当一个bash脚本运行自动输入密码 [英] Automatically input a password when a bash script is run

问题描述

举例来说，如果说我有一个脚本说：

For example, say if I have a script saying:

#!/bin/bash
sudo setpci -s 00:02.0 F4.B=00

我如何把root口令到脚本，以便它接受它作为密码时，它读取并执行sudo的线（所以我不必手动输入）？

How do I put the root password into the script so that it accepts it as the password when it reads and executes the sudo line (so I don't have to type it manually)?

推荐答案

产卵的预计会话中的bash脚本是通常你是如何自动化交互提示。

Spawning an expect session within your bash script is typically how you automate interactive prompts.

例如

expect -c "
spawn sudo setpci -s 00:02.0 F4.B=00
expect -nocase \"password:\" {send \"$PASS\r\"; interact}
"

请注意，这不是在这种情况下推荐的方法，因为它是一个大安全漏洞来存储你的root密码在bash脚本。

Note that this isn't the recommended approach in this case as it is a huge security hole to store your root password in a bash script.

正确的解决办法是修改的/ etc / sudoers文件/ 不提示您为二进制的密码。

The correct solution would be to edit your /etc/sudoers/ to not prompt you for a password for that binary.

#in /etc/sudoers
neohexane ALL=(ALL) NOPASSWD : /usr/bin/setpci
