jenkins shell 假设需要在 config.yaml 文件中修改键值对：

A：使用sed命令可以在shell中修改config.yaml文件中的键值对。例如，假设要将键名为"key"的键值修改为"newvalue"，可以使用以下命令：

sed -i 's/key:.*/key: newvalue/' config.yaml

该命令将会在config.yaml文件中寻找第一个以"key:"开头的行，并将其后的值替换为"newvalue"，然后保存文件。

Jenkins shell命令修改yaml文件里的字符串完整案例

A：

假设需要在 `config.yaml` 文件中修改键值对：

database:
  host: localhost
  port: 3306

我们需要在 Jenkins Pipeline 中执行 Shell 命令来实现这个目标。以下是一个修改 `host` 值的示例脚本：

#!/bin/bash

# 将 "localhost" 替换成 "db.example.com"
sed -i 's/localhost/db.example.com/g' config.yaml

解释一下脚本中的每个部分：

- `#!/bin/bash`：指定脚本使用 Bash。
- `sed` 命令：用于在文件中查找和替换文本。
- `-i` 选项：指示 sed 直接在原始文件上进行更改，而不创建任何备份文件。
- `'s/localhost/db.example.com/g'`：用 `sed` 的替换操作将 `localhost` 替换为 `db.example.com`。
- `config.yaml`：要进行更改的文件名。

此外，您还可以将脚本包装在 Jenkins Pipeline 步骤中，例如：

stage('Configure database') {
    steps {
        sh '''
            #!/bin/bash
            sed -i 's/localhost/db.example.com/g' config.yaml
        '''
    }
}

这将创建一个名为 `Configure database` 的流水线阶段，并在其中执行 Shell 命令。请注意，`sh` 步骤使用类似于上面的示例脚本的语法内联执行 Shell 命令。
