In Linux OS, which command is used to rename a file from oldname.txt to newname.txt ?

Correct option is D

The correct answer is (D) mv oldname.txt newname.txt

• The **mv** (move) command is used in Linux to rename files and directories.

• When used as mv oldname.txt newname.txt, it renames the file without creating a duplicate.

• This command is efficient because it simply updates the file metadata without copying data.

• mv is used for both moving and renaming files or directories.

• Syntax: mv [source] [destination]

• Example: mv notes.txt archive/ moves notes.txt into the archive folder.

• No confirmation prompt is given by default; existing files may be overwritten unless -i (interactive) is used.

• Option A – Create: Not a valid Linux command.

• Option B – touch: Creates new empty files; cannot rename or move files.

• Option C – cp: Copies the file to a new name but keeps the original file intact.
