Process info on windows

Otherwise, when the child process exits, the system cannot clean up the process structures for the child process because the parent process still has open handles to the child process. However, the system will close these handles when the parent process terminates, so the structures related to the child process object would be cleaned up at this point.

For an example, see Creating Processes. Skip to main content. This browser is no longer supported. I tried Cygwin but it doesn't give all pids of all the running process, only are there in the proc "directory" in cygwin.

So, if there is a way please tell it to me. In PowerShell, you use the Get-Process cmdlet to get information about one or more processes running on the system. If you run the cmdlet without any parameters, it will list all processes.

You can also use the process name without extension :. By default, PowerShell will only display some of the properties on an object returned from a cmdlet like Get-Process. To see all properties and their values, pipe the output into the Select-Object cmdlet, like so:. Here, kernel mode time and user mode time for example will show as PrivilegedProcessorTime and UserProcessorTime , respectively.

If you're new to PowerShell, it should be noted that there are aliases for common cmdlets, which makes them less verbose:. If you're looking for a GUI tool for inspecting processes, then I would recommend Process Explorer , which is substantially more powerful than Task Manager, and will show you much more detailed information about processes and the system in general:.

If called in scalar context, it returns a reference to the list of PIDs. If you pass in a list of pids, the return will be the intersection of the argument list and the actual PIDs in the system. This method returns a list of anonymous hashes, each containing information on one process.

If no arguments are passed, the list represents all processes in the system. You can pass a list of process IDs, and get out a list of the attributes of all such processes that actually exist. If you call this method in scalar context, you get a reference to the list. What keys are available depends on the variant in use. You can hope to get at least the following keys for a "normal" process i.

You may find other keys available as well, depending on which operating system you're using, and which variant of Process::Info you're using. This method also optionally takes as its first argument a reference to a hash of option values. The only supported key is:. The purpose of this static method is to specify which variants of the functionality are legal to use. Unrecognized arguments are ignored, though this may change if this class becomes a subclass of Exporter.

See "BUGS" , below, for why this mess was introduced in the first place. Usually it does not need to be explicitly called by the user, since it is called implicitly when you use WinProcess::Info;.

If you require WinProcess::Info; you will have to call this method explicitly. If this method is called more than once, the second and subsequent calls will have no effect on what variants are available. The reason for this will be made clear I hope! The only time a user of this module needs to do anything different versus version 1. This can happen two ways:.

If you must load this module using require rather than use, follow the require with. This method takes as its argument a list of PIDs, and returns a hash indexed by PID and containing, for each PID, a reference to a list of all subprocesses of that process.

If those processes have subprocesses as well, you will get the sub-sub processes, and so ad infinitum, so you may well get back more hash keys than you passed process IDs.

Note that the process of finding the sub-sub processes is iterative, not recursive; so you don't get back a tree. This method works off the ParentProcessId attribute. Not all variants support this. If the variant you're using doesn't support this attribute, you get back an empty hash.

This is a convenience method which wraps GetProcInfo. It has the same calling sequence, and returns generally the same data. Unlike the data returned from Subprocesses , the data here are not flattened; so if you specify one or more process IDs as arguments, you will get back at most the number of process IDs you specified; fewer if some of the specified processes do not exist. Note well that a given process can occur more than once in the output. Also unlike Subprocesses , you will get an exception if you use this method with a variant that does not support the ParentProcessId key.

This convenience method returns the process ID of the current process, in a form appropriate to the operating system and the variant in use. But Cygwin has its own idea of what the process ID is, which may differ from Windows.
