@AvinashRaj - yes. I am here.

[pqr]
para1=333
para2=765
para3=1345
input ^^
how to replace 765 to 999
it's a large file
there is one pqr block
the only thing we known is
it's just after [pqr] and para1.
This could be possible through sed.
But i donno how?
mikeserv
mikeserv
@Avinash - 2cd line from [pqr]?
Avinash Raj
Avinash Raj
yep.
it could be possible through pattern space like when the string [pqr] is smelled, sed appends the next line to ps and again the next line to ps. Finally it does the opreation on third line.
mikeserv
mikeserv
sed -n '/\[pqr\]/{n;n;s/...$/999/p}'
Avinash Raj
Avinash Raj
07:48
letme try
it shows,
$ sed -n '/\[pqr\]/{n;n;s/...$/999/p}' r
para2=76999
and i want the whole file remains unchanged except this.
mikeserv
mikeserv
Oh. Remove -n and p and change s/// to this: s/... *$/999/
Or actually this is better s/[^=]*$/999/
@AvinashRaj - that does it, yeah?

@mikeserv works but i want 999 only

You want the whole line to be 999 or you want para2=999?
Avinash Raj

sorry, space in my input.
mikeserv
mikeserv
Or para2=76999?
Avinash Raj
Avinash Raj
works, thanks.
mikeserv
mikeserv
Oh, cool. I thought it was spaces at the end of the line, which is why I recommended the [^=]*$ instead as it should replace everything following the last = in the line - spaces and all - w/ 999
Avinash Raj
Avinash Raj
so n; appends the next line to PS.
mikeserv
mikeserv
08:16
No, N does that. n overwrites current PS with the next line.
Avinash Raj
Avinash Raj
Pattern space still a tougher one for me.
Ahhh :(
mikeserv
mikeserv
n is faster generally. But N will get you both lines in PS with a single \n dividing them.
Avinash Raj
Avinash Raj
Both lines means current and the next.

@AvinashRaj But using P and D with N makes multiline sed a pretty easy thing. See my latest update to that ls question.

@mikeserv Thanks.
Avinash Raj
Avinash Raj 
sed '/^\[pqr\]$/{n;n;s/...$/999/g}' r
why this won't work?
mikeserv
mikeserv
Because you're searching for any line that ends in either p q or r.
Or, well, you were. You need to remove the g - if it has any effect it at all it will be contrary to your purpose and GNU specific.
Also I suspect you have some more whitespace on the pqr line.
Instead use the s/[^=]*/999/ like I suggested.
You might do something similar with your function address like /[^] pqr[]/!{n;n;s/[^=]*$/999/}
Avinash Raj
Avinash Raj
yep. there is a space.
sorry.
mikeserv
mikeserv
08:31
That should only select a line containing any one of those characters and nothing more. No problem - it was nice to be right.
Nah - that's a bad idea. Better to do /^ *\[pqr\] *$/...
If there's a chance of two = on the replace line s/[^=]*$/999/ will always only replace from the last on. If you'd rather do it from the first to the end: s/=.*/=999/
In the case there is no = on the line [^=]*$ will replace the whole thing but =.* is a noop.
their behavior is identical for a single = though.

@polym I (and others) rejected several of your suggested edits. It is not necessary to add "Question:" in front of a question, if it is properly worded and has a question mark. Also not every word that might be a command should be backticked, you should only do so when it is actually used as a command or filename.
In particular it is not a users home directory since that directory is not name "home" and Perl should never be Perl (there is no such command, and only be changed to perl if it refers to starting the Perl interpreter.

@Anthon Ok thanks for the info. I thought of adding Question to highlight the question to make it more pleasant to the readers eye.

@polym there is always a tradeoff, but the tendency here is to keep things terse and remove unnecessary stuff (like greeting at the beginning and thanks, username at the end). The "How ...?" should be enough especially if in a new paragraph. If the OP puts it there, I normally leave it, but adding it is IMHO not necessary.

Braiam
Braiam
@terdon "but I don't see why" is the thing I'm wondering too
terdon
terdon
It is a programming question but there is no code involved, It's more of a theoretical "how should I do this" and it seems to be more related to the API side of things than to any programming issue.
@Anthon ^^ ?

@terdon IMO, SO doesn't like "how do I write X piece of code"

@terdon if you are dealing with interrupt level stuff, thats deeper than the API (system calls), you are in kernel internals / driver territory

@Braiam still kernel internals and not something a user would ever deal with. kernel programmer sure.

Dunno. Coding for nix is on topic and this seems to be a valid question about the *nix internals and how interrupts are handled.

He doesn't state what language but I'm guessing it's C. It's a programming Q.

@slm Yet it has no code. And we consider programming for *nix on topic within reason. I don't really know enough about it to judge whether this was within reason or not though. I take it you consider it not to be?
slm
slm
@terdon - yeah that seemed a bit too deep down the coding hole for here. I'm familiar with the spinlocks he's referring to.
It's a construct for locking resources. Given the other Q he referenced is already on SO it seemed correct to put this one there too. His Q is a refinement of the other Q.

By the way @slm (and any other perl person), this is interesting:
Did you double check the output files of the perl version?

So I tested the perl one here (cut n' paste) and O_O it created 1000 files but all the files were empty... — goldilocks 8 mins ago

OK, no errors there. That's very weird. Attempting to load a non-existant module should give an error message. Silence implies success.

Hold on, this might mean something. 
$ sudo cpupower frequency-info
analyzing CPU 0:
  driver: intel_pstate
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 0.97 ms.
  hardware limits: 1.60 GHz - 3.70 GHz
  available cpufreq governors: performance, powersave
  current policy: frequency should be within 1.60 GHz and 3.70 GHz.
                  The governor "powersave" may decide which speed to use
                  within this range.
Specifically, available cpufreq governors: performance, powersave

Yes, but also show us the contents of /etc/conf.d/cpufreq as I asked earlier

@terdon No such file or directory.

OK, try powersave anyway.

No error message, which I'm assuming is good, but I can't tell if the changes stuck because it was already powersave.
> intel_pstate offers only two governors, powersave and performance. They (intel) claim that the intel_pstate "powersave" is faster than the generic acpi governor with "performance"

Q: Setting CPU governor to on demand or conservative on Arch Linux

lviggianiI'm struggling with cpupower on ArchLinux. I want to set governor to ondemand or even to conservative. First if I do $ sudo cpupower frequency-info --governors, I only get performance powersave. So I look for available modules like this ls -1 /lib/modules/`uname -r`/kernel/drivers/cpufreq/ ....

linux power-management cpu-frequency
Setting it to performance appears to have worked!

You're welcome. Still strange that you don't have ondemand but I guess it's a hardware thing.

Oh. I started up Minecraft again and got more unexpected lag spikes. I thought "maybe I have to reboot for it to take effect" because I used windows for most of my life and old habits die hard. Now my computer is showing all signs of working except for the part where no signal is being sent to my monitors.
So I'm exactly where I was when I got into this mess.
I can ssh in no problem. Anything I should try before I reboot it again and hope it noticed my monitors this time?
Oh, right, I moved chat rooms and should probably give context. This whole ordeal started with this message in superuser.SE:

Hey, I'm going to ask for some advice here because I don't feel like it would make a good superuser.SE question, but if I'm wrong I can post it as one. If it would make a good question somewhere else I'll post it there, but you guys seem like the best fit.

I was getting random lag spikes in a game I'm normally able to get 60 fps in without any trouble and I thought there might be some processes running that I had started by accident, so I rebooted my machine. The co…

I don't know how often you're supposed to clean out the dust from a computer, but I'm going to hazard a guess that I shouldn't have put it off until it hit "a couple years".

You should clean it when it gets dirty. No other rules :)

Q: Filetype and dereference when listing directory with LS command

Felipe LeãoI'm trying to combine arguments to the ls command to list a directory content. What I'm basically trying to achieve is listing the directory dereferencing all links, but showing explicitly that the item listed is a link. I've tried combining the --dereference and --classify options, but instead o...

Is it possible to get find's -printf to print non-printing characters in full like find -ls does?
For example: 
    $ find .  -name '*line' -ls
    16646172    0 -rw-r--r--   1 terdon   terdon          0 Jun 30 23:39 ./a\ new\nline
$ find .  -name '*line' -printf '%p\n'
./a new?line
It seems strange that -ls can do it but -printf can't.
It prints correctly when the output is not a terminal.

Please help disambiguate key. This tag must go.
terdon
terdon
@Gilles What do you suggest? Delete key, create encryption-key?
Gilles
Gilles
@terdon retag all the posts that have it to whatever is appropriate
terdon
terdon
Yes, doing so now but should there be a encryption-key?
Gilles
Gilles
I doubt that we'll need to create any tag. Keyboard keys → keyboard-layout or key-mapping, encryption keys → encryption, etc
terdon
terdon
Or just leave it at encryption?
Gilles
Gilles
22:50
if it's for encryption, yes
why aren't keyboard-shortcuts and key-mapping merged? keymap is already merged with keyboard-shortcuts
terdon
terdon
Why do you want to map keyboard-shortcuts with key-mapping? They are very different things.
Huh? keymap is what? Why?
Gilles
Gilles
@terdon uh? what's the difference?
terdon
terdon
I think of mapping as assigning a keyboard key to a symbol and shortcuts as assigning a combination to an action.
Braiam
Braiam
@Gilles I think you are refering to key-mapping and keyboard-layout
terdon
terdon
Mapping for things like "How can I switch Ctrl with Alt on my keyboard" and shortcuts for "How can I open a terminal emulator with a keyboard shortcut"
Gilles
Gilles
22:54
@Braiam no, on the contrary
@terdon that's keyboard-layout
key-mapping and keyboard-shortcuts are used indifferently for associating an action to a key (or key combination)
terdon
terdon
Layout is part of it yes, but I don't see any relation between shortcuts and mapping keys.

Bash, zsh, emacs, vim and many others call keyboard shortcuts “key mappings”, stored in “key maps” (or “keymaps”)

@Braiam I'm not saying that all questions are tagged correctly. But look at the other 90% of key-mapping. It's about keyboard shortcuts.
