shell脚本

1.shell脚本传参

https://blog.csdn.net/sinat_36521655/article/details/79296181

2.shell脚本获得其他命令的执行结果

http://book.51cto.com/art/201411/457601.htm

3.shell脚本读取输入

4.shell怎么修改环境变量

java通用启动脚本

#!/bin/bash

#程序住目录
APP_HOME=/usr/local/ods/app/dispatch

if [ ! -d "$APP_HOME/log4j" ]; then
  mkdir $APP_HOME/log4j
fi

#需要启动的Java主程序（main方法类）
APP_MAINCLASS=com.pa.agentbank.drs.job.Start

#java虚拟机启动参数
JAVA_OPTS="-Xms1024m -Xmx1024m -Xmn256m  -Dsys_config_path=/usr/local/ods/app/dispatch/"

#拼凑完整的classpath参数，包括指定lib目录下所有的jar
for i in "$APP_HOME"/lib/*.jar; do
   CLASSPATH="$CLASSPATH":"$i"
done

for i in "$APP_HOME"/*.jar; do
   CLASSPATH="$CLASSPATH":"$i"
done

#(函数)判断程序是否已启动

#说明：
#使用JDK自带的JPS命令及grep命令组合，准确查找pid
#jps 加 l 参数，表示显示java的完整包路径
#使用awk，分割出pid ($1部分)，及Java程序名称($2部分)

#4. 启动命令执行后，再次调用checkpid函数
#5. 如果步骤4的结果能够确认程序的pid,则打印[OK]，否则打印[Failed]

#(函数)停止程序
#
#说明：
#1. 首先调用checkpid函数，刷新$psid全局变量
#2. 如果程序已经启动（$psid不等于0），则开始执行停止，否则，提示程序未运行
#3. 使用kill -9 pid命令进行强制杀死进程
#4. 执行kill命令行紧接其后，马上查看上一句命令的返回值: $?
#5. 如果步骤4的结果$?等于0,则打印[OK]，否则打印[Failed]
#6. 为了防止java程序被启动多次，这里增加反复检查进程，反复杀死的处理（递归调用stop）。
#注意：echo -n 表示打印字符后，不换行
#注意: 在shell编程中，"$?" 表示上一句命令或者一个函数的返回值
