echo -e "YOURPASSWORD\n" | sudo -S yourcommand
回答by stonesam92
The -S switch makes sudo read the password from STDIN. This means you can do
-S 开关使 sudo 从 STDIN 读取密码。这意味着你可以做到
echo mypassword | sudo -S command
to pass the password to sudo
将密码传递给 sudo
However, the suggestions by others that do not involve passing the password as part of a command such as checking if the user is root are probably much better ideas for security reasons
但是，出于安全原因，不涉及将密码作为命令的一部分传递的其他人的建议（例如检查用户是否为 root）可能是更好的主意

You can set the sbit for your script so that it does not need sudoand runs as root (and you do not need to write your root password in the script):
您可以s为您的脚本设置位，以便它不需要sudo并以 root 身份运行（并且您不需要在脚本中写入您的 root 密码）：
sudo chmod +s myscript
回答by Lucas Holt
One option is to use the -A flag to sudo. This runs a program to ask for the password. Rather than ask, you could have a script that just spits out the password so the program can continue.
一种选择是使用 -A 标志来执行 sudo。这会运行一个程序来询问密码。与其询问，您还可以使用一个脚本来输出密码，以便程序继续运行。

# Make sure only root can run our script
if [ "$(id -u)" != "0" ]; then
echo "This script must be run as root" 1>&2
exit 1
