dotenvx命令行总览

这里我们讨论的dotenvx命令行，是指dotenvx Rust命令行，地址为： https://github.com/linux-china/dotenvx-rs

Dotenvx命令行是我们操作.env文件的主要方式，让我们看一下标准的帮助信息：

dotenvx - encrypts your .env files, limiting their attack vector while retaining their benefits.

Usage: dotenvx [OPTIONS] [COMMAND]

  get      return a single environment variable
  set      set a single environment variable
  encrypt  convert .env file(s) to encrypted .env file(s)
  decrypt  convert encrypted .env file(s) to plain .env file(s)
  verify   Verify the signature of the encrypted .env file
  keypair  Validate and print public/private keys for .env file in current directory
  ls       print all .env files in a tree structure
  rotate   rotate keypair and re-encrypt .env file in current directory
  diff     Display keys' values between all .env files
  cloud    Dotenv cloud operations, such as registration, sync, audit etc.

有同学可能有疑问，为何不使用编辑器直接编辑.env文件呢？提供功能完备的命令行工具，意义大吗？ 考虑到目前程序员的编辑器基本上都具备AI能力，也就是你在编辑任何文件时，可能你的代码就已经去云上转了一圈，然后获得对应的AI建议。

功能完备的命令行行工具，可以方便我们更安全地管理和使用.env文件，特别是对于加密和解密操作，当然命令行也方便自动化， 如dotenvx就提供了GitHub Actions的集成。
