Instance Method Details

#run(input_file, output_file) ⇒ void

This method returns an undefined value.

Execute the decompress command.

Archives (.zip/.7z/.tar/...) extract into the output directory; single-file streams decompress to the output file.

Parameters:

  • input_file (String) —

    Path to input file

  • output_file (String) —

    Path to output file or directory
