Totally is a real question.

I edited it a bit

But I might have misinterpreted...

Eliah Kagan

Looks fine to me.

So, what should be done on this answer? Originally it didn't contain an explanation and was dangerous because it gave the impression that unlink is specifically for symlinks. (People delete their regular files all the time assuming they'll just get a harmless error message if they use the unlink command on them.) Then it was edited by someone else and is no longer dangerous, but the explanation they added is totally wrong: unlink isn't an alias of rm.

Also it has 13 upvotes, all but one of which were cast after the edit.

Zanna

12:11 PM

Oh dear...

Possibly we should just correct the explanation?

Eliah Kagan

I guess so. A better explanation would be "unlink is like rm except worse in all these ways (list) so don't bother using it hardly ever." I doubt that would've garnered 12 upvotes though.

Leave Closed, but I've flagged the first comment as rude or abusive.

I feel pretty confident that wholly unsubstantiated accusations against an OP (or anybody) are a violation of the be-nice policy both due to the common understanding of what it means to be nice and under the specific example about assuming good intentions.

@EliahKagan agreed, even if the question sounds weird (i guess due to language barriers) it doesn't seem that hes trying to pirate anything. And even if, this comment could have been worded more sensible.

this sounds more as if he hasn't set the execute bit or if hes using the app-store version of minecraft that his OS doesn't allow the execution and he has to enabled 3rd party sources to install and ise the app

Eliah Kagan

12:54 PM

Why would that have worked?

Videonauth

1:11 PM

@EliahKagan what i dont get is why putting the grep into a variable and then outputting this

why not directly grep and be done with it when the variable is not needed for something else later on

Eliah Kagan

Do you mean, why is the OP making a script at all?

Videonauth

no the script itself

if [ "$#" -eq 0 ]; then
          echo "Please enter an argument"
    else
          $result=`grep $1 Sales.csv`
          echo $result
    fi

Eliah Kagan

Oh, you mean, why is the OP putting it in a variable?

There is no good reason.

Videonauth

yes i think so ;)

and the rest well is normally redundant too

if he not uses ascript he puts in his argument directly in grep

Eliah Kagan

The main problem with that script is that $1 is not quoted.

This will actually usually fail with that grep command.

Yes, it is possible to come up with trivial cases where the regular expression contains no IFS whitespace and no globbing characters (*, ? and [ are all both regex metacharacters and globbing characters).

In all currently used Bourne-style shells except zsh, word splitting and filename expansion are performed on the results of unquoted parameter expansions. (zsh will also do so if it's emulating a shell that does, such as if is being used as sh.)

ek@Io:~$ test='xenial main'
ek@Io:~$ grep "$test" /etc/apt/sources.list
deb us.archive.ubuntu.com/ubuntu xenial main restricted
deb-src us.archive.ubuntu.com/ubuntu xenial main restricted

Videonauth

yep

terrance answer is then slightly wrong too, and for the question itself backticks are to be avoided and it should be used $() instead

still ok for learning, tho but the script in itself is purely redundant

grep is not that complicated line in itself so it should be wrapped

i would make wrappers for comlicated lines like this

function tcd(){
history | awk '{CMD[$2]++;count++;}END { for (a in CMD)print CMD[a] " " CMD[a]/count*100 "% " a;}' | grep -v "./" | column -c3 -s " " -t | sort -nr | nl |  head -n10
}

and im sure this could be golfed down even to a more simple line

or this

alias toclip='xclip -sel clip'

where i pipe into this command and dont want to type it all time again

this way i can simply do command | toclip and have it in the clipboard

if it offers a pipe

not to speak about if he goes over a big file lets say multiple GB in size with the version using a variable he will have build a real memory hog

depending on what he searches for in this file

What. The. Heck. askubuntu.com/a/975667/518562

How could only apt-get update have fixed it??

Videonauth

@AndroidDev possible PEBKAC

Eliah Kagan

2:31 PM

Super unclear.

@AndroidDev What does NSS_VersionCheck actually do?

Zanna

I thought ah they found an instruction to edit a file with nano to fix the typing problem, but they can't launch nano, because there's an "a" in it haha

Eliah Kagan

That could well be. Who knows! You may want to comment though. You could ask a number of other clarification questions related to that, too, like whether or not they can ever type a, did they have to use another machine to write their Ask Ubuntu question so it could have a in it, and so forth. This sounds silly but I am not making fun -- I do believe this would be helpful.

I mostly like this tag wiki but can the first sentence be reworded in such a way to avoid misleading people? Right now it makes it sound like if you make a file whose contents are a path then that's a symlink.

> A symbolic link is a file that merely contains a text string which is a path to another file or directory.

Zanna

7:15 PM

of course, but what do you suggest?

Eliah Kagan

7:26 PM

I'm not sure what a good way is.

Btw I think the reason this question hasn't gotten a fifth close vote yet, for no repro, is that the answer in which the OP reported switching to Arch was deleted (and was only recently turned into a comment). So if somebody who sees this wants to cast that vote...

Zanna

@EliahKagan I will leave the tab open and hope my brain is working better tomorrow haha

Eliah Kagan

9:28 PM

Currently unclear. Depending on the OP's reply (or lack thereof) it might later become clear or it might be no repro.

Videonauth

9:58 PM

@EliahKagan Closed

Eliah Kagan

Thanks.

This edit suggestion deliberately vandalizes the question to make it misrepresent what the OP did. It also removes some relevant path information. It needs another rejection.

Videonauth

@EliahKagan ypu sure you linked the right one, the one im seeing there is a legit edit tbh, hes only removing the username from the prompt

Eliah Kagan

Yes.

It replaces the entire prompt, which indicates a root shell (and shows the current directory), with another prompt that the OP did not actually have, that indicates a non-root shell. It is part of a strategy to deface the post in order to admonish the OP not to use root shells. See the comment on the post.

Videonauth

well i rejected it

Eliah Kagan

Thanks.

just woke up after having a long afternoon nap

Eliah Kagan

Good ~~morning~~ afternoon/evening!

Videonauth

ah well i love Sundays, i normally even if i don't leave my home hold me to a strict time to stand up and do household stuff etc, but on sundays i dont go after that rule

im at home almost 24/7 due to a psychical illness

Videonauth

10:17 PM

Do i read this answer right? askubuntu.com/a/970026/522934 should'nt this be an edit to the question?

Eliah Kagan

10:28 PM

If it's the OP's solution, then it's appropriate as a self-answer.

Videonauth

mhmm ok, for me it reads more like a question tho, but well, actually going through all the minecraft questions and for sure what i see there is the GLX13 openGL context missing question over and over again those should/could be possibly merged into one making the answers a community wiki since noone cared to mark answers as accepted

good example askubuntu.com/questions/820764/minecraft-crashing if you look in the suggested questions on the right side you'll find at least ten of the same question, all about OpenGL context not found and all partly answered but none with an accepted answer you could point to as a dupe target
