Setting Heroku config vars that contain the special character $
问题 I am trying to set a Heroku config variable that contains the special character $ but I do not know how to properly escape it. I tried encapsulating it in quotes but got the same result. Example: heroku config:set EMAIL_PASSWORD=xxxxx$xxxxxxxx => EMAIL_PASSWORD: xxxxx heroku config:set EMAIL_PASSWORD="xxxxx$xxxxxxxx" => EMAIL_PASSWORD: xxxxx 回答1: Assuming you are using Bash (which is likely if you are on Mac or Linux) you can use single quotes to escape strings with $ , or use \ : $ echo $FOO
