Running shell script from java code and pass arguments
提问by Lolly
I am executing a shell script from Java program. I have implemented it using Runtime class. Below is the code I implemented
我正在从 Java 程序执行 shell 脚本。我已经使用 Runtime 类实现了它。下面是我实现的代码
final StringBuilder sb = new StringBuilder("test.sh");
sb.append("/path to/my/text file");
final Process p = Runtime.getRuntime().exec(sb.toString());
Here sb is string buffer object where I append my parameters and use it in exec method. But the problem is the parameter I pass "/path to/my/text file" is considered as 4 parameters
这里 sb 是字符串缓冲区对象，我在其中附加参数并在 exec 方法中使用它。但问题是我传递的参数“/path to/my/text file”被认为是 4 个参数
/path
to
/my/text
file
But if run in shell as test.sh "/path to/my/text file" which is taken as single parameter. How can I achieve the same using Java code, where I need to consider this path with spaces as single argument. Any please will be really appreciable.
但是如果在 shell 中作为 test.sh "/path to/my/text file" 运行，它被当作单个参数。如何使用 Java 代码实现相同的目标，我需要将此路径与空格视为单个参数。任何请都会非常可观。

Use ProcessBuilder, it's what it's designed for, to make your life easier
使用ProcessBuilder，这就是它的设计目的，让您的生活更轻松
ProcessBuilder pb = new ProcessBuilder("test.sh", "/path", "/my/text file");
Process p = pb.start();

Use this:
用这个：
final StringBuilder sb = new StringBuilder("test.sh");
sb.append(" \"/path to/my/text file\"");

To recreate the command you run in shell manually, test.sh "/path to/my/text file", you will need to include the quotes.
要重新创建您在 shell 中手动运行的命令test.sh "/path to/my/text file"，您需要包含引号。
final StringBuilder sb = new StringBuilder("test.sh");
sb.append(" \"/path to/my/text file\""); //notice escaped quotes
final Process p = Runtime.getRuntime().exec(sb.toString());

Your approach is correct you just need to add a space (" ")before parameters and escape the "/" and " "characters in the parameters
您的方法是正确的，您只需要space (" ")在参数之前添加一个并转义参数中的"/" and " "字符
