mv
FilesPackage: coreutils
Moves or renames. On the same filesystem it is an instant rename, which is what makes switching a current link atomic; across two disks it is a copy followed by a delete.
What its options do in the lessons
From the same glossary the lessons render under their commands, so the two cannot disagree.
mv -i- Asks before replacing an existing file.
mv -n- Never replaces an existing file.
mv -f- Replaces the destination without asking. In an atomic replacement it is what keeps the
mva single operation: without it an interactivemvwaits for an answer nobody will give inside a script. mv -T- Treats the destination as a file rather than as a directory to move into, which avoids landing *inside* the target by accident.
