想从Java调用linux shell命令 [英] Want to invoke a linux shell command from Java

问题描述

我试图使用重定向（>&）和管道（|）从Java代码执行一些Linux命令。如何在csh或bash中调用该命令？

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

我试图使用这个：

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

但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

请尝试

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

。

EDIT ::
我的系统上没有csh，所以我改用bash。下面为我​​工作

: 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"});
