检查 root 是否在 bash 脚本中 [英] Checking if root inside bash script

问题描述

我想在运行之前检查运行脚本的用户是否是root用户.但它似乎不起作用.我目前以 root 身份登录，但我认为语法有问题.

I want to check if the user running the script is root or not before running. But it doesn't seem to work. I'm currently logged in as root, but its something wrong with the syntax I think.

if[[ $EUID -ne 0 ]];
then
 echo "Sorry, you are not root."
 exit 1
else
 echo "You are root, script will continue."
fi

推荐答案

if 和 [ 之间需要一个空格.

You need a space between if and [.
