Renaming a file inside a zip

Hello,

Can anyone help me or give me any clue on how to rename a file (or folder) inside a zip file without having to unzip it first. I'm trying to do this using the rubyzip gem without luck.

Thanks,

Elías

You must require 'zip/zipfilesystem' and

Zip::ZipFile.open('my.zip') do |zipfile|   zipfile.file.rename 'orignal_name.txt', 'new_name.txt' end

And this is it, for more information see the Zip::ZipFileSystem class documentation.

Hi Franco,

Thanks for your reply, but still it ain't working for. I need to rename a folder not a file. It works fine for file but not for folders. I tried this and it correctly renamed the file build.yml to builder.yml, BUT the folder wasn't rename, instead it created a new folder in the same level of the one I wanted to rename. Any clues?

    Zip::ZipFile.open('/home/elioncho/Desktop/MyApp.zip'){|zf|       parent_folder = zf.get_entry('Test/')       file = zf.get_entry('Prueba/build.yml')       parent_folder.name = 'Prueba/testing/'       file.name = 'Prueba/builder.yml'     }

I copied a wrong code, here it is. As I say before it only works for renaming the file not the folder.

    Zip::ZipFile.open('/home/elioncho/Desktop/MyApp.zip'){|zf|       parent_folder = zf.get_entry('Test/')       file = zf.get_entry('Test/build.yml')       parent_folder.name = 'Testing/'       file.name = 'Test/builder.yml'     }

There is no method to directly rename a directory, you must use the rename in every file between the directory like this:

Zip::ZipFile.open('my.zip') do |zipfile|   zipfile.file.rename 'original_dir/orignal_name.txt', 'new_dir/ original_name.txt' end

And after that you can remove the original directory.
