perhaps there's a new user trying for some voting badge? (civic duty, suffrage, or electorate)
... or vox populi
wild theory, but there's one user who's recently earned both suffrage and vox populi ; perhaps well-intentioned (simply going for fake internet trophies with high-rep users on the site) without realizing that the voting would be reversed
@deostroll First of all, you should not pipe the output of find to grep. Instead: find /path -type f -name '*.xml' -exec echo x \; | wc -l This would output an x for each found file and wc would count the number of xes. This allows for pathnames with newlines to be counted properly. If you want to count two filename suffixes, use e.g. find /path -type f \( -name '*.xml' -o -name '*.dmn' \) -exec echo x \; | wc -l
Leave regular expressions for text, don't use it on filenames.
The alternation (|) that you are trying to use is an extended regular expression. grep does basic regular expressions by default. Use grep with -E to enable extended regular expressions, but don't use it on pathnames.
@terdon, thanks again about the tags. I hope there aren't still others left with a conflicting language, but now we at least know what the issue is. :)
Had to crank up the font to 24p in my terminal now. I'm getting headaches. Will have to get new glasses soon... possibly even separate ones for work. :-/
@Kusalananda Investigate also exercising the eyes. No miracles, but it does help. It saved me in my 20s for using glasses for a minor problem.
@Kusalananda Basically had to go to the hospital, using special lenses and doing repetitive tasks with them...nonetheless some small exercises can be made at home.
I do find the sun exposure terrible advice. I have did eyes exercises in a specific program in the hospital in my middle twenties instead of being given glasses, and 2 and half decades after I still do not use glasses, so I guess something must have worked ;)
@jimmij come on. Closing this as a dupe of the Kali is hard is just a slap in the face of the OP. The problem is that the URL is bad, so we can close as too localized, it has nothing to do with Kali. — terdon ♦2 mins ago
@terdon The question is also a slap in the face being asked here. I am not fond of overly lazy cerebral reguargitation here. .but I do understand your points. I have seen the comment.
@RuiFRibeiro Then downvote it, or ignore it, but please stop using the Kali question as a target unless it actually makes sense to do so: the OP is attempting to use Kali as a regular OS.
@StephenKitt Of course they are! Unfortunately, we have some users who seem to think this site is for experts only. I have no idea where they get that from.
I've been seeing comments from a few users lately along the lines of "if you don't know this, you shouldn't be asking here". That is a serious problem.
@RuiFRibeiro you can set your own bar to anything you want for questions you’ll answer; but I think the appropriate response to questions you don’t want to spend time on (helping the OP improve them, or answer them) is to ignore them, not comment on them that the user shouldn’t have dared bother you in the first place.

Obviously downvote and vote to close as appropriate too, when it’s appropriate.
I think I'm on the same page; I "worry" that we'll get too many knee-jerk VTC-dupes for any/all Kali questions, based on their poor history, but I don't know that I'll be saving many Good Questions, so I'm not going to fight for them. — Jeff SchallerOct 22 '17 at 20:45
They are, sadly, more appropriate here, seeing the distro is based on a Linux kernel.
In order to minimise the impact on those of us who have little patience for the numbats that think that installing Kali will make them l337 haXX0r5, please—as a public service— ensure that they are all tagged k...
And no, I don't have a real solution to the problem. I do completely agree that we seem to get loads of posts about Kali from people who should not be using Kali.
Maybe we should set up a different close reason. Something like "Kali is off topic here unless your question clearly shows you have the required level of experience to be using a tool like Kali". But I don't see how that would go down very well.
For one thing, nobody would agree on whether the OP is indeed experienced enough or not.
Part of the issue with Kali questions is that people end up reacting to them based on the fact that it’s Kali, irrespective of whether the question is Kali-related or not. Ask a question about AWK, and people will fall over themselves answering it; but ask the same AWK question with kali, and it will be obliterated.
or the stock download has a simple typo somewhere that hobbles the system, a la one of those Certification exams where they cripple the grub.cfg or mess up the root shell
I would suggest some warnings in the tag wiki, but I've despaired of people looking there, so I don't have any good ideas either.
perhaps Kali users will just have to show more persistence and a quick Stack Exchange learning curve, to edit their questions into shape for reopening. An unfair slope, but that's where it is.
@StephenKitt there is a "funny" line between people who jump in with answers (sometimes 30 lines long) versus "we're not a script-writing service"
@JeffSchaller Sometimes those "write me a script" questions give me a good idea for something I could use at work, and in those cases I usually will try to write it
@Jesse_b awesome! I'm not against that at all -- this is a Q&A site after all -- but there's some sort of fine line / trigger about certain questions that bring out the "but you haven't tried so I'm not going to"
but there's 3000 CSV-parsing questions (for a made-up example) that also showed no effort and got 5 responses
I suspect it's down to the amount of interest and skill overlap -- if you're good at CSV parsing or awk or whatever, the bar's lower for you to answer; and whether the problem sounds interesting to you or not
@RuiFRibeiro I don't understand why so many people are ashamed to pee near other people. We used to have 90 seconds for 70 people to pee in a 5' long trough
There were people literally standing on the shoulders of other people in order to pee
@Jesse_b at home, between me and wifey wc is game at any time whether one of us is there or not, but I do it better alone. Morning we are both working, forget about someone being alone there.
@Jesse_b (that is the price of living in the city nearby everything....small apartment)
@StephenKitt I don't know, I've yet to find anyone making pizza outside of NY/NJ. I've had some halfway decent cheese/tomato pies but I wouldn't quite classify them as pizza :p
There is actually another place down the road in hoboken with far superior sauce and just higher quality ingredients in general but their crust isn't quite there
And for some reason I just prefer that gritty boardwalk style slice that has been sitting under a heat lamp for an hour
What's the proper way to chain redirections under POSIX sh? I'm certain I've done this before: tar -tf "${FILE}" 1>&2 2>/dev/null Where I redirect stdoutto stderr, then stderr to /dev/null, but that's not working properly.
When I say under POSIX, the shebang is #!/bin/sh, but we know for certain that bash will be on the target system.
I'd not prefer a bash-specific way of doing this though.
because the redirection happens right away, so stderr was still going to screen under my example, so stdout ended up on screen, THEN stderr was redirected to /dev/null?
Plot: Filipus Klutiero is using shellshock to rob international banks and the worlds top intelligence agencies are unable to stop him. They pull in Stephane Chazelas to help track down and stop this hacker. He has a female liaison from the CIA that can't help but fall victim to his charm. Halfway through Filipus kidnaps the CIA liaison and Stephane has to go rogue to save her.
The ending scene takes place on top of the Burj Khalifa in Dubai where Filipus is holding the CIA liaison over the edge and gets into a gunfight with Stephane. The liaison falls over the edge and Stephane has to dive off to catch her mid fall and deploy the parachute he happened to be wearing
Like a computer explodes sending a processor flying that cuts the arm of one of the bad guys. As he's holding his hand over the cut to stop the bleeding Stephane can say "You know you should really..._patch_ your systems"
I am trying to understand how flex works step by step.
In the following first example, it seems that main() calls yylex() only once, and yylex() generates all the tokens for the entire input.
In the second example, it seems that main() calls yylex() once per token generated, and yylex() ge...
@Tim, I can't remember much about flex, but the first snippet there doesn't have any return statements in the lexer, so it probably doesn't really return anything. Except implicitly at the end, I assume.
awk works like: for each line: for each (pattern, action): if the line matches the pattern, then take the action on the line end end
What is it like for flex?
for each character: for each (pattern, action): if a substring started from the character matches the pattern, then takes the action on the match end end ?
Does "return" in an action mean to return from a call to `yylex()`?
In awk, if a line matches multiple patterns, the actions for **all** the matched patterns will all be taken. In flex, if a character starts some substrings that match multiple patterns, **only** the action of longest matched pattern will be taken?
Unfortunately most of the people trying to use kali have no business using kali. Everyone I have ever met that uses kali is a windows user who's first experience into linux has been kali
They brag about it like it makes them some kind of "hacker". "Hey man guess what, I installed kali on my laptop last night!" That's great, maybe try getting familiar with a normal distribution first though?
"Got my drivers learning permit and I bought an F1 car. Need help learning how to put it in gear"
Well I think the key part of that metaphor is that nobody should be exposed to an F1 car before first getting years of experience driving and racing lower tier cars. One will almost certainly die if their first driving experience is in an F1 car
@ilkkachu Another aspect of the metaphor would be that an F1 car is a purpose built machine that should not be used for daily driving but only in the highest level of racing
Similar to the way kali should not be used for daily use but only for penetration testing
@MichaelHomer I'm on the fence on that one. I think using it as a close target is indeed a disgrace, but keeping it around as something to point people to feels like it can be useful. I've considered just closing it so it can't be used as a dupe but that should be properly hashed out on meta first.
