How to get pid python

How to get PID by command line in python (windows)?

For that, I have planned to get PID of running django server by command line and kill it at night. Question: Using , I can get the command line.

How to get PID by command line in python (windows)?

Using psutil.Process(PID) , I can get the command line.

>>> import psutil >>> p = psutil.Process(4510) >>> p.cmdline() ['python', 'manage.py', 'runserver', '8081'] 

But, I want to know PID for a given command line.

>>> cmd = "python manage.py runserver 8081" >>> p = psutil.some_method_which_takes_command_line(cmd) >>> p.pid() 4510 

What I trying to achieve from this is, restart the django server everyday at night. For that, I have planned to get PID of running django server by command line and **** it at night. After that I will run same command cmd again to start server.

You’re probably looking for this:

import time # only here for sleep, you don't need it import subprocess cmd = ['python', 'manage.py', 'runserver', '8081'] p = subprocess.Popen(cmd) # something happens for a while here time.sleep(1) p.terminate() # or p.****() if you're on Linux and want to ****, not terminate the process 

The question specifically asked about getting the PID from the process however, that can be done as well:

import subprocess cmd = ['python', 'manage.py', 'runserver', '8081'] p = subprocess.Popen(cmd) pid = p.pid 

Be careful about obtaining a PID and just reusing it to **** a process later though, there’s often better ways to go about getting rid of a process that needs removal or restarting.

Note that if you started the process with shell=True , the PID will be the pid of the shell process, not the program started in the shell. Refer to the documentation here https://docs.python.org/3.7/library/subprocess.html

How do I get a PID from a window title in windows OS, The GetWindowThreadProcessId function seems to do what you want for getting a PID from a HWND.

How to get list of PID for all the running process with python code? [duplicate]

I am working on a project which needs the list of PID of all the running process. I want it via python programming language. How to get it? Thanks in adv.

If you are on Linux just use subprocess.Popen to spawn the ps — ef command, and then fetch the second column from it. Below is the example.

import subprocess as sb proc_list = sb.Popen("ps -ef | awk ' ' ", stdout=sb.PIPE).communicate()[0].splitlines() for pid in proc_list: print(pid) 

If you want to keep it platform independent use psutil.pids() and then iterate over the pids. You can read more about it here, it has bunch of examples which demonstrates what you are probably trying to achieve.

Please execuse any typo if any, i am just posting this from mobile device.

If you want a dictionary with pid and process name, you could use the following code:

Python | os.getpid() method, OS comes under Python’s standard utility modules. This module provides a portable way of using operating system dependent functionality. os.getpid () method in Python is used to get the process ID of the current process. Syntax: os.getpid () Parameter: Not required. Return Type: This method returns a …

Finding the command for a specific PID in Linux from Python

I’d like to know if it’s possible to find out the «command» that a PID is set to. When I say command, I mean what you see in the last column when you run the command «top» in a linux shell. I’d like to get this information from Python somehow when I have a specific PID.

Any help would be great. Thanks.

Using a /proc files has a disadvantage of lower portability, which may or may not be a concern. Here’s how you can use the standard shell command for that

Note the two -w options that instructs ps to not truncate the output (which it does by default)

Reading its output from python is as simple as calling a single function subprocess.check_output() documented here.

Look in /proc/$PID/cmdline

An interesting Python package is psutil.

For example, to get the command for a specific PID:

import psutil pid = 1234 # The pid whose info you're looking for p = psutil.Process(pid) print(p.cmdline()) 

The last line will print something like [‘/usr/bin/python’, ‘main.py’] .

A more robust way to get this information, being careful if the pid represents a process no longer running:

import psutil pid = 1234 # The pid whose info you're looking for if pid in psutil.get_pid_list(): p = psutil.Process(pid) print(p.cmdline()) 

Read up on the ps command and parse its output.

How to determine pid of process started via os.system

I want to start several subprocesses with a programm, i.e. a module foo.py starts several instances of bar.py .

Since I sometimes have to terminate the process manually, I need the process id to perform a **** command.

Even though the whole setup is pretty “dirty”, is there a good pythonic way to obtain a process’ pid , if the process is started via os.system ?

import os import time os.system("python bar.py \"\ &".format(str(argument))) time.sleep(3) pid = . os.system("kill -9 ".format(pid)) 

import time print("bla") time.sleep(10) % within this time, the process should be killed print("blubb") 

os.system return exit code. It does not provide pid of the child process.

import subprocess import time argument = '. ' proc = subprocess.Popen(['python', 'bar.py', argument], shell=True) time.sleep(3) #  

exec_cmd = 'nohup ./FPEXE & echo $! > /tmp/pid' os.system(exec_cmd)
