我正在尝试执行一个 bash 脚本,该脚本从 java 传递了 4 个参数。我可以使用以下代码完美地执行没有参数的脚本:
try
{
String command = "bash bash/testbash.sh";
Runtime run = Runtime.getRuntime();
Process pr = run.exec(command);
pr.waitFor();
BufferedReader buf = new BufferedReader(new InputStreamReader(pr.getInputStream()));
String line = "";
while ((line=buf.readLine())!=null)
{
System.out.println(line);
}
}
catch (Exception e)
{
System.out.println("Exception " + e);
e.printStackTrace();
}
}
所以我打算创建一个 String[] 来将命令和参数都传递给 Runtime.exec(),如下所示:
try
{
String[] command ={"bash bash/testbash.sh"};
Runtime run = Runtime.getRuntime();
Process pr = run.exec(command);
pr.waitFor();
BufferedReader buf = new BufferedReader(new InputStreamReader(pr.getInputStream()));
String line = "";
while ((line=buf.readLine())!=null)
{
System.out.println(line);
}
}
catch (Exception e)
{
System.out.println("Exception " + e);
e.printStackTrace();
}
}
这给了我这个错误:

这对我来说毫无意义。bash 文件显然存在,因为我只是将它与 String 命令一起使用,但是当我将相同的东西与 String[] 命令一起使用时,它不存在吗?我将如何传递带有参数的命令?
