<\/a>How to Check if there exists a Process running by Name and find its Process ID (PID)?<\/h2>\nIn this article, we will discuss finding a running process PIDs by name using psutil<\/code>.<\/p>\npsutil<\/code> library can be installed by using<\/p>\npip install psutil<\/pre>\n<\/a>Determine if Process is Running or Not<\/h3>\nFollow the simple guidelines for checking if a process is running or not. They are as such<\/p>\n
\n- def findProcessIdByName(processName):<\/li>\n
- for proc in psutil. process_iter():<\/li>\n
- pinfo = proc. as_dict(attrs=[\u2018pid\u2019, \u2018name\u2019, \u2018create_time\u2019])<\/li>\n
- if processName. lower() in pinfo[\u2018name\u2019]. lower() :<\/li>\n
- except (psutil.NoSuchProcess, psutil.AccessDenied , psutil.ZombieProcess) :<\/li>\n<\/ul>\n
To check if a process is running or not we will iterate over all the running processes using psutil.process_iter()<\/code> and during iteration match the process name.<\/p>\nSo let’s see this example to check chrome process is running or not.<\/p>\n
import psutil\r\ndef checkProcessRunning(processName):\r\n # Checking if there is any running process that contains the given name processName.\r\n #Iterate over the all the running process\r\n for proc in psutil.process_iter():\r\n try:\r\n # Check if process name contains the given name string.\r\n if processName.lower() in proc.name().lower():\r\n return True\r\n except (psutil.NoSuchProcess, psutil.AccessDenied, psutil.ZombieProcess):\r\n pass\r\n return False;\r\n\r\n# Checking if any chrome process is running or not.\r\nif checkProcessRunning('chrome'):\r\n print('Yes chrome process was running')\r\nelse:\r\n print('No chrome process was running')<\/pre>\n![\"How](\"https:\/\/python-programs.com\/wp-content\/uploads\/2021\/08\/How-to-Check-if-a-Process-is-Running-or-Not.png\")
<\/p>\n
Output:<\/strong><\/p>\nNo chrome process was running<\/pre>\nAs in my system chrome instances are not running it will return False.<\/p>\n
<\/a>Finding the Process ID(PID) by Name?<\/h3>\nIn the above program, we checked any chrome instances were running or not. But in this example, we will see how to get the Process ID of a running \u2018chrome.exe\u2019 process. For that we will iterate over all the running processes and during iteration for each process whose name contains the given string, we will keep its information in a list. The following code helps you find the PID of a running process by Name.<\/p>\n
import psutil\r\ndef findProcessIdByName(processName):\r\n # Here is the list of all the PIDs of a all the running process \r\n # whose name contains the given string processName\r\n listOfProcessObjects = []\r\n #Iterating over the all the running process\r\n for proc in psutil.process_iter():\r\n try:\r\n pinfo = proc.as_dict(attrs=['pid', 'name', 'create_time'])\r\n # Checking if process name contains the given name string.\r\n if processName.lower() in pinfo['name'].lower() :\r\n listOfProcessObjects.append(pinfo)\r\n except (psutil.NoSuchProcess, psutil.AccessDenied , psutil.ZombieProcess) :\r\n pass\r\n return listOfProcessObjects;\r\n\r\n# Finding PIDs od all the running instances of process \r\n# which contains 'chrome' in it's name\r\nlistOfProcessIds = findProcessIdByName('chrome')\r\nif len(listOfProcessIds) > 0:\r\n print('Process Exists | PID and other details are')\r\n for elem in listOfProcessIds:\r\n processID = elem['pid']\r\n processName = elem['name']\r\n processCreationTime = time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(elem['create_time']))\r\n print((processID ,processName,processCreationTime ))\r\nelse :\r\n print('No Running Process found with this text')\r\n<\/pre>\n![\"Finding](\"https:\/\/python-programs.com\/wp-content\/uploads\/2021\/08\/Finding-Process-ID-by-Name.png\")
