    Obligatory shilling for unar, I love that little fucker so much

    • Single command to handle uncompressing nearly all formats.
    • No obscure flags to remember, just unar <yourfile>
    • Makes sure output is always contained in a directory
    • Correctly handles weird japanese zip files with SHIFT-JIS filename encoding, even when standard unzip doesn’t

        Voicebanks for Utau (free (as in beer, iirc) clone of Vocaloid) are primarily distributed as SHIFT-JIS encoded zips. For example, try downloading Yufu Sekka’s voicebank: http://sekkayufu.web.fc2.com/ . If I try to unzip the “full set” zip, it produces a folder called РсЙ╠ГЖГtТPУ╞Й╣ГtГЛГZГbГgБi111025Бj. But unar detects the encoding and properly extracts it as 雪歌ユフ単独音フルセット(111025). I’m sure there’s some flag you can pass to unzip to specify the encoding, but I like having unar handle it for me automatically.

          Ah, that’s pretty cool. I’m not sure I know of that program. I do know a little vocaloid though, but I only really listen to 稲葉曇(Inabakumori).

            I know inabakumori! Their music is so cool! When I first listened to rainy boots and lagtrain, it made me feel emotions I thought I had forgotten a long time ago… I wish my japanese was good enough to understand the lyrics without looking them up ._. I’m also a huge fan of Kikuo. His music is just something completely unique, not to mention his insane tuning. He makes Miku sing in ways I didn’t think were possible lol

              I get you, I want to learn more Japanese. I only understand a very small amount at this point. I don’t have any Miku songs that I have really wanted to listen to, but that could change. I might check out Kikuo then. Also I love the animations Inabakumori release with their songs too. They have some new stuff that’s really good if you haven’t checked it out yet.

      You can’t decrease something by more than 100% without going negative. I’m assuming this doesn’t actually decompress files before you tell it to.

      Does this actually decompress in 1/13th the time?

          That’s not Linux doing that. It’s the demons in your hardware trying to escape. They normally don’t cause too many issues luckily, but if you don’t close the portals occasionally they can take over your system.

        Yeah, those tend to be pre-folder settings for the File Explorer.
        Like View options, thumbnails and such.

        It’s been a while for me, but I think there was something specially for thumbnails too. You might find one if you go into the folder options and set a folder to optimized for pictures/videos and add some to it.

          I think it’s a joke about how people from Poland have a lot of consonant letters in their name, particularly the letter Z. This appears strange to non-poles, and thus became the subject of many jokes. So ZSTD looks a little bit like a Polish name in the sense that it’s made up of many consonant letters, including a Z.

          More examples of people making fun of Polish names:

    When I’m feeling cool and downloading a *.tar* file, I’ll wget to stdout, and tar from stdin. Archive gets extracted on the fly.

    I have (successfully!) written an .iso to CD this way, too (pipe wget to cdrecord). Fun stuff.

            TAr stands for Tape Archive. Tapes store data sequentially. Downloads are done sequentially.

            It’s really just like a far away tape drive.

    I’m the weird one in the room. I’ve been using 7z for the last 10-15 years and now .tar.zst, after finding out that ZStandard achieves higher compression than 7-Zip, even with 7-Zip in “best” mode, LZMA version 1, huge dictionary sizes and whatnot.

    zstd --ultra -M99000 -22 files.tar -o files.tar.zst

      You can actually use Zstandard as your codec for 7z to get the benefits of better compression and a modern archive format! Downside is it’s not a default codec so when someone else tries to open it they may be confused by it not working.

        That is an interesting implementation of security through obscurity…

        How does one enable this on the standard 7Zip client?

          On Windows, it’s easy! Unfortunately, on Linux, as far as I know, you currently have to use a non-standard client.

    Zip makes different tradeoffs. Its compression is basically the same as gz, but you wouldn’t know it from the file sizes.

    Tar archives everything together, then compresses. The advantage is that there are more patterns available across all the files, so it can be compressed a lot more.

    Zip compresses individual files, then archives. The individual files aren’t going to be compressed as much because they aren’t handling patterns between files. The advantages are that an error early in the file won’t propagate to all the other files after it, and you can read a file in the middle without decompressing everything before it.

      Nowhere in here do you cover bzip, the subject of this meme. And tar does not compress.
