In Linux systems, many administrative tasks and automation scripts depend on knowing which user is currently executing a command. This information is often used for permission handling, logging, environment configuration, and debugging unexpected behavior in multi-user systems. This tutorial provides 2 methods how to get username of current user on Linux.

Method 1 - id command

The id command is commonly used to display user and group information. By using the -un option, it returns only the username of the current user.
