在程式中的函數名稱中，冒號是被許可加入的其中的元素之一。 建議修改成： |
This is not portable behavior, and therefore not a recommended practice. In fact, more recent releases of Bash do not permit this usage. An underscore _ works, though. >`這是不可移植的作法，因此不推薦這樣的行為。事實上，最近所釋出的Bash版本並不允許這種用法。但使用下劃線「_」即可運作。` A colon can serve as a placeholder in an otherwise empty function. >`在空函數之中，冒號可做為暫駐功能。`

Thanks btw，如果有做修改的話，commit 訊息應該是「中文翻譯修改」而不是「中文翻譯新增」 |
! reverse (or negate) the sense of a test or exit status [bang]. The ! operator inverts the exit status of the command to which it is applied (see Example 6-2). It also inverts the meaning of a test operator. This can, for example, change the sense of equal ( = ) to not-equal ( != ). The ! operator is a Bash keyword. >`反轉（或否定）測試或退出當前程式狀態的用途[bang]。驚嘆號用作反轉命令，以及其所施加的退出狀態（請參照範例6-2），同時驚嘆號也可反轉操作者的意圖，例如將等於（=）轉為不等於（!=）。驚嘆號是Bash中的關鍵單字。` In a different context, the ! also appears in indirect variable references. >`在不同的內文之中，驚嘆號也出現在間接變數的引用之中。` In yet another context, from the command line, the ! invokes the Bash history mechanism (see Appendix L). Note that within a script, the history mechanism is disabled. >`另一方面，在命令列中，驚嘆號調用Bash的歷史紀錄（請見 Appendix L）。請注意在腳本中，歷史紀錄是無法作用的。`
