从java程序运行"rsync“的link_stat错误

Question

我想从java程序中运行rsync。以下是代码：

        String cmd = "rsync -auv /rsrch1/rists/moonshot/data/foundation/FoundationMedicine/*.csv " + archive.getAbsolutePath();
        System.out.println(cmd);

        // capture stdout and stderr from running bash script
        Process p = Runtime.getRuntime().exec(cmd);
        String line;
        BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
        while ((line = in.readLine()) != null) {
            System.out.println(line);
        }
        BufferedReader err = new BufferedReader(new InputStreamReader(p.getErrorStream()));
        while ((line = err.readLine()) != null) {
            System.out.println(line);
        }
        p.waitFor();
        in.close();
        err.close();

然而，当我运行这个java程序时，我得到了一个错误：

rsync -auv /rsrch1/rists/moonshot/data/foundation/FoundationMedicine/*.csv /rsrch1/rists/moonshot/data/dev/foundation/validation/archive
sending incremental file list

sent 18 bytes  received 12 bytes  60.00 bytes/sec
total size is 0  speedup is 0.00
rsync: link_stat "/rsrch1/rists/moonshot/data/foundation/FoundationMedicine/*.csv" failed: No such file or directory (2)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1039) [sender=3.0.6]

不过，当我在服务器上直接运行准确的命令rsync -auv /rsrch1/rists/moonshot/data/foundation/FoundationMedicine/*.csv /rsrch1/rists/moonshot/data/dev/foundation/validation/archive时，它就可以正常工作了。

我不明白为什么它不适用于Java。

在我做了一些研究之后，我发现这是由命令中的"*“引起的。这是一个只有bash才能识别的通配符，我必须使用bash运行这个命令。让它与以下方面一起工作：

String[] cmd = new String[]{"/bin/bash", "rsync -auv /rsrch1/rists/moonshot/data/foundation/FoundationMedicine/*.csv " + archive.getAbsolutePath()};
