Python is a strong and exponentially growing programming language in the present day. There is a multiple-way to check which script is running in the background of a Linux environment. One of them is using the subprocess module in python. Subprocess is used to run new programs through Python code by creating new processes. In this article, we are going to see how to check any script is running in the background Linux using Python.
Requirement :
- Python >=2.7, >= 3.0
- pip
Installation of Subprocess :
pip install subprocess.run
We will use subprocess.checkout() methods to get all the running processes.
Syntax : subprocess.check_output(args, *, stdin=None, stderr=None, shell=False, cwd=None, encoding=None, errors=None, universal_newlines=None, timeout=None, text=None, **other_popen_kwargs)
This run command with argument and return output.
stderr=subprocess.STDOUT is used to capture standard error in the result.
Example 1 :
In the below code we will get all the py script running in the background Linux
Python3
import subprocess pytonProcess = subprocess.check_output("ps -ef | grep .py",shell=True).decode() pytonProcess = pytonProcess.split('\n') for process in pytonProcess: print(process) |
Output :
Example 2 :
In the below example we will check whether a particular script is running in background
Python3
import subprocess pytonProcess = subprocess.check_output("ps -ef | grep test.py",shell=True).decode() pytonProcess = pytonProcess.split('\n') for process in pytonProcess: print(process) |
Output :
Example 3 :
In the below code we will get all the PHP script running in background Linux.
Python3
import subprocess pytonProcess = subprocess.check_output("ps -ef | grep .php",shell=True).decode() PHPProcess = pytonProcess.split('\n') for process in PHPProcess: print(process) |
Output :
