    That's not a relevant response to Argel's suggestion; or, it's not relevant based on anything you've told us about your requirements.

    Sure, you'll find many nodes here with which urge use of Perl's own capabilities or modules to achieve a goal, but that's NOT the same as deprecating use of an outside capability... nor somehow is it somehow 'non-"programatically".'

    edit: s/with/which/

      I want to extract one file perform some operation and then extract the next which is not possible by 7zip as it would extract the full content of rar file in one go

        Unless there is some dependancy you haven't disclosed -- say, for example, that the content of the file currently being processed determines which file to extract and process next -- your desire to extract them one at a time is not a war-stopper; it is merely one alternative approach:
        Pseudocode: un7zip ($archive); @todo = readdir (extracted files); for $todo(@todo) { process as you wish... }
        Most decompression/compression programs support extracting/adding individual files from/to an archive. This should work, but I only tested it against a .7z file. But I am not aware of any reason why it would not work with .rar files.
        7z.exe e <archive_name.rar> <path_to_file_in_archive>
        Here's an example. Given a 7-zip file called test.7z, containing:
        test test/foo test/bar
        This should extract just 'bar' to your current working directory:
        7z.exe e test.7z test/bar
