Shell 脚本 - Korn Shell 和 Bash shell 之间的区别

Korn Shell： Korn Shell 或 KSH 是由一个叫 David Korn 的人开发的，它试图集成其他 shell 的特性，如 C shell、Bourne Shell 等。Korn Shell 允许开发人员在需要时生成和创建新的 shell 命令。 Korn shell 是早在一年前就开发出来的，因为它比 BASH shell 更老，资源更少，计算机用户范围有限。 Korn 有各种版本，例如 pdksh、mksh、ksh93 等等。 Korn shell 中有 print 命令可以在终端中打印消息，这比 Bash Shell 中的 echo 要好。

Bash Shell： Bash 或 Bourne Again Shell 与 Unix 中的 Bourne 或 .sh 相同。 Bash shell 由 Freeware Software Software 开发，它是在 GNU 组织下编写和许可的。这就是使 Bash shell 成为公共域 shell 的原因。 Bash shell 是免费和开源的，可供计算机用户使用。 Bash shell 的一些有用功能是选项卡完成和设置提示以显示当前目录。我们可以毫无问题地在 Bash Shell 中运行其他 shell 的语法。与其他具有大量资源和功能的 shell 相比，Bash Shell 是最近开发的 shell。
