createing directories and moving files into it

[Bee Tard]

I have an undetermined list of directories.

I am trying to loop through them all and in each one I want to make a
directory called 'images'. when i do this, I want o move all the imagges
in that folder into it.

so i have a tree like this:

some-dir
\_abc
- img00971273.jpg
- img21234235.jpg
- img12345623.jpg
\_123
- img99554361.jpg
- img21234235.jpg
- img53840534.jpg
\_xyz
- img00930443.jpg
- img12364235.jpg
- img09982623.jpg
\_890
- img00923871.jpg
- img21292835.jpg
- img08836823.jpg

I would like to create


some-dir
\_abc
\__images
- img00971273.jpg
- img21234235.jpg
- img12345623.jpg

And so on and so forth.

Hope this illustration makes sense. I have tried to create a loop and go
through each directory and use system() to 'mkdir images' and mv *.jpg
/images

no luck as yet. really starting to like some of Ruby's fileutils. just
wish i could get moving with some of these tasks

All help greatly appreciated. I'll buy you a beer at lunch.

Hi ---

you can create a directory, if it doesn't yet exist, using fileutils:

irb(main):001:0> require "fileutils"
=> true
irb(main):002:0> FileUtils.mkdir_p "temp5"
=> "temp5"

If you do it again, that doesn't matter.
For moving files, I like the rio gem:

http://rio.rubyforge.org/


require "rubygems"
require "rio"

Iterate over the .rb files in a directory and its subdirectories.

rio('adir').all.files('*.rb') { |entrio|

# do some checks on entrio.to_s to classify things

if /\.jpg$/.match(entrio.to_s)
p "it's an image
end

}

Do also check that you have writing permissions on the directory you want to write to.

Best regards,

Axel

I did it this way:

for I in *; do mkdir ${I}/myFolder; mv ${I}/* ${I}/myFolder; done

was wondering forever about a ruby way. thanks for the help.

Using Rio's rename-mode:

require 'rio'

# This will work if the only images under 'some-dir' are
# as stated in the problem

rio('some-dir').rename.all.files('*.jpg') do |ifile|
ifile.dirname = rio(ifile.dirname,'images').mkdir
end

# This is little more robust

rio('some-dir').dirs do |d|
d.rename.files('*.jpg') do |ifile|
ifile.dirname = rio(ifile.dirname,'images').mkdir
end
end
