How can you change the ownership of a file in Linux?

To change the ownership of a file in Linux, the chown command is specifically designed for this purpose. The chown command allows users to modify the user and group ownership of a specified file or directory. For example, the syntax "chown newuser:newgroup filename" changes the ownership of "filename" to "newuser" and assigns it to "newgroup." This functionality is critical in managing file permissions and ensuring that the correct users have access to the files they need.

Other commands listed serve different functions:

• The mv command is used for moving files or renaming them, not for changing ownership.
• The chmod command modifies the permissions of a file, determining who can read, write, or execute it, rather than altering the ownership.
• The rm command is for removing files or directories and has no role in ownership management.

Understanding the specific functions of these commands is essential for effective file management in a Linux environment.
