利用shell脚本实现对系统的自动分区

#!/bin/bash
 
function print {
if [ $# = 2 ]; then
        if [ "$1" = "warning" ]; then
                echo -e "33[33m33[5m$233[0m"
        elif [ "$1" = "error" ]; then
                echo -e "33[31m33[5m$233[0m"
        elif [ "$1" = "notice" ]; then
                echo -e "33[36m33[5m$233[0m"
        fi
                echo $2
   elif [ $# = 1 ]; then
                echo -e "33[32m33[5m$133[0m"
                echo $1
 fi
  return
