Execute sh file from Java
提问by Keir Nellyer
I am trying to execute an sh file via the following code (CentOS machine btw)
我正在尝试通过以下代码执行 sh 文件（CentOS 机器顺便说一句）
Runtime.getRuntime().exec("sh " + file.getPath());
I use this code for windows and it works fine
我将此代码用于 Windows，它工作正常
Runtime.getRuntime().exec("cmd /c start " + file.getPath());
Could it be because I'm using Screen in the .sh file? I am also using the java command to start the server so maybe I need to include these?
可能是因为我在 .sh 文件中使用 Screen 吗？我也在使用 java 命令来启动服务器，所以也许我需要包含这些？
Here are the contents of the sh file
下面是sh文件的内容
#!/bin/sh
BINDIR=$(dirname "$(readlink -fn "Runtime.getRuntime().exec(new String[]{"/bin/sh" ,"-c", file.getPath()});
")")
cd "$BINDIR"
screen -S PrivateServer java -Xms2048M -Xmx2048M -jar somejar.jar -o true
I am also running this code from a shutdown hook, could this be the issue? This is intended because the software is a game server and it is intended so that the user can use a restart command or have it auto restart without needing to setup anything them self.
我也在从关闭挂钩运行此代码，这可能是问题吗？这是因为该软件是一个游戏服务器，它的目的是让用户可以使用重启命令或让它自动重启，而无需自己设置任何东西。
Edit: I decided to output the errors to a text file and found this "Must be connected to a terminal." any ideas? I believe this is an issue to do with using screen.
编辑：我决定将错误输出到一个文本文件，发现这个“必须连接到终端”。有任何想法吗？我相信这是与使用屏幕有关的问题。

Since you confirmed that the file has executable permission, try to pass the argument as follows:
由于您确认该文件具有可执行权限，请尝试按如下方式传递参数：
##代码##So mainly provide the complete path for shand use -c
所以主要提供完整的路径供sh使用-c

Yo need to set the permissions for the operation, usually the "sh" files require execution permission in order to run this scripts from a Java Application. You must run the Java application as root (sudo su) or sudo java -jar. Or set full access to your script "sudo chmod 777 ..." well, not full access, but at least chmod +x for any user that wants to execute your script.
您需要为操作设置权限，通常“sh”文件需要执行权限才能从 Java 应用程序运行此脚本。您必须以 root (sudo su) 或 sudo java -jar 身份运行 Java 应用程序。或者设置对您的脚本的完全访问权限“sudo chmod 777 ...”好吧，不是完全访问权限，但对于任何想要执行您的脚本的用户，至少 chmod +x 。
Best regards.
最好的祝福。

I recommend using org.apache.commons.exec.* to run such.
我建议使用 org.apache.commons.exec.* 来运行它。

It does not seem to have executable permissions, try executing "chmod +x shell_script_filename"before executing the shell script
好像没有可执行权限，"chmod +x shell_script_filename"在执行shell脚本前尝试执行
