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

varprocessInfos=ProcessManager.GetProcessInfos();varinitProcess=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();varinitProcessCmdLine=processInfos.Select(_=>ProcessManager.GetCmdLine(_)).First();

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

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

/sbin/init

GetEnvironmentVariables

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

some_user

GetEnvironmentVariables with predicate

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

some_user

GetEnvironmentVariable by name

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

some_user

Kill (by pid)

varpid=1000;varsignal=9;//SIGKILLProcessManager.Instance.Kill(processId,signal);ProcessManager.Instance.Kill(processId,ProcessSignal.SIGKILL);

TryKill

varpid=1000000;// not existing processvarresult=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 SIGTERMProcessManager.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
