It should be a crime to directly link XKCDs images without the corresponding page.

I understand and sympathize with Rob on a spiritual level.

I remember it like this:
tar -extract ze file
and
tar -compress ze file

[-] Atemu@lemmy.ml 58 points 1 year ago

And also tar -the fuck is in this file

[-] exscape@kbin.social 22 points 1 year ago

z is for gz files only though, there are plenty of others. xf autodetects and works with all of them (with GNU tar att least).

[-] blackstrat@lemmy.fwgx.uk 55 points 1 year ago

I hope whoever thought -l should mean "check links" instead of list has a special place in Hell set aside for them.

I have no idea what print a message if not all links are dumped even means.

[-] happyhippo@feddit.it 9 points 1 year ago

Was gonna say this. Why TF is list not -l as...everywhere else?

[-] Maoo@hexbear.net 37 points 1 year ago

No no it's this:

  1. Decide you've gotta use tar.

  2. man tar

  3. Guess-and-check the flags until it seems to work.

  4. Immediately forget the flags.

[-] bahmanm@lemmy.ml 10 points 1 year ago

That was my case until I discovered that GNU tar has got a pretty decent online manual - it's way better written than the manpage. I rarely forget the options nowadays even though I dont' use tar that frequently.

I always did Xtract Ze File but I will add Vucking from now on, thanks!

[-] Zacryon@feddit.de 29 points 1 year ago

Ah yes, that's the linux community as I know it. There is one thing someone wants to achieve and dozens of ways to do it. ;)

[-] pineapplelover@lemm.ee 7 points 1 year ago

Nah I just use 7z

[-] aard 20 points 1 year ago

You also don't need the dash for the short options.

Also, if you're compressing with bzip2 and have archives bigger than a few megabytes I'll like you a lot more if you do it with --use-compress-prog=pbzip2

[-] sebastiancarlos@lemmy.sdf.org 30 points 1 year ago* (last edited 1 year ago)

You also don’t need the dash for the short options.

True, but I refuse to entertain such a non-standard option format. It's already enough to tolerate find's.

[-] aard 17 points 1 year ago

Technically the notation with dashes is the non-standard one - the dash form is a GNU addition. A traditional tar on something like Solaris or HP-UX will throw an error if you try the dash notation.

[-] sebastiancarlos@lemmy.sdf.org 25 points 1 year ago

It's also traditional to eat raw meat, but we discovered fire at some point.

[-] aard 8 points 1 year ago

Don't try to take my raw ground pork away from me.

Those are straightforward; it's the remaining 900 options that are confusing. I always need to look up --excludes and always get --directory wrong, somehow.

[-] miniu@programming.dev 17 points 1 year ago

Why when explaining, giving examples of shell command are people so often providing shortened arguments. It makes it all seam like some random letters you have to remeber by heart. Instead of -x just write --extract. If in the end they endup using the tool so often they need to write it fast they'll check the shortcuts.

[-] catacomb@beehaw.org 7 points 1 year ago* (last edited 1 year ago)

I don't even mind the shortened arguments too much, though it doesn't help. It's more that every example seems to smush them together into a string of letters.

I would have found

tar -x -f pics.tar ./pics

to be clearer when I was learning. There's plenty of commands which allow combining flags but every tar tutorial seems to do it from the beginning.

I don't think tar is actually hard, we are just in the time where we externalize more information into resources such as Google. Its the same reason why younger people don't remember routes by name or cardinal direction as much anymore.

side note: $ tldr is much better than man for just getting common stuff done.

[-] Aatube@kbin.social 9 points 1 year ago

Yes, but still tar options are kinda janky.

[-] d00phy@lemmy.ml 15 points 1 year ago

The “-“ is often not necessary. I use it as a guide to see how long the person running tar has been using it.

Example:

tar -xf file.tar == tar xf file.tar

[-] Gecko@lemmy.world 14 points 1 year ago

Or just use long-forms like

tar --create --file pics.tar ./pics

instead of

tar -cf pics.tar ./pics

or

tar --extract --file pics.tar```
instead of

tar -xf pics.tar


which is honestly way easier to remember... \^\^
[-] nucleative@lemmy.world 13 points 1 year ago

I have to Google for this everytime. What I can never remember is how to check whether I should put my tar.gz into the subfolder first or risk getting a thousand files sprayed into my homedir.

I know the basics off by heart. Not the hardest command syntax to learn all things considered.

The most annoying would be the growing collection of "uber commands" which are much more of a pain in the ass - aws, systemctl, docker, kubectl, npm, cargo, etc. - the executable has potentially dozens of subcommands, each of which has dozens of parameters.

"eXtract Zee Files"

[-] 520@kbin.social 9 points 1 year ago

Simple:

tar -(whatever options you want here, my go to is xvzf or cvzf) archive-name.tar file/folder-to-compress

[-] cooopsspace@infosec.pub 23 points 1 year ago

Create ze vuking file

Xtraxt ze vuking file

just now realizing that .tar files aren't compressed by default, and that that's the reason why it's always .tar.gz

As a mnemonic I usually read the "f" as "fucking":

  • tar, compress fucking pics.tar.gz with junk from ./pics
  • tar, extract fucking pics.tar.gz

That's only for scripting though. Most of the time I simply right-click the directory or archive, and let Engrampa deal with it.

[-] Blackmist@feddit.uk 8 points 1 year ago

Yes, that's all very well, but you'll still need to find that image the next time you want to use it.

[-] Anticorp@lemmy.ml 7 points 1 year ago
[-] peppy@lemmy.ml 13 points 1 year ago* (last edited 1 year ago)

lists the files in the archive. So you don't need to extract the entire archive. Useful for huge archives.

[-] twelve12@lemmy.ml 7 points 1 year ago

dtrx is the way to do it. It's short for "do the right extraction", and it just works.

Also, all you have to remember for tar is "-xtract -zee -vucking -files" (extract the fucking files, but first letters only)

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
