unless File.directory?(dst)
find_files(src) {|s| File.rename(s,File.join(dst,File.basename(s)))}
end

Then call gather_files with your source directory and target
directory; in your example:

gather_files("C:",“D:\document”)

should do it.

No problem, I learned some new stuff writing that.

But… and I cannot stress this enough… DO NOT run that on your root
drive!
