Process Hacker supports a limited number of command line options, listed below.

-settings filename

This option allows you to specify the location of Process Hacker's settings file. filename can be a relative path, in which case the current working directory at startup is used as the base.

Examples:
ProcessHacker.exe -settings settings.xml

-nosettings

Disables settings. Settings are set to their defaults at startup, and no settings are saved.

-noplugins

Disables plugins, even if the "Enable plugins" option is set.

-newinstance

Starts a new instance of Process Hacker, even if the "Allow only one instance" option is set.

-v

Forces Process Hacker's main window to be displayed at startup, even if the "Start hidden" option is enabled.

-hide

Hides Process Hacker's main window at startup, even if the "Start hidden" option is disabled.

-elevate

Prompts for elevation if Process Hacker is not started with elevated privileges.

-c -ctype objecttype -cobject object -caction action -cvalue value

Enables command mode. The status of the operation is returned in the exit status of the process.

Possible values of objecttype:

• "process". object is the process ID, and action can be "terminate", "suspend", "resume", "priority", "iopriority" or "pagepriority".
• "service". object is the service name, and action can be "start", "continue", "pause", "stop" or "delete".
• "thread". object is the thread ID, and action can be "terminate", "suspend" or "resume".

Examples:

ProcessHacker.exe -c -ctype process -cobject 1424 -caction terminate
ProcessHacker.exe -c -ctype process -cobject 5896 -caction priority -cvalue high
ProcessHacker.exe -c -ctype service -cobject Winmgmt -caction pause

-s

Enables silent mode. No error messages are displayed for command mode, -installkph and -uninstallkph.

-ras

Enters run-as-service mode. This is used internally by the Run As command.

-nokph

Disables KProcessHacker. Process Hacker will not attempt to load the driver or connect to it.

-installkph

Installs KProcessHacker as a System Start service.

-uninstallkph

Deletes the KProcessHacker service.

-debug

Shows the debug console early in the startup process.

-showoptions -hwnd parentwindow -point x,y

Displays the Advanced tab of the options window only. parentwindow specifies the parent window handle in hexadecimal and x,y specifies the location of the options window.

-phsvc

Enters phsvc mode. This exposes a LPC-based API currently used by Process Hacker for tasks that require elevation.

-priority r|h|n|l

Sets the priority of Process Hacker to realtime (r), high (h), normal (n) or idle (l).

-selectpid pid

Selects pid in a new or existing instance of Process Hacker.

-sysinfo section

Opens the System Information window at startup, and optionally navigates to the specified section.

Thanks! The "-hide" option is especially useful for peoples who want to start Process Hacker minimized at windows startup.

Sounds like a noob could do it! I will be giving it a try sometime! Wish me luck!

very helpful

It would save time if there was a command line option to start directly in "System Information/CPU/One Graph per CPU" or other "System Information/view" modes. Thank you for this very nice tool.

There are new command line actions? Like unloaddll and injectdll?

There are plugins for this

Those two options require user interaction and will not be available from the command line as they would likely become a target for malicious software.

That's what I thought but when I was going through the source code I saw theses parameters so I asked.

Is there an option to Restart a process from the command line? This is an option in the GUI.
