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.

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

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

[–] [email protected] 58 points 1 year ago

And also tar -the fuck is in this file

[–] [email protected] 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).

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.

[–] [email protected] 9 points 1 year ago

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

[–] [email protected] 37 points 1 year ago (2 children)

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.

[–] [email protected] 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!

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. ;)

[–] [email protected] 9 points 1 year ago

Nah I just use 7z

[–] [email protected] 20 points 1 year ago

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.

[–] [email protected] 19 points 1 year ago (8 children)

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

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

[–] [email protected] 17 points 1 year ago (2 children)

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.

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

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

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.

[–] [email protected] 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.

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... \^\^
[–] [email protected] 16 points 1 year ago (1 children)

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.

[–] [email protected] 9 points 1 year ago

Yes, but still tar options are kinda janky.

[–] [email protected] 15 points 1 year ago (3 children)

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

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.

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

[–] [email protected] 9 points 1 year ago (2 children)

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

Simple:

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

[–] [email protected] 23 points 1 year ago (1 children)

Create ze vuking file

Xtraxt ze vuking file

I always just use

"eXtract Zee Files"

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.

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

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)
