Yeah, I just tell our Linux newbies tar xf
, as in "extract file", and that seems to stick perfectly well.
Per https://www.gnu.org/software/tar/, it's been the case since 2004, so for about 19 and a half years...
German here and no shit - that is how I remember that since the first time someone made that comment
Not German but I remember the comment but not the right letters so I would have killed us all.
The Fish shell shows me just the past command with tar So I don't need to remember strange flags
I use zsh and love the fish autocomplete so I use this:
https://github.com/zsh-users/zsh-autosuggestions
Also have fzf
for ctrl + r
to fuzzy find previous commands.
I believe it comes with oh-my-zsh, just has to be enabled in plugins and itjustworks™
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.
Yeah that's a rather important point that's conveniently left out too often. I routinely extract individual files out of large archives. Pretty easy and quick with zip, painfully slow and inefficient with (most) tarballs.
A tar directory also preserves file permissions. And can preserve groups/ownership if needed.
Can you evaluate the directory tree of a tar without decompressing? Not sure if gzip/bzip2 preserve that.
Obligatory shilling for unar, I love that little fucker so much
unar <yourfile>
unzip
doesn'tVoicebanks 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.
When I was on windows I just used 7zip for everything. Multi core decompress is so much better than Microsoft's slow single core nonsense from the 90s.
There's several levels you can use to trade off additional space for requiring more processing power. That being said, I hate xz and it still feels slow AF every time I use it.
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?
Yeah, Facebook!
Sucks but yes that tool is damn awesome.
Meta also works with CentOS Stream at their Hyperscale variant.
Makes sense. There are actual programmers working at facebook. Programmers want good tools and functionality. They also just want to make good/cool/fun products. I mean, check out this interview with a programmer from pornhub. The poor dude still has to use jquery, but is passionate to make the best product they can, like everone in programming.
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.
I usually suppress output of either wget (-q) or of tar (no v flag), otherwise I think the output gets mangled and looks funny (you see both download progress and files being extracted).
Can someone explain why MacOS always seems to create _MACOSX folders in zips that we Linux/Windows users always delete anyway?
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.
You're thinking of the thumbs.db
files: https://en.wikipedia.org/wiki/Windows_thumbnail_cache#Thumbs.db
Huh, never noticed that. Probably always thought that was just part of the program/files needed.
this is a complete uneducated guess from a relatively tech-illiterate guy, but could it contain mac-specific information about weird non-essential stuff like folder backgrounds and item placement on the no-grid view?
They're Metadata specific for Macs.
If you download a third party compression tool they'll probably have an option somewhere to exclude these from the zips but the default tool doesn't Afaik.
Thanks! Hmm, never thought of looking at 7zip's settings to see if it can autodelete/not unpack that stuff. I'll see if I can find such a setting!
You can definitely check, but I would expect the option to exist when the archive is created rather than when it's extracted
Because Apple always gotta fuck with and "innovate" perfectly working shit
Windows's built-in tool can make zips without fucking with shit AND the resulting zip works just fine across systems.
Mac though...Mac produced zips always ALWAYS give me issues when trying to unzip on a non-mac (ESPECIALLY Linux)
HFS+ has a different features set than NTFS or ext4, Apple elect to store metadata that way.
I would imagine modern FS like ZFS or btrfs could benefit from doing something similar but nobody has chosen to implement something like that in that way.
I gotcha:
Windows File System
From what I know, no compression or COW
In my experience less stable than ext4/ZFS but maybe it's better nowadays.
Great summary, but I've to add that NTFS is WAY more stable than ext4 when it comes to hardware glitches and/or power failures. ZFS is obviously superior to both but overkill for most people, BTRFS should be a nice middle ground and now even NAS manufacturers like Synology are migrating ext4 into BTRFS.
Well that's good to know because I had some terrible luck with it about a decade ago. Although I don't think I would go back to windows, I just don't need it for work anymore and it's become far too complex.
I've also had pretty bad luck with BTRFS though, although it seems to have improved a lot in the past 3 years that I've been using it.
ZFS would be good but having to rebuild the kernel module is a pain in the ass because when it fails to build you're unbootable (on root). I also don't like how clones are dependant on parents, requires a lot of forethought when you're trying to create a reproducible build on eg Gentoo.
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.
I use .tar.gz in personal backups because it's built in, and because its the command I could get custom subdirectory exclusion to work on.
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:
