Python os.seteuid() Method Example
Below are the example of seteuid() method in Python those are following.
Use of Python os.seteuid() Method
In this example , below Python code first retrieves and prints the effective user ID of the current process using os.geteuid()
. Then, it changes the effective user ID to 100 using os.seteuid()
and prints a message indicating the change.
Python3
# importing os module import os # Get the effective user ID # of the current process # using os.geteuid() method euid = os.geteuid() # Print the effective user ID # of the current process print ( "Effective user ID of the current process:" , euid) # Change effective user ID # of the current process # using os.seteuid() method euid = 100 os.seteuid(euid) print ( "Effective user ID changed" ) # Print the effective user ID # of the current process euid = os.geteuid() print ( "Effective user ID of the current process:" , euid) |
Effective user ID of the current process: 0 Effective user ID changed Effective user ID of the current process: 1000
Python | os.geteuid() and seteuid() method
All functions in the 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.geteuid()
method in Python is used to get the current process’s effective user ID while os.seteuid()
method is used to set the current process’s effective user ID.
Effective User ID
It is normally the same as a real user ID but it is changed to enable a non-privileged user to access files that can only be accessed by root. Effective user ID is used for most access checks. It is also used as the owner of the files created by the process.
Note: os.seteuid()
and os.geteuid()
methods are available only on UNIX platforms and the functionality of os.seteuid()
method is typically available only to the superuser as only the superuser can change the user ID.
A superuser is a root user or an administrative user who has all the permissions to run or execute any program in the Operating System.
