如何获取linux终端名称

Question

我想在linux中的终端上执行一个命令。现在，为了做到这一点，我不能像windows那样对cmd进行硬编码。如何以编程方式从java中获取字符串形式的终端名称？

new ProcessBuilder(new String[] {"xfce4-terminal", "--title="+windowTitle, "--hold", "-x", "java", "-jar", decodedPath, "run"}).start();

注意字符串"xfce4-terminal“。这取决于他们所使用的linux发行版。有什么可靠的方法可以获得java命令的终端exe。在我看来，它应该是System.getProperty("os.terminal")，但是，这并不存在。

这里是确定os终端的跨平台方式。支持windows、mac和linux

    public static String osName = System.getProperty("os.name");
    public static String[] windows_terminals = new String[]
    {
        "cmd",
        "powershell",//seems to freak out and seems to be beta even in 2020 with all it's bugs
    };
    
    public static String[] mac_terminals = new String[]
    {
        "bin/bash"  
    };
    
    public static String[] linux_terminals = new String[]
    {
            "/usr/bin/gcm-calibrate",
            "/usr/bin/gnome-terminal",
            "/usr/bin/mosh-client",
            "/usr/bin/mosh-server",
            "/usr/bin/mrxvt",           
            "/usr/bin/mrxvt-full",        
            "/usr/bin/roxterm",          
            "/usr/bin/rxvt-unicode",        
            "/usr/bin/urxvt",

    };
    
    public static String getTerminal()
    {
        String[] cmds = getTerminals(osName);
        for(String cmd : cmds)
        {
            try 
            {
                Runtime.getRuntime().exec(cmd + " cd " + System.getProperty("user.dir"));
                return cmd;
            } 
            catch (Throwable e) {}
        }
        return null;
    }

    public static String[] getTerminals(String os)
    {
        return os.contains("windows") ? windows_terminals : os.contains("mac") ? mac_terminals : os.contains("linux") ? linux_terminals : null;
    }
