Shell copy file script

Shell copy script

#!/bin/bash
#获取输入参数的个数.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=1; host<3;host++));do
	echo ----------------slave$host------------------
	rsync -av $pdir/$fname $user@slave$host:$pdir
done

Just modify the number of for loops and host name in step 5
