Could someone help understand a problem I had? The simple form of that problem is: I wanted to copy a file via samba over the network but only about 1.8M were transfered and after that the io stalls at 0%.
Your script leaves VT undefined (unless it's set in the environment, but that leaves Date unused).
A simpler script:
#!/bin/sh
if grep -q -Fx 'Jun212018' /home/file.txt; then
echo 'Date has Matched'
fi
This prints the string if the date Jun212018 matches exactly on a single line in the f...
@Kusalananda I used to ask those kind of question and it took me a while to understand why no one would answer... Now I try to explain it but it feel like an endless circle of repetition :D
@Kiwy Most of the time, the user is simply unused to asking questions, and does not know how to provide relevant information that makes sense. To them, it really just does not work. To us, it fails in specific ways, and this would tell us what's wrong.
We're like medical doctors that are supposed to diagnose a symptom without ever getting to see the patient.
I run a debian Webserver with nextcloud. Every night a backup job (storeBackup) is scheduled and it only succeeds in very few cases.
But every night the journal is full of OOM Errors (see below).
The machine has 16G RAM, therefore I am wondering, what is so much RAM consuming.
Output of journal...
Could I have someone's eye on this one, I really feel like the backup script is CPU and IO intensive and is the cause of the problem, also how can a system misses RAM when 11GB out of 16GB are cached and not even actual leaving data ?
While I find that we can read some manuals about Library calls (C library functions) & acsii in Linux. But I still do not find any manual about C precedence order so far.
So you can recommend other useful manual about C now. Thank you!
PS: Note that the manual can be accessed via man command in...
Is there a package on Debian or some other Linux media that provides documentation for the C language? I mean in particular man pages. Eg. so that I can check docs for typedef or other basics (and possibly advanced concepts).
I believe that libc6 is still under quite active development. Since the C API is presumably not changing very fast, if at all, does anyone have a clear sense about what kind of development is going on?
I know I could go and look at the repos itself, but I was hoping for a high level summary.
And this question may or not be suitable for site (I think it's a bit vague), but feel free to comment either way.
@FaheemMitha The C API is changing — e.g., the kernel adds new features through the syscall interface. Programs want to use those new features. Often that goes in libc.
@FaheemMitha I was wondering what you are planning to do with the recording you take of these criminals, if you are able to obtain it. If you turn it over to corrupt police isn't there a possibility of them not doing anything and this whole thing will just come back to you in a negative way?
@Jesse_b Oh. No, if I was to use such a thing, it would be in court. But this is all hypothetical. And it wouldn't just be in this instance.
I mean, I could use it generally for recording conversations. Though, it's true people often don't like themselves recorded.
So it would probably tend to be for use with not nice people. A record of things they said so they can't pretend they didn't say it later. Again, all hypothetical.
In tangentially related news, it looks like Amazon may not pick up my defective H5 at all.
I've no idea why. It's never happened before. The Amazon rep guy said to me that my refund had been processed, and that if they didn't pick up the recorder, I got to keep it.
@FaheemMitha That git log you linked to is full of them. The ELF BPF programs stuff is a new kernel feature. Scroll down a bit and you find SHM_STAT_ANY, also a new kernel feature
@derobert Oh. Those are just examples, right? You don't happen to know what they are?
@Jesse_b If they really don't take it back, I was thinking that I could to get it replaced under the (supposed) 1 year warranty. Though I can't be sure that there is a real warranty.
@Jesse_b It refuses to work with the shipped micro-SD card. And I bought another cheapo card, and it doesn't work with that either.
It could just be a won't-work-with-cheapo-card thing, but the unit also hangs hard from time to time when trying to test the SD card, which I figure is a bad sign. You have to take out the battery to make it shut down.
@derobert Oh. I haven't been following LWN recently. And in any case, I often don't understand their kernel stuff. Though you and @StephenKitt might.
Did you know Stephen is a stealth kernel hacker?
@derobert Did I mention it's nice to see you here again? Don't mean to gush...
@FaheemMitha No, nothing like that. What did happen is being very busy at work for a while. Its a really great idea time your internal CA to expire at the same time Wheezy LTS goes EOL.
Great in the sarcastic sense, of course.
Of course, that wasn't planned — the CA expire date was picked 10 years ago, for example.
@derobert Huh. You've been gone a long time. Was it a big job?
Busy at work. A mixed blessing, I suppose. Do they pay overtime?
Also, you know about lots of stuff. What's your level of expertise on sound recorders? I can't remember if I asked. Specifically, do you know anything about the Zoom series?
Nope. Haven't really had to put in any, though. But it did give me something better to do during all the otherwise free (e.g., waiting for computer) time at work instead of chat.SE :-/
Nobody else seems to have. The Sound SE doesn't seem particularly interested in talking to me.
I briefly had the attention of one of the mods, but now he seems to have returned to the default position of ignoring me. He did give me some very useful information first, though.
I figure it could sometimes be useful. And the Zoom series also double as USB mics on Linux, which could be useful. Though I haven't figured out where the drivers live. And Zoom doesn't officially support Linux, so who is writing the drivers?
@derobert Ok, well not right now. It's insanely late here, and I have a few things to do before I got to sleep. But do stick around. As you can see, you miss things by not being here.
In my testing of my new Zoom H5, I foolishly did not test the standalone recording capabilities, which require a working SD card.
I tried using the included SD card. When I tried to format it, I got an error. When I tried the quick performance test, it alternately gave me NG, and just froze part...
Well if using recording devices as a sex toy is excitement, I certainly have none of that in my life
@FaheemMitha I suppose, I also see a few quite a few recording related questions. I just picture that site having a lot of home theater type enthusiasts which might not be very familiar with recording technologies
