Which command moves or renames files?

• A. Cp
• B. Mv
• C. Mkdir
• D. Ls

Answer: (B)

Moving or renaming files is done with the mv command. It takes a source and a destination: if you provide a new name for the same directory, mv renames the file; if the destination is a directory, mv moves the file into that directory. For example, renaming a file: mv oldname.txt newname.txt. Moving a file: mv report.txt documents/. You can also use options like -i to prompt before overwriting, -v to show what’s being done, or -u to move only if the source is newer. Other commands serve different tasks: cp copies files, mkdir creates directories, and ls lists files.
