Invoking shell from java, it complaints "stty: standard input: Invalid argument"
提问by solotim
I invoke a shell command by Process class from java and it prints
我从 java 中通过 Process 类调用 shell 命令并打印
"stty: standard input: Invalid argument"
no matter whether the command is right or wrong (normal output of shell command is shown too). If I run the shell command in shell, no such error message is shown.
不管命令是对是错（shell命令的正常输出也有显示）。如果我在 shell 中运行 shell 命令，则不会显示此类错误消息。
The command is something like this: {"/bin/csh", "-c", "echo hello"}
命令是这样的： {"/bin/csh", "-c", "echo hello"}

Try using the -foption of csh to disable the reading of the .chsrc and .login files:
尝试使用-fcsh 选项禁用读取 .chsrc 和 .login 文件：
{"/bin/csh", "-cf", "echo hello"}

You are invoking the sttycommand from your .profile, or .bash_profile. You'll have to redirect its standard error to /dev/null.
您正在stty从.profile, 或调用命令.bash_profile。您必须将其标准错误重定向到/dev/null.
stty blah blah blah 2>/dev/null
stty can't deal with the pseudo-tty that Java provides in shelling out.
stty 无法处理 Java 在 shell 中提供的伪 tty。

Quoth the documentation for java.lang.Process:
引用java.lang.Process的文档：
"The methods that create processes may not work well for special processes on certain native platforms, such as native windowing processes, daemon processes, Win16/DOS processes on Microsoft Windows, or shell scripts. The created subprocess does not have its own terminal or console."
“创建进程的方法可能不适用于某些原生平台上的特殊进程，例如原生窗口进程、守护进程、Microsoft Windows 上的 Win16/DOS 进程或 shell 脚本。创建的子进程没有自己的终端或控制台.”
Perhaps you would like the java.lang.ProcessBuilder, instead.
也许您更喜欢java.lang.ProcessBuilder。
