在执行shell脚本简单的命令没有sudo [英] Execute single command in shell script without sudo

问题描述

我有一个使用sudo运行大多数脚本需要它一个简单的shell脚本，但是在脚本中的命令之一是家酿安装，不能使用sudo。

I have a simple shell script that is run with sudo as most of the script requires it, yet one of the commands in the script is a Homebrew install, which cannot be executed with sudo..

所以，我的问题是执行使用sudo一个shell脚本我怎么执行命令子作为当前用户，然后继续使用sudo脚本的剩余部分时。

So, my question is when executing a shell script with sudo how do I execute sub commands as the current user and then continue the remainder of the script with sudo.

提示用户输入他的密码又是不是真的实用的脚本需要很长的执行，将需要等待5-10分钟的提示。

Prompting the user to enter his password again is not really practical as the script takes really long to execute and would require waiting 5-10 min for the prompt.

推荐答案

最简单的方法是从脚本中运行通过须藤的子命令。用户ID与可以通过$ SUDO_USER获得运行（看的输出须藤ENV ）

The easiest way is to run the subcommand via sudo from within the script. The user id to run with can be obtained by $SUDO_USER (look at the output of sudo env):

sudo -u $SUDO_USER ./exec_as_normal_user.sh
