Oblig. XKCD:
tar -hEdit: wtf… It’s actually
tar -?. I’m so disappointedboom
tar -xzf
(read with German accent:) extract the files
tar eXtactZheVeckingFile
You don’t need the v, it just means verbose and lists the extracted files.
You don’t need the z, it auto detects the compression
That’s still kinda new. It didn’t always do that.
Per https://www.gnu.org/software/tar/, it’s been the case since 2004, so for about 19 and a half years…
Telling someone that they are Old with saying they are old…
Something something don’t cite the old magics something something I was there when it was written…
That’s yet another great joke that GNU ruined.
Where .7z at

cool people use zst
.tar.xz
xz is quite slow though
tar c file | pxz > file.tar.xz
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.
It starting 0.5 seconds slower than usual saved us all a bit of a headache as it turns out.
Same algo as in 7z
Yeah, it’s similar enough to tar.gz to always confuse me.
wait until you learn about
.tar.lzGood for image backups, after zeroing empty space.
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
unzipdoesn’t
gonna start lovingly referring to good software tools as “little fuckers”
Happy cake day!
What weird Japanese zip files are you handling?
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
unzipthe “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 tounzipto specify the encoding, but I like havingunarhandle it for me automatically.
Where’s .7z people?
ZSTD FTW
Damn you guys borrowing consonants from polish names now?
Wut?
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’llwgetto stdout, and tar from stdin. Archive gets extracted on the fly.I have (successfully!) written an
.isoto CD this way, too (pipe wget to cdrecord). Fun stuff.Something like
wget avc.com | tar xvf?Almost, I think.
wget -O - http://example.com/archive.tar | tar -xvf -Didnt think this would ever work
TAr stands for Tape Archive. Tapes store data sequentially. Downloads are done sequentially.
It’s really just like a far away tape drive.
Can someone explain why MacOS always seems to create _MACOSX folders in zips that we Linux/Windows users always delete anyway?
Window adds desktop.ini randomly too
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.
Linux adds .demon_portal files all over my computer too.
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.

That’s a big drive.
I mean xz/7z has kind of been the way for at least a decade now
Well, tar.zstd is starting to be the thing now.
First bundling everything in a tar file just to compress the thing in an individual step is kinda stupid, though. Everything takes much longer because of that. If you don’t need to preserve POSIX permissions, tar is pointless anyway.
Slower, yes. More compression, yes. Stupid, no. tar serves a purpose beyond persevering permissions.
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.
