I made a small utility for listing the file names inside an archive file, e.g. tar, zip, etc. This comes in handy when you download some software package using the command line but you aren’t sure whether to extract it in its own folder because you don’t know what the file structure inside is.
It only parses as little data as possible to get just file names, on some files like ZIPs it’ll be just the header but on others like tar it’ll have to walk through and seek to the start of each file. It should be pretty fast even on big files though
