我編寫了以下腳本,如果您在 VirtualBox 上執行 Ubuntu 並使用 NetBeans,您可能會發現該腳本很有用。這些腳本甚至可以用於滿足其他 VirtualBox 需求,因為它試圖:
- 安裝應用程式 (NetBeans)。
- 測試 Ubuntu 是否正在執行來賓新增。
- 嘗試根據預設項目名稱掛載共用資料夾,該名稱通常在任何系統(主機或來賓)上都保持不變。
- 將掛載寫入
rc.local
以方便使用。 - 在使用者 bin 中建立和/或附加檔案以允許卸載資料夾。
除非您升級,否則腳本可以完美運行。在這種情況下,將完成多次安裝,並且卸載腳本將無法按預期運行,因為/etc/mtab
.
這不能透過使用umount
標誌來解決,-f -l -a -t
通常這可能會導致所有安裝都被卸載。也不是所需的解決umount -a -t vboxsf
方案/target
,因為可能不需要卸載所有共用資料夾。
我已經想出了一個解決方案,但我對 bash/腳本很陌生,不知道如何實現它。我的解決方案是測試rc.local
潛在的重複行以避免重複安裝:

有什麼指點嗎?我的目標是為Java 開發人員編寫一個超級腳本,將最需要的工具下載到任何Linux(不僅僅是Ubuntu)上,並安裝潛在的東西,如果您有現有的開發主機,則不需要重新安裝。像 Maven、Tomcat、SVN、JBoss 這樣的東西如果已經在主機系統上,則不需要特殊的來賓安裝,並且將不同的系統合併為一個系統還有更多好處;例如,Windows 可以運行 Photoshop 和 Safari 瀏覽器,但 Linux 提供更好的客製化和開箱即用的 ssh 等工具。

我不確定我是否理解...但在這裡我計算了 grep 輸出中唯一行的數量。
grep "sudo /sbin/mount.vboxsf" /etc/rc.local | sort | uniq -c | wc -l
兩個來自回顯線,兩個來自命令列。它應該總是等於四,是嗎?
