推荐答案

您可以在命令行上为 gnome-terminal 提供一些选项，它应该执行什么.

You can give gnome-terminal some options on the command line what it shall execute.

gnome-terminal -e /my/fortran/program

-x 选项可为您提供大致相同的好处，但您可以将命令行拆分为单独的单词.

The -x option gives you roughly the same benefit but you can split the commandline into separate words.

-e 和 -x 都使用可选参数运行该程序，同时将程序的标准输入和输出连接到终端.这样用户可以与终端进行正确的交互.

Both -e and -x run the program with optional arguments while connecting the program`s standard input and output to the terminal. So the user can interact with the terminal properly.

示例:

gnome-terminal -x bash -c "ls; echo '<enter>'; read"

这将打开终端并运行程序" bash . bash 将获得两个参数: -c 和 ls;回声..;阅读. -c 选项使bash解析并执行下一个参数.这将调用 ls ，然后调用 echo ... ，然后调用 read ，等待返回键.

This will open the terminal and run the "program" bash. bash will get two arguments: -c and ls; echo ....; read. The -c option makes bash parsing and executing the next argument. This will call ls, then echo ... then read which waits for the return key.

在Java中，您必须将参数适当地分成这样的数组:

In Java you must split the arguments appropriately into an array like this:

String cmd[] = {"gnome-terminal", "-x", "bash", "-c", "ls; echo '<enter>'; read" };
