Linux shell脚本实现命令批处理和文件批量分发

mkdir -p /usr/shell/ && cd /usr/shell/

touch /usr/shell/all.sh && chmod 777 /usr/shell/all.sh

vim /usr/shell/all.sh

#!/bin/bash
echo "------start execyting the shell script------"
# awk 读取hosts文件的第一部分ip地址
hosts=$(cat /usr/shell/hosts | awk '{print $1}')
# 传递的指令（参数）
cmd=$*
# for循环读取文件
for host in  ${hosts[*]}
do
    exec="ssh $host $cmd"
    echo $exec
    if eval $exec; then
        echo 'success'
    else
        echo "fail"
    fi
done
echo "----end th executing of the shell script------"

touch /usr/shell/scp.sh && chmod 777 /usr/shell/scp.sh

cat /etc/hosts

vim /usr/shell/hosts
