How to export env variables from file in bash script

Question

I need to export a lot of variables like export x1=1 export x2=2

I moved all variables in file .env and tried

source .env

After it I executed

printenv

and all of this variables were absent in the list of env variables. Also I tried export $(xargs <.env) But I have commented lines in .env file and I got following messages

#': not a valid identifier

So how can I export variables from file and skip commented lines?

Answer 1

尝试命名一个类似 variables.env 的文件，然后尝试 export variables.env echo $somevariable_name
