Linux.ProcessManager

Process manager for linux. It's can retrieve processes with linux specific info (uid of owner,gid of owner, executable path ...).

Help support the project:

Sample usage

var processInfos = ProcessManager.GetProcessInfos();

var initProcess = actual.FirstOrDefault(_ => _.ProcessName == "systemd"); 
Console.WriteLine($"Name: {initProcess.ProcessName}, " +
                  $"ProcessId: {initProcess.ProcessId}, " +
                  $"Real user id: {initProcess.Ruid}, " +
                  $"Effective user id: {initProcess.Euid}, " +
                  $"User name: {initProcess.UserName}, " +
                  $"Start time: {initProcess.StartTime}, " +
                  $"Process path (exe): {initProcess.ExecutablePath}");

Name: systemd, ProcessId: 1, Real user id: 0, Effective user id: 0, User name: root, Start time: 01.03.2018, Process path (exe): /lib/systemd/systemd

Api

GetProcessInfos

ProcessInfo[] processInfos = ProcessManager.GetProcessInfos();

GetProcessInfos (for processes ids)

ProcessInfo[] processInfos = ProcessManager.GetProcessInfos(new []{1,2,3});

GetProcessInfos (with predicate)

ProcessInfo[] processInfos = ProcessManager.GetProcessInfos(_=>_.ProcessId == 1);

GetProcessInfos (with predicate and id)

ProcessInfo[] processInfos = ProcessManager.GetProcessInfos(new []{1}, _=>_.ProcessName == "init");

GetProcessInfoById

ProcessInfo[] processInfos = ProcessManager.GetProcessInfoById(1);

GetProcessIds

int[] processInfos = ProcessManager.GetProcessIds();

EnumerateProcessIds (lazy retrieve pid)

IEnumerable<int> processInfos = ProcessManager.EnumerateProcessIds();
var initProcessCmdLine = processInfos.Select(_=>ProcessManager.GetCmdLine(_)).First();

GetCmdLine (Retrieve command line of process (exe + parameters))

var initProcessCmdLines = ProcessManager.GetCmdLine(1);
Console.WriteLine(initProcessCmdLines[0]);

/sbin/init

GetEnvironmentVariables

var pid = 1000;
var envVariables = ProcessManager.Instance.GetEnvironmentVariables(processId);
Console.WriteLine(envVariables["USER"]);

some_user

GetEnvironmentVariables with predicate

var pid = 1000;
var envVariables = ProcessManager.Instance.GetEnvironmentVariables(processId, _=>_.Key == "USER");
Console.WriteLine(envVariables["USER"]);

some_user

GetEnvironmentVariable by name

var pid = 1000;
var value = ProcessManager.Instance.GetEnvironmentVariable(processId, "USER");
Console.WriteLine(value);

some_user

Kill (by pid)

var pid = 1000;
var signal = 9;//SIGKILL
ProcessManager.Instance.Kill(processId, signal);

ProcessManager.Instance.Kill(processId, ProcessSignal.SIGKILL);

TryKill

var pid = 1000000; // not existing process
var result = ProcessManager.Instance.TryKill(processId, ProcessSignal.SIGKILL);
Console.WriteLine(result);

False

Kill (by process name)

ProcessManager.Instance.Kill("some_process", "username", ProcessSignal.SIGKILL, (ex)=>Console.WriteLine(ex.Message));
ProcessManager.Instance.Kill("some_process", "username"); // signal SIGTERM
ProcessManager.Instance.Kill("some_process", 1001/*user id*/, ProcessSignal.SIGKILL, (ex)=>Console.WriteLine(ex.Message));
ProcessManager.Instance.Kill("some_process", 1001/*user id*/);// signal SIGTERM

Kill (by predicate)

ProcessManager.Instance.Kill((processInfo)=>processInfo.ProcessName == "some_process", ProcessSignal.SIGKILL, (ex)=>Console.WriteLine(ex.Message));
ProcessManager.Instance.Kill((processInfo)=>processInfo.ProcessName == "some_process");// signal SIGTERM
