How can the owner of a file be changed in the Linux operating system?

In Linux, the chown command is used to change the owner of a file.

Syntax:

chown [new_owner] [file_path]

For example, to change the owner of the file example.txt to the user user1:

chown user1 example.txt

If you want to change both the owner and the group, you can specify them separated by a colon:

chown user1:group1 example.txt

Executing this command usually requires superuser (root) privileges, so sudo is often used:

sudo chown user1 example.txt
