Mandatory arguments to long options are mandatory for short options too.

--backup[=CONTROL] make a backup of each existing destination file

like --backup but does not accept an argument


-d, --directory

create all leading components of DEST except the last, then copy SOURCE to DEST

-g, --group=GROUP

-m, --mode=MODE
set permission mode (as in chmod), instead of rwxr-xr-x

-p, --preserve-timestamps
apply access/modification times of SOURCE files to corresponding destination files

The backup suffix is ‘~’, unless set with --suffix or SIMPLE_BACKUP_SUFFIX. The version control method may be selected via the --backup option or through the VERSION_CONTROL environment variable. Here are the values:

none, off

numbered, t

existing, nil
numbered if numbered backups exist, simple otherwise

simple, never
