执行shell脚本与从Java参数 [英] Executing shell-script with parameters from java

问题描述

我一直在谷歌上搜索了一段时间，大家似乎有不同的解决方案，其中没有一个似乎是为我工作。

I have been googling for some time, and everyone seems to have a different solution, none of which appear to be working for me.

我已经试过这两个的ProcessBuilder 和运行。无论调用 .SH 文件中直接和其送入 /斌/庆典。没有运气。

I have tried both ProcessBuilder and Runtime. Both calling the .sh file directly and feeding it to /bin/bash. With no luck.

回到基础，我目前的code是如下：

Back to basics, my current code is as follows;

String cmd[] = { "~/path/to/shellscript.sh", "foo", "bar" };
Process p = Runtime.getRuntime().exec(cmd);

这是给没有这样的文件或目录的错误，尽管手动运行;

Which is giving a No such file or directory error, despite that manually running;

~/path/to/shellscript.sh foo bar

这是bash的完美作品。

Works perfectly from bash.

我需要保持〜因为这个shellscript里存在在三个不同的用户略有不同的形式。

I need to keep the ~ because this shellscript exists in slightly different forms for three different users.

推荐答案

一个选项是处理〜自己：

String homeDir = System.getenv("HOME");
String[] cmd = { homeDir + "/path/to/shellscript.sh", "foo", "bar" };
Process p = Runtime.getRuntime().exec(cmd);

另一种方法是让猛砸为您处理：

Another is to let Bash handle it for you:

String[] cmd = { "bash", "-c", "~/path/to/shellscript.sh foo bar" };
Process p = Runtime.getRuntime().exec(cmd);
