zzupdate:單條命令升級 Ubuntu 18.04 LTS

zzupdate 是什麼?

我們可以只通過一條命令使用 zzupdate 工具中將 Ubuntu PC/Server 從一個版本升級到另一個版本。它是一個自由開源工具,使用它不需要任何腳本知識,因為它只需要配置文件即可運行。

工具中提供兩個默認 shell 文件。setup.sh 自動安裝、更新代碼,將腳本轉換為一個簡單的 zzupdate shell 命令。zzupdate.sh 將執行版本間的升級。

如何安裝 zzupdate?

要安裝 zzupdate,只需執行以下命令:

$ curl -s https://raw.githubusercontent.com/TurboLabIt/zzupdate/master/setup.sh | sudo sh
.

將 Ubuntu 系統從一個版本升級到另一個版本,您不需要輸入很多命令,也不需要重新啟動,只需要運行下面的 zzupdate 命令並坐下喝杯咖啡就可以了。

請注意,當您遠程升級系統時,建議您使用以下的工具來幫助您在任何斷開連接時重新連接會話。

如何配置 zzupdate(可選)

默認情況下,zzupdate 可以開箱即用,不需要配置任何東西。當然,如果您想要自己配置一些內容也是可以的。複製提供的示例配置文件 zzupdate.default.confzzupdate.conf,並在 zzupdate.conf 中配置您的首選項。

$ sudo cp /usr/local/turbolab.it/zzupdate/zzupdate.default.conf /etc/turbolab.it/zzupdate.conf

打開文件,默認配置如下。

$ sudo nano /etc/turbolab.it/zzupdate.conf

REBOOT=1
REBOOT_TIMEOUT=15
VERSION_UPGRADE=1
VERSION_UPGRADE_SILENT=0
COMPOSER_UPGRADE=1
SWITCH_PROMPT_TO_NORMAL=0
  • REBOOT=1:系統在更新完成後自動重啟
  • REBOOT_TIMEOUT=15:重啟的默認超時值
  • VERSION_UPGRADE=1:執行從一個版本到另一個版本的版本升級
  • VERSION_UPGRADE_SILENT=0:禁用自動升級
  • COMPOSER_UPGRADE=1:自動升級
  • SWITCH_PROMPT_TO_NORMAL=0:如果值為 0,將尋找相同種類的版本升級。例如您正在運行 LTS 的版本,那麼將尋找 LTS 的版本升級,而不是用於正常版本升級。如果值為 1,那麼無論您是運行 LTS 還是正常版本,都會查找最新版本

我現在正在使用 Ubuntu 17.10 ,查看一下詳細信息。
