mv [options] source... directory
Options:
[-bfiuv] [-S backup-suffix] [-V {numbered,existing,simple}] [--backup] [--force] [--interactive] [--update] [--verbose] [--suffix=backup-suffix] [--version-control={numbered,existing,simple}] [--help] [--version]
If a destination file is unwritable, the standard input is a tty, and the -f or --force option is not given, mv prompts the user for whether to overwrite the file. If the response does not begin with `y' or `Y', the file is skipped.
"-b, --backup" Make backups of files that are about to be removed.
"-f, --force" Remove existing destination files and never prompt the user.
"-i, --interactive" Prompt whether to overwrite each destination file that already exists. If the response does not begin with `y' or `Y', the file is skipped.
"-u, --update" Do not move a nondirectory that has an existing destination with the same or newer modification time.
"-v, --verbose" Print the name of each file before moving it.
"--help" Print a usage message on standard output and exit successfully.
"--version" Print version information on standard output then exit successfully.
"-S, --suffix backup-suffix" The suffix used for making simple backup files can be set with the SIMPLE_BACKUP_SUFFIX environment variable, which can be overridden by this option. If neither of those is given, the default is `~', as it is in Emacs.
"-V, --version-control {numbered,existing,simple}" The type of backups made can be set with the VERSION_CONTROL environment variable, which can be overridden by this option. If VERSION_CONTROL is not set and this option is not given, the default backup type is `existing'. The value of the VERSION_CONTROL environment variable and the argument to this option are like the GNU Emacs `version-control' variable; they also recognize synonyms that are more descriptive. The valid values are (unique abbreviations are accepted):
`t' or `numbered' Always make numbered backups.
`nil' or `existing' Make numbered backups of files that already have them, simple backups of the others.
`never' or `simple' Always make simple backups.
