What command should Shakira use to rename "untitled_essay.doc" to "draft1.doc"?

The command to rename files in a Unix-like operating system, including Linux and macOS, is mv, which stands for "move." This command is used not only to move files from one location to another but also to rename them by specifying the current name and the new name you desire.

In this case, Shakira needs to rename the file "untitled_essay.doc" to "draft1.doc." The correct command, mv untitled_essay.doc draft1.doc, takes the existing file, which is the first argument, and changes its name to the second argument. Therefore, this command accurately captures the action Shakira wants to perform—renaming the file.

The other options do not correctly execute the desired renaming operation for various reasons. Some utilize the rename command, which is not standard on all systems and may not function as intended in the context given here. Meanwhile, others have their arguments in the incorrect order for renaming tasks. The chosen command properly reflects the standard Unix command pattern needed for renaming files.
