java调用shell文件、远程调用shell文件并且传入参数、.sh文件执行的几种方法
linux 运行*.sh文件的方法：
在Linux系统下运行.sh文件有两种方法，比如我在root/zpy目录下有个zpy.sh文件
第一种（这种办法需要用chmod使得文件具备执行条件(x): chmod u+x zpy.sh）：
1、在任何路径下，输入该文件的绝对路径/root/zpy/zpy.sh就可执行该文件（当然要在权限允许情况下）
2、cd到zpy.sh文件的目录下，然后执行./zpy.sh
第二种（这种办法不需要文件具备可执行的权限也可运行）：
1、在该文件路径下sh加上文件名字即可，sh zpy.sh
2、在任意路径下，sh 加上文件路径及文件名称：sh /zpy/zpy.sh
java调用shell文件并且传入参数:
public static void invokeShell(){
//方法1 执行字符串命令（各个参数1234之间需要有空格）
String path="sh /root/zpy/zpy.sh 1 2 3 4";
//方法2 在单独的进程中执行指定命令和变量。
//第一个变量是sh命令，第二个变量是需要执行的脚本路径，从第三个变量开始是我们要传到脚本里的参数。
String[] path=new String[]{"sh","/root/zpy/zpy.sh","1","2","3","4"};
try{
Runtime runtime = Runtime.getRuntime();
Process pro = runtime.exec(path);
int status = pro.waitFor();
if (status != 0)
{
System.out.println("Failed to call shell's command");
}
BufferedReader br = new BufferedReader(new InputStreamReader(pro.getInputStream()));
StringBuffer strbr = new StringBuffer();
String line;
while ((line = br.readLine())!= null)
{
strbr.append(line).append("\n");
}
String result = strbr.toString();
System.out.println(result);
}
catch (IOException ec)
{
ec.printStackTrace();
}
catch (InterruptedException ex){
ex.printStackTrace();
}
}
zpy.sh 文件
根据需要调用不同的方法：
Process exec(String command)
在单独的进程中执行指定的字符串命令。
Process exec(String[] cmdarray)
在单独的进程中执行指定命令和变量。
Process exec(String[] cmdarray, String[] envp)
在指定环境的独立进程中执行指定命令和变量。
Process exec(String[] cmdarray, String[] envp, File dir)
在指定环境和工作目录的独立进程中执行指定的命令和变量。
Process exec(String command, String[] envp)
在指定环境的单独进程中执行指定的字符串命令。
Process exec(String command, String[] envp, File dir)
在有指定环境和工作目录的独立进程中执行指定的字符串命令。
调用远程的shell脚本：pom 添加jar包依赖
