zip2zstd

This is a quick and dirty tool for converting a zip file to a zstd-compressed tar file without the intermediate i/o touching the disk

Usage

To use the tool, run it with the following arguments

zip2zstd <input zip> <output tar.zst>

The tool doesn't print any information unless there was an error

Example

% unzip -ql ESStatistikListeModtag-20201018-173254.zip
