What command would you use to rename a file in Linux?

The command used to rename a file in Linux is the mv command. This command stands for "move" and is commonly used to move files or directories from one location to another. However, it can also be used to rename files within the same directory. By specifying the current name of the file followed by the new name, you effectively change the name of the file.

For example, if you have a file named "oldfile.txt" and you want to rename it to "newfile.txt", you would use the command mv oldfile.txt newfile.txt. This action does not create a copy of the file; it simply updates the filename while keeping the file's contents intact.

The other options do not serve as primary means to rename files in standard Linux usage. While rename could also perform renaming under certain conditions with specific syntax and can be a useful tool for bulk renaming, it’s less commonly used than mv. The options rn and change are not recognized commands for renaming files in Linux environments.
