shell 清理log ，
#/bin/bash
find /var/log/hadoop/ocdp/ -mtime +2 -name "hdfs-audit.log.*" -exec rm -rf {} \;
find . -name "*.log.*" -exec du -k {} \; |awk '{sum+=$1}END{print sum}'

ssh 登录跳转脚本，不需要每次去登录了， 直接执行./tiao.sh 就可以登录到目标主机上了。
cat tiao.sh // 跳了两次
#!/usr/bin/expect
set timeout 3
spawn ssh ocdc@xx.xx.xxx.xxx
expect "*password:"
send "23pBZHjg4y\r"
#interact
expect "]*"
send "ssh root@yy.yy.yyy.y \r"
expect "*password:"

#!/usr/bin/expect 实现自动su , 自动跳转

SSH 互信 ，脚本实现yes, 密码 输入。 脚本执行完成后，会更改 PS1 变量。 需执行 PS1='[\u@\h \w]\$ '
