常见的解释型语言有 Shell、Python、Ruby等。 2.2 编译型语言 编译型语言在执行之前需要先进行编译,将程序直接编译成机器语言,然后直接运行即可,不需要再进行翻译。这种程序执行效率高,依赖于编译器,跨平台性要弱一点。常见的 C、C++等都是编译型语言。 三、为什么要使用 shell 脚本 1)简单性 shell 脚本可以很...

PowerShell ISE(Integrated Scripting Environment)是一个用于编写、调试和运行 PowerShell 脚本的集成开发环境。你可以在 ISE 中打开脚本并运行。 示例:通过 PowerShell ISE 打开脚本并按 F5 执行。这些额外的方式展示了如何将 PowerShell 与各种工具、服务和环境结合起来使用,无论是在本地机器上还是在云端或容器中。
Both ShellJS and Google’s zx are libraries that provide utilities for shell scripting in JavaScript. However, they have some differences. ShellJS is a portable implementation of Unix shell commands on top of the Node.js API. It provides a simple way to run shell commands with JavaScript, an...
