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

$ echo "$FOO"

$ echo '$FOO'
$FOO
$ echo \$FOO
$FOO
