shell 脚本与 java 运行时不一致

Question

脚本如下

#!/bin/bash
if [ ! -s $CATALINA_HOME ]; then
echo "Error: CATALINA_HOME not set!!!"
exit -1
fi

SHUTDOWN_SCRIPT="$CATALINA_HOME/bin/shutdown.sh"
STARTUP_SCRIPT="$CATALINA_HOME/bin/startup.sh"

#execute shutdown.sh
echo "Doing Shutdown"
$SHUTDOWN_SCRIPT
sleep 5
#execute startup.sh
echo "Doing Startup"
$STARTUP_SCRIPT

exit 0

正在关机，无法启动。

并且我运行遵循代码

Runtime rn = Runtime.getRuntime();
Process proc; 
proc = rn.exec("/script/restart.sh");
proc.waitFor();

我对 .bat 文件有类似的问题，我用

修复了它

Runtime rn = Runtime.getRuntime();
Process proc; 
proc = rn.exec("cmd /c start /script/restart.bat"); 
proc.waitFor();

使用 "cmd /c start" 调用解决了我的问题。对 .sh 文件有类似的建议吗？

Answer 1

检查文件权限是否有执行权限，如果没有设置执行权限

执行 which bash 它将 return 一条 bash 的路径尝试使用示例 /bin/bash yourShell.sh 或 /bin/sh yourShell.sh in Runtime#exec 或 ProcessBuilder（推荐）

saravana@ubuntu:~$which bash /bin/bash

    String[] commmands = { "/bin/bash", "/script/restart.sh" }; // or { "/bin/sh", "/script/restart.sh" }
    Runtime.getRuntime().exec(commmands); //or
    new ProcessBuilder(commmands).start(); //Recommended
