如何从Java调用Linux Shell命令 [英] How to invoke a Linux shell command from Java

问题描述

我正在尝试使用重定向(>&)和管道(|)从Java执行一些Linux命令. Java如何调用csh或bash命令?

I am trying to execute some Linux commands from Java using redirection (>&) and pipes (|). How can Java invoke csh or bash commands?

我试图用这个:

Process p = Runtime.getRuntime().exec("shell command");

但是它与重定向或管道不兼容.

But it's not compatible with redirections or pipes.

推荐答案

exec不在您的Shell中执行命令

exec does not execute a command in your shell

尝试

Process p = Runtime.getRuntime().exec(new String[]{"csh","-c","cat /home/narek/pk.txt"});

相反.

: 我的系统上没有csh，所以我改用bash.以下对我有用

: I don't have csh on my system so I used bash instead. The following worked for me

Process p = Runtime.getRuntime().exec(new String[]{"bash","-c","ls /home/XXX"});
