Try:

    kill -SIGINT processPIDHere

Basically &lt;kbd&gt;Ctrl C&lt;/kbd&gt; sends the `SIGINT` (interrupt) signal while kill sends the `SIGTERM` (termination) signal by default unless you specify the signal to send.

ctrl c just sends a SIGINT signal, but there is some other signals that is a little more soft. [http://www.gnu.org/software/libtool/manual/libc/Termination-Signals.html][1]

I think that you can use the the kill command to send some other signal.
(see man kill for more info)

Here&#39;s an example for mongod

To start the daemon from the command line:

    mongod &amp;


Then later

    kill -SIGINT `pgrep mongod`


If you control the long-running remote process, you could install a signal handler for SIGTERM (see `man signal` and `man sigaction` and the many SO questions on this topic), to cleanup nicely before dieing.

That is a very common thing to do.

Keep in mind as well in your signal handler, that it is like an interrupt handler in that you are *very* limited as to what you are allowed to do in it without corrupting the rest of your program. The best thing you can do here is set an atomic_t &quot;should_quit&quot; variable.

I am doing as below way

    killall -2 &lt;ProgramName&gt;

or 

    kill -2 &lt;PID of your process&gt;

I used to forget the the name of signal. i.e SIGINT/SIGKILL here so i am using number for that like killall -2 or killall -9

 

I&#39;m afraid that this is a very silly question, but I must be missing something.

Why might one want to use [String.Copy(string)](https://docs.microsoft.com/en-us/dotnet/api/system.string.copy)?

The documentation says the method

&gt; Creates a new instance of String with
&gt; the same value as a specified String.

Since strings are immutable in .NET, I&#39;m not sure what&#39;s the benefit of using this method, as I&#39;d think that 

     string copy = String.Copy(otherString);

would for all practical purposes seem to yield the same result as

     string copy = otherString;

That is, except for whatever internal bookkeeping that&#39;s going on, and the fact that copy is not `ReferenceEquals` to otherString, there are no observable differences - String being an immutable class whose equality is based on value, not identity.
(Thanks to @[Andrew Hare](#520932) for pointing out that my original phrasing was not precise enough to indicate that I realized there was a difference between `Copy`ing and not, but was concerned about the perceived lack of *useful* difference.)

Of course when passed a `null` argument, Copy throws an `ArgumentNullException`, and the &quot;new instance&quot; might consume more memory. The latter hardly seems like a benefit, and I&#39;m not sure that the null check is a big enough bonus to warrant a whole Copy method.

Thanks.





What&#39;s the use of System.String.Copy in .NET?

In the two following snippets, is the first one safe or must you do the second one?

By safe I mean is each thread guaranteed to call the method on the Foo from the same loop iteration in which the thread was created?

Or must you copy the reference to a new variable &quot;local&quot; to each iteration of the loop?

    var threads = new List&lt;Thread&gt;();
    foreach (Foo f in ListOfFoo)
    {      
        Thread thread = new Thread(() =&gt; f.DoSomething());
        threads.Add(thread);
        thread.Start();
    }

-

    var threads = new List&lt;Thread&gt;();
    foreach (Foo f in ListOfFoo)
    {      
        Foo f2 = f;
        Thread thread = new Thread(() =&gt; f2.DoSomething());
        threads.Add(thread);
        thread.Start();
    }

**Update:** As pointed out in Jon Skeet&#39;s answer, this doesn&#39;t have anything specifically to do with threading.

The foreach identifier and closures

I am running a long linux program in a remote machine, and I want to stop it, but my problem is that if I use the kill command then the program will exit without saving results. Normally what I do to finish the program is use &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;C&lt;/kbd&gt; and in that case the program saves the results, but right now I am not in the machine that is running the session so I cannot press &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;C&lt;/kbd&gt;.

My question is: is there any way to do in a remote way the equivalent of &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;C&lt;/kbd&gt;?

I am working on a daemon that monitors file events via inotify to trigger various types of events when files are accessed. I have read that watches are a little expensive, because the Kernel is storing the full path name of every file being watched.

How many watches would be too many?

Edit: Mostly, I&#39;m wondering .. have you ever seen a noticeable performance hit, if so, at how many watches did it happen? Yes, I have to monitor / recursively (however its a minimal bootstrapped system).

What is a reasonable amount of inotify watches with Linux?

I have a bunch of servers, on which I run experiments using `screen`. The procedure is the following :

 1. `ssh` to server XXX
 2. launch `screen`
 3. start experiments in a few tabs
 4. detach `screen`
 5. disconnect from the server

While the experiments are running, I can easily find on which servers they are by `ssh`ing to all servers and listing my running processes (using `top` or `ps`).

However, once the experiments are finished, how could I find on which servers I have a screen session opened (so that I can have a look at the output, relaunch them, etc.) ?

PS: my experiments do print their output to files, too... but this is not the point of my question.

How to list running screen sessions?

    sudo find /etc | xargs grep -i fedora &gt; searchFedora

gives:

    /etc/netplug.d/netplug: # At least on Fedora Core 1
    ...

But see the Fedora version in the `/etc/netplug.d/netplug` file. Is it serious?

How can I find the version of the Fedora I use?

I can understand `cmd` but not `cmd /c`. I was trying to invoke a java program from the current for which I use `Runtime.getRuntime().exec(&quot;cmd /C java helloworld&quot;);` There arises my doubt.

What does cmd /C mean?

I need to execute a PowerShell script from within C#. The script needs commandline arguments.

This is what I have done so far:

    RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();

    Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
    runspace.Open();

    RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
                
    Pipeline pipeline = runspace.CreatePipeline();
    pipeline.Commands.Add(scriptFile);
                                
    // Execute PowerShell script
    results = pipeline.Invoke();

scriptFile contains something like &quot;C:\Program Files\MyProgram\Whatever.ps1&quot;. 

The script uses a commandline argument such as &quot;-key Value&quot; whereas Value can be something like a path that also might contain spaces.

I don&#39;t get this to work. Does anyone know how to pass commandline arguments to a PowerShell script from within C# and make sure that spaces are no problem?

Execute PowerShell Script from C# with Commandline Arguments

I have this command that I run every 24 hours currently.

    find /var/www/html/audio -daystart -maxdepth 1 -mtime +1 -type f -name &quot;*.mp3&quot; -exec rm -f {} \;

I would like to run it every 1 hour and delete files that are older than 1 hour. Is this correct:

    find /var/www/html/audio -daystart -maxdepth 1 -mtime **+0.04** -type f -name &quot;*.mp3&quot; -exec rm -f {} \;

I am not sure of my use of the decimal number??

Thanks for any corrections.

EDIT
----

OR could I just use **-mmin 60**? Is this correct?

EDIT2
----

I tried your test, good thing you suggested it. I got an empty result. I want all files **OLDER** than 60mins to be deleted! How can I do this?? Does my command actually do this?

Is there a way using JavaScript to disable the ability to paste text into a text field on an HTML form?

E.g.
I have a simple registration form where the user is required to input their email twice. The second email entry is to verify there are no typos in the first email entry. However if the user copy/pastes their email then that defeats the purpose and I&#39;ve been experiencing users having problems because they&#39;ve input the wrong email and copy/pasted it.

Maybe I wasn&#39;t clear on my question but I am not trying to prevent people from copying (or drag selecting) text on their browser. I just want to stop them from *pasting* input into a text field to minimize user error.

Perhaps instead of using this &quot;hack&quot; you can suggest another solution to the core problem of what I&#39;m trying to solve here? I&#39;ve done less than half a dozen user tests and this has already happened twice. My audience does not have a high level of computer proficiency.



Disable pasting text into HTML form

The workflow is simple:

 1. You click inside a textarea.
 2. The text is copied to the client&#39;s clipboard.
 3. Display notice to the user.


How do you do it?


How to copy text to the client&#39;s clipboard using jQuery?

I was passed a long running legacy ruby program, which has numerous occurrences of 

    begin
      #dosomething
    rescue Exception =&gt; e
      #halt the exception&#39;s progress
    end

throughout it. 

Without tracking down every single possible exception these each could be handling (at least not immediately), I&#39;d still like to be able to shut it down at times with &lt;kbd&gt;Ctrl&lt;/kbd&gt;&lt;kbd&gt;C&lt;/kbd&gt;.

And I&#39;d like to do so in a way which only adds to the code (so I don&#39;t affect the existing behavior, or miss an otherwise caught exception in the middle of a run.)
 
[&lt;kbd&gt;Ctrl&lt;/kbd&gt;&lt;kbd&gt;C&lt;/kbd&gt; is SIGINT, or SystemExit, which appears to be equivalent to `SignalException.new(&quot;INT&quot;)` in Ruby&#39;s exception handling system. `class SignalException &lt; Exception`, which is why this problem comes up.]

The code I would like to have written would be:

    begin
      #dosomething
    rescue SignalException =&gt; e
      raise e
    rescue Exception =&gt; e
      #halt the exception&#39;s progress
    end

**EDIT: This code works, as long as you get the class of the exception you want to trap correct. That&#39;s either SystemExit, Interrupt, or IRB::Abort as below.**
