勤看文檔啊，文檔里啥都有：

通過vagrant --help我們知道了vagrant下面所有的命令：

Additional?subcommands?are?available,?but?are?either?more?advanced

可以看到如果要管理box的話，有一個box命令，那么我們繼續看box下有什么子參數：

$?vagrant?box?--help
Usage:?vagrant?box?<subcommand>?[<args>]

Available?subcommands:
?????add
?????list
?????outdated
?????remove
?????repackage
?????update

For?help?on?any?individual?subcommand?run?`vagrant?box?<subcommand>?-h`

可以看到有add參數，顯然就是用來添加box的，那我們繼續看看box add怎么用：

$?vagrant?box?add?--help
Usage:?vagrant?box?add?[options]?<name,?url,?or?path>

Options:

????-c,?--clean??????????????????????Clean?any?temporary?download?files
????-f,?--force??????????????????????Overwrite?an?existing?box?if?it?exists
????????--insecure???????????????????Do?not?validate?SSL?certificates
????????--cacert?FILE????????????????CA?certificate?for?SSL?download
????????--capath?DIR?????????????????CA?certificate?directory?for?SSL?download
????????--cert?FILE??????????????????A?client?SSL?cert,?if?needed
????????--provider?PROVIDER??????????Provider?the?box?should?satisfy
????????--box-version?VERSION????????Constrain?version?of?the?added?box

The?box?descriptor?can?be?the?name?of?a?box?on?Vagrant?Cloud,
or?a?URL,?or?a?local?.box?file,?or?a?local?.json?file?containing
the?catalog?metadata.

The?options?below?only?apply?if?you're?adding?a?box?file?directly,
and?not?using?a?Vagrant?server?or?a?box?structured?like?'user/box':

????????--checksum?CHECKSUM??????????Checksum?for?the?box
????????--checksum-type?TYPE?????????Checksum?type?(md5,?sha1,?sha256)
????????--name?BOX???????????????????Name?of?the?box
????-h,?--help???????????????????????Print?this?help

可以看到box add接受一個<name, url, or path>的參數，說明這個文件的路徑可以是一個url或者是一個本地路徑，而vagrant的box是可以被重命名的，比如同一個鏡像文件文件，可以在在vagrant的box里叫不同的名字，這個名字在你的vagrantfile里是需要定義的，這樣vagrant才能夠通過box的名字找到具體的鏡像文件。

所以最終添加本地命令的格式為：

vagrant?box?add?--name?box_name?/path/of/box/file
