Python | os.getgid() and os.setgid() method
  • Last Updated : 25 Jun, 2019

OS module in Python provides functions for interacting with the operating system. OS comes under Python’s standard utility modules. This module provides a portable way of using operating system dependent functionality.

All functions in os module raise OSError in the case of invalid or inaccessible file names and paths, or other arguments that have the correct type, but are not accepted by the operating system.

os.getgid() method in Python is used to get the real group id of the current process and os.setgid() method is used to set the real group id of the current process.

Note: os.setgid() and os.getgid() methods are available only on UNIX platforms.

os.getgid() method



Syntax: os.getgid()

Parameter: No parameter is required

Return Type: This method returns an integer value which represents the current process’s real group id.

Code #1: Use of os.getgid() method




# Python program to explain os.getgid() method 
  
# importing os module 
import os
  
# Get the group id
# of the current process
# using os.getgid() method
gid = os.getgid()
  
# Print the group ID
# of the current process
print("Group id of the current process:", gid)
Output:
Group id of the current process: 1000

Getgid method terminal output

os.setgid() method

Syntax: os.setgid(euid)



Parameter:
euid: An integer value representing new group id for the current process.

Return Type: This method does not return any value.

Code #2: Use of os.setgid() method




# Python program to explain os.setgid() method 
  
# importing os module 
import os
  
# Get the group id
# of the current process
# using os.getgid() method
gid = os.getgid()
  
# Print the real group id
# of the current process
print("Group id of the current process:", gid)
  
# Change the group id
# of the current process
# using os.setgid() method
gid = 23
os.setgid(gid)
print("Group id changed")
  
# Print the group id
# of the current process
gid = os.getgid()
print("Group id of the current process:", gid)
Output:
Group id of the current process: 0
Group id changed
Group id of the current process: 23

Setgid method terminal output
