1、scp命令

for i in 1 2 3

do

    echo "$i"

    scp -r /home/lck/hadoop/hadoop-2.7.2/etc/hadoop lck@s$i:/home/lck/hadoop/hadoop2.7.2/etc/

    echo "done!"

done

2、解压命令

#!/bin/bash

for i in 1 to 5

do

    echo "s$i"

    ssh s$i "mkdir /home/lck/java"

    scp /home/lck/java/jdk.zip lck@s$i:/home/lck/java

    ssh s$i "unzip /home/lck/java/jdk.zip"

    ssh s$i "tar -zxvf /home/lck/hadoop/hadoop-2.7.2.tar.gz"

done

3、多条命令(分号隔开)：
