# 9.4.修改 pkg-\* 文件的名字

所有的 **pkg-\*** 文件名都使用变量定义，如果需要，可以在 **Makefile** 中更改这些变量。这对于在多个 Port 之间共享相同的 **pkg-\*** 文件或当需要写入其中一个文件时特别有用。请参见 [写入 `WRKDIR` 之外的地方](https://docs.freebsd.org/en/books/porters-handbook/porting-dads/#porting-wrkdir)，了解为什么直接写入包含 **pkg-\*** 文件的目录是一个坏主意。

以下是变量名及其默认值的列表。（`PKGDIR` 默认为 `${MASTERDIR}`。）

| 变量                 | 默认值                            |
| ------------------ | ------------------------------ |
| `DESCR`            | `${PKGDIR}/pkg-descr`          |
| `PLIST`            | `${PKGDIR}/pkg-plist`          |
| `PKGINSTALL`       | `${PKGDIR}/pkg-install`        |
| `PKGPREINSTALL`    | `${PKGDIR}/pkg-pre-install`    |
| `PKGPOSTINSTALL`   | `${PKGDIR}/pkg-post-install`   |
| `PKGDEINSTALL`     | `${PKGDIR}/pkg-deinstall`      |
| `PKGPREDEINSTALL`  | `${PKGDIR}/pkg-pre-deinstall`  |
| `PKGPOSTDEINSTALL` | `${PKGDIR}/pkg-post-deinstall` |
| `PKGMESSAGE`       | `${PKGDIR}/pkg-message`        |
