Java ProcessBuilder和bash [英] Java ProcessBuilder and bash

问题描述

我正在尝试使用 ProcessBuilder 从Java执行bash脚本我的代码是:

I am trying to execute a bash script from Java with ProcessBuilder my code is :

 Process createUser = buildProcess(
            "/bin/su",
            "-c",
            "\"/opt/somedir/testdir/current/bin/psql",
            "--command",
            commandForUserCreation,
            /* "'select * from users'", */
            "--dbname",
            "mydbname\"",
            "myuser"
            );

问题是我收到错误:

 /bin/su: unrecognized option '--dbname'

如果我将 echo 放在命令的第一位，它将在bash中打印正确的命令，并且如果我复制/粘贴此命令，它将起作用！

If I put echo in first place of my commands it prints correct command in bash and if I copy/paste this command it works!

请帮助我解决此问题.

推荐答案

您需要提供整个命令以作为单个参数由 su 执行.试试这个:

You need to supply the whole command to execute by su as a single argument. Try this:

 Process createUser = buildProcess(
            "/bin/su",
            "-c",
            "/opt/vmware/vpostgres/current/bin/psql --command " + commandForUserCreation + " --dbname mydbname",
            myuser
            );
