在使用sudo命令時如何不用輸入密碼或減少輸入的次數？
方法1、sudo ./script.sh
但要輸入第一次的密碼
方法2、
echo password|sudo -S apt-get update-S的意思是，講密碼從standard input中讀入
特別適合用於腳本。比如服務器的定期更新，當然你也可以直接用sudo用戶，不過不安全
方法3、
In new /etc/sudoers.d/apt-get file, put single line:user ALL=(ALL:ALL) NOPASSWD:/usr/bin/apt-get update
Fully qualified path to executable is required here.
Then use following in your script:
sudo apt-get update
Here, fully specified name is not required. Sudo uses PATH environment variable for executable resolution.
While changing and checking sudoers configuration, be sure to keep another root session open for error recovery.
