直接给出完整的代码案例java检查shell脚本字符串内容错误并返回具体的错误信息

用 Java 检查 shell 脚本字符串内容错误并返回具体的错误信息可以使用 Runtime 类执行 shell 命令。

以下是一个简单的示例代码:

import java.io.*;

public class CheckShellScript {
    public static void main(String[] args) {
        String script = "脚本字符串";
        File file = createTempScriptFile(script);
        String[] command = {"sh", file.getAbsolutePath()};
        Process process = null;
        try {
            process = Runtime.getRuntime().exec(command);
            int exitCode = process.waitFor();
            if (exitCode != 0) {
                String errorMessage = getErrorMessage(process.getErrorStream());
                System.out.println("脚本执行错误: " + errorMessage);
            } else {
                System.out.println("脚本执行成功.");
            }
        } catch (IOException | InterruptedException e) {
            System.out.println("执行脚本时发生错误: " + e.getMessage());
        } finally {
            if (process != null) {
                process.destroy();
            }
            file.delete();
        }
    }

    private static String getErrorMessage(InputStream errorStream) throws IOException {
        try (BufferedReader reader = new BufferedReader(new InputStreamReader(errorStream))) {
            StringBuilder builder = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                builder.append(line);
                builder.append(System.lineSeparator());
            }
            return builder.toString();
        }
    }

    private static File createTempScriptFile(String script) {
        File file = null;
        try {
            file = File.createTempFile("script", ".sh");
            try (PrintWriter writer = new PrintWriter(file)) {
                writer.print(script);
            }
        } catch (IOException e) {
            System.out.println("创建临时脚本文件时发生错误: " + e.getMessage());
        }
        return file;
    }
}

该示例代码将脚本字符串写入临时文件中，然后使用 "sh" 命令执行该文件。如果脚本执行失败，则会打印错误信息。

注意：此代码仅能在Unix系统上
