shell学习笔记（六）——实战一：脚本编写

启动jar脚本

#! /bin/bash
#cd进入jar包的所在地，java -jar执行jar包
for i in hadoop01 hadoop03;
do
        echo "============$i=========="
        ssh $i "cd /root/project/offlineDW/applog/applog/;      java -jar mock-log.jar >/dev/null 2>&1 &"
done

rsync文件分发脚本

#!/bin/bash
 
#1/ 获取输入参数个数，如果没有参数，直接退出。
pcount=$#
if((pcount==0));then
echo no args;
exit;
fi
 
#2 获取文件名称
p1=$1
fname=`basename $p1`
echo fname=$fname
 
#3 获取上级目录到绝对路径
pdir=`cd -P $(dirname $p1); pwd`
echo pdir=$pdir
 
#4 获取当前用户名称
user=`whoami`
 
#5 循环
for host in hadoop01 hadoop02 hadoop03
