可能存在中文半角问题 执行如下指令
sed -i 's/\r$//' system_monitor.sh
执行脚本（默认2.5秒）
chmod +x ./system_monitor.sh
sudo ./system_monitor.sh
sudo ./system_monitor.sh 1
执行上述指令时,每次都需要输入密码,比较麻烦,可以使用expect来输入密码
先安装 sudo apt install expect
system_expect.sh 脚本如下
#!/usr/bin/expect
spawn sudo /home/orangepi/project/system_monitor.sh
expect {
#"yes/no" {send "yes\r";exp_continue}
"password for orangepi:" {send "orangepi\n"}
}
interact
#interact会进入交互的界面
# 比如 检测 到有 password for orangepi 出现时,就send内容 此处输入密码 orangepi 和 换行,完成输入
# exp_continue即连续输入
