cp 没有 -V 选项

引用:

-v, --verbose

cp -V不是备份方式吗。指定备份文件时备份文件名的命名方式。

目前 cp 的此功能貌似应该这样使用：

引用:

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

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 - never make backups (even if --backup is given)
numbered, t - make numbered backups
existing, nil - numbered if numbered backups exist, simple otherwise
simple, never - always make simple backups
