centos脚本编写

要实现ssh s202 jps查看进程状态，就需要在环境变量目录下面创建软连接：sudo ln -s /soft/jdk/bin/jps /usr/local/bin/jps
编写xcall.sh脚本
1.touch xcall.sh //创建脚本文件
2.修改脚本权限,让所有人都能执行：chmod a+x a.sh
3.将脚本文件移动到环境变量指定的目录下面：mv xcall.sh /usr/local/bin#!/bin/bash
4.接下来写xcall.sh
echo hello world
params=$@
for (( i=201 ; i <= 204 ; i = $i+1 ));do
echo =====================s$i $params ======================
ssh s$i "$params"
done
5.接下来写xsync.sh

!/bin/bash

if [[ $# -lt 1 ]]; then echo no params ;fi

p=$1

echo p=$p

dir=dirname $p

echo dir=$dir

filename=basename $p

echo filename = $filename

cd $dir
fullpath=pwd -P .

echo fullpath = $fullpath

user=whoami
for(( i = 202 ; i <= 204 ;i = $i + 1 )) ;do
echo =s$i====
rsync -lr $p ${user}@s$i:$fullpath
done ;
