What is the PID in the host, of a process running inside a Docker container?
You can look at the /proc/<pid>/status file to determine the mapping between the namespace PID and the global PID. For example, if in a docker container I start several sleep 900 processes, like this: # docker run –rm -it alpine sh / # sleep 900 & / # sleep 900 & / # sleep 900 … Read more
What’s the difference between Process.fork and Process.spawn in Ruby 1.9.2
What’s the difference between Process.fork and the new Process.spawn methods in Ruby 1.9.2 Process.fork allows you to run ruby code in another process. Process.spawn allows you to run another program in another process. Basically Process.spawn is like using Process.fork and then calling exec in the forked process, except that it gives you more options. and … Read more
How can I tell if my process is running as Administrator?
Technically, if you want to see if the member is the local administrator account, then you can get the security identifier (SID) of the current user through the User property on the WindowsIdentity class, like so (the static GetCurrent method gets the current Windows user): WindowsIdentity windowsIdentity = WindowsIdentity.GetCurrent(); string sid = windowsIdentity.User.ToString(); The User … Read more
How to I get the window handle by giving the process name that is running?
You can use the Process class. Process[] processes = Process.GetProcessesByName(“someName”); foreach (Process p in processes) { IntPtr windowHandle = p.MainWindowHandle; // do something with windowHandle }
Process.Close() is not terminating created process,c#
Process.Close() isn’t meant to abort the process – it’s just meant to release your “local” view on the process, and associated resources. I think you mean Process.Kill() or Process.CloseMainWindow(). Personally I’d try to find a more graceful way of shutting it down though.
Finding open file descriptors for a process linux ( C code )?
Here’s some code I used to use, I didn’t know about /proc/self (thx Donal!), but this way is probably more generic anyway. I’ve included the required includes for all the functions at the top. #include <string.h> #include <stdio.h> #include <dirent.h> #include <fcntl.h> #include <unistd.h> #include <errno.h> #include <sys/resource.h> #ifndef FALSE #define FALSE (0) #endif #ifndef … Read more
How can I get the PID of the parent process of my application
WMI is the easier way to do this in C#. The Win32_Process class has the ParentProcessId property. Here’s an example: using System; using System.Management; // <=== Add Reference required!! using System.Diagnostics; class Program { public static void Main() { var myId = Process.GetCurrentProcess().Id; var query = string.Format(“SELECT ParentProcessId FROM Win32_Process WHERE ProcessId = {0}”, myId); … Read more
How to add a timeout to a function in Python
The principal problem with your code is the overuse of the double underscore namespace conflict prevention in a class that isn’t intended to be subclassed at all. In general, self.__foo is a code smell that should be accompanied by a comment along the lines of # This is a mixin and we don’t want arbitrary … Read more
Process.waitFor(), threads, and InputStreams
If your external process expects something on its stdin, you MUST close the getOutputStream. Otherwise you will waitFor forever. Here is the When Runtime.exec() won’t article from JavaWorld which describes different pitfalls of exec method and how to avoid them. From my experience it’s better to consume STDOUT and STDERR of child process ( until … Read more
