tar --version

WhoLooksHere ,

Or is it -v

tiredofsametab ,

Depends. Short options are probably safer if the particular version and flavor of tar are unknown.

0x4E4F ,
@0x4E4F@sh.itjust.works avatar

So you either het version or verbose…slick AF 😏.

saigot ,

-v is verbose

I hitched my horse to just what I consider the basics–zip and unzip–and that has made it easy for me. But I’ve been stuck on those.

Extract anything:


<span style="color:#323232;">tar xf <archive_file>
</span>

Create a tbz2 archive:


<span style="color:#323232;">tar cjf <archive_file.tbz2> <stuff to put in it>
</span>

(And tossing in a -v is pretty universal, if that’s your thing.)

Some day, instead of commenting on a reddit Lemmy post, I think I’ll Google how to tell it to use .xz.

Ok, you know what? Today is finally that day. It’s just capital -J instead of lower-case -j! That’s easy enough to remember, I guess.

partial_accumen ,

Stay by the phone always. We may need you to defuse a bomb someday.

governorkeagan ,

Never thought I’d learn how to use tar on a meme post.

0x4E4F ,
@0x4E4F@sh.itjust.works avatar

Memes are one of the best source for Linux info 👍.

boredsquirrel ,

I guess man tar is cheating, but it is a command involving tar. Not a command using tar, but a tar command…

neoman4426 ,

I suppose tar --help would technically be a valid invoking of the binary itself if man tar doesn't

Emma_Gold_Man ,

But it would not work on older non-GNU versions of tar.

GNU introduced the “–foo” style long options, and it was a long time before Unix versions began adopting them.

bradorsomething ,

It didn’t say you could only enter one try, just that you had 10 seconds. The man page should give you something

boredsquirrel ,

True. But then I would use curl cheat.sh/tar

m4 ,

I just can recall tar xvzf but can't even remember what it's supposed to do.

Hawke ,

eXtract, Verbose, gZip, File.

Not sure why it doesn’t need the dash though.

r4venw ,
@r4venw@kbin.social avatar

I always learnt it as Xtract Zee File and to make a tar ball, you want to Compress Zee File

d00phy ,

The dash used to be how to could tell how long someone had been using tar. If they started with Linux, they probably use a dash. If they started on a UNIX variant, they probably don’t. Either way, the dash isn’t needed.

Also recently learned that recent versions of tar will autodetect compression. So for extraction, you just need “tar xf “

Hawke ,

Sacrilege.

best_username_ever ,

tar doesn’t need dashes because it’s weird.

tar cJf file.tar.xz /path/to/file

tar xJf file.tar.xz /path/to/file.tar.xz -C /path/to/untar

is not very hard to remember

LainTrain OP ,

Unless you use it daily, I think that’s something I’d struggle with memorising, I’d just alias it tbh along with ls options

prettybunnys ,

tar -czvf tar_name.tar.gz ./

rockSlayer ,

Yep, have this one committed to memory. Though if it asked me to uncompress a tarball, then I’d be fucked

thejml , (edited )

tar xzvf this_awesome_file.tgz

… fixed. Apparently I can’t type.

hallettj ,
@hallettj@leminal.space avatar

I think you want to remove the c because that means “create” an archive, and you’re missing a z which applies gzip decompression/compression

_thebrain_ ,

I suppose it is tar version dependent, but on any recent Linux version I have used, you can just tar xvf <tar_name.tar.{z,gz,xz,etc}> and it will automatically figure out if it is compressed, what tools were used to compress it, and how to decompress it.

But you are right, x and c are mutually exclusive.

thejml ,

Yeap, apparently I can’t type. So, we’d all be dead anyway with that bomb.

gravitas_deficiency ,

QED 🫠

Aurenkin ,

File not found, now we are dead.

prettybunnys ,

Sounds like an error message from a valid tar command

v_krishna ,
@v_krishna@lemmy.ml avatar

I even read this aloud in my head as “CREATE ZE VUCKING FILE” in a particularly bad German accent same as over 20 years ago when a friend I worked for drilled it in my head.

RealPuyo ,

Read it in tf2 medics voice

Edgarallenpwn ,
@Edgarallenpwn@midwest.social avatar

I didn’t realize that was my default German voice in my head. Thx

gravitas_deficiency ,

lol that’s honestly a great mnemonic

Anyone else make an untar.sh?

tar, the tape archiver, I used it with tape, early 90s

@b3an@lemmy.world avatar

Somehow, idk why. This one is stuck in my head:


<span style="color:#323232;">tar -zxvf filename.tar.gz
</span>
far_university1990 ,

tar xzvf

eXtract Ze Vucking File

Bread ,

I have to do this command often at work and I can never remember the letters perfectly. This is actually useful, thanks!

9point6 ,

Same, never used a mnemonic for it or anything, just

zxvf

Like it’s any other word

MonkderDritte , (edited )

z=zip (default in most tar), x=eXtract, v=verbose (not needed in most cases), f=target

prettybunnys ,

verbose … not needed?

If the words don’t happen how can I trust computer magic?

InFerNo ,

Yeah, how do I know that the PC isn’t slacking?

Slotos ,

Monitor the room temperature.

BestBouclettes ,

The bomb runs AIX. I’m sorry, you’re dead

MonkderDritte ,

tar zxvf filename.tar.gz file?

BestBouclettes ,

Nope, tar doesn’t handle compression on AIX. So it would be something like gzip -cd filename.tar.gz | tar xvf -

MonkderDritte ,

Ugh.

linearchaos ,
@linearchaos@lemmy.world avatar

I’ve never had a problem remembering tar, but properly using PV, somehow I’m just not able to store that information in my brain.

xkforce ,

Do people not use tab complete?

Voroxpete ,

Found the person who’s never used tar :-P

xkforce ,
  1. Thats not true and
  2. I am fully aware that there are 127 flags. That just makes this even sillier because you have so many valid options to disarm the bomb.
Zos_Kia ,
@Zos_Kia@lemmynsfw.com avatar

There’s an easy mnemonic for that : Compress Ze Vucking File !

synapse1278 ,
@synapse1278@lemmy.world avatar

Always think about tar commands in your best German accent !

JackGreenEarth , 

<span style="color:#323232;">tar -h
</span>
woelkchen ,
@woelkchen@lemmy.world avatar

Just tar, no arguments. Does nothing, still a valid command, no?

foobaz ,

Exit code 2 -> boom

rrconkle , 

<span style="color:#323232;">tar: You must specify one of the '-Acdtrux', '--delete' or '--test-label' options
</span><span style="color:#323232;">Try 'tar --help' or 'tar --usage' for more information.
</span>
doctorzeromd ,

Boom. tar --help for anyone wondering

Steamymoomilk ,

I just use ouch
