How to escape $ in a travis ci encrypted environment variable?

Travis CI's user documentation has a section on how to escape secure environment variables. It seems not to work for the '$' symbol. Is there anything special that needs done for the '$' symbol?

I setup this example. In .travis.yml:

travis encrypt "FAKE_PASSWORD=H3llo\\#Worl\\$d" -a

In my script I echo the variable and get:

fake password is H3llo#Worl

It appears that $d is being replaced with nothing. How can I fix this?

The problem is when running travis encrypt the $ symbol needs to be escaped for the command as well as when the variable is used. With two backslashes \\ it only creates one backslash in the variable and $d is still expanded by bash. Using three backslashes fixes the issue.

travis encrypt "FAKE_PASSWORD=H3llo\\#Worl\\\$d" -a

\\ creates a single backslash and \$ creates a $ symbol that is not expanded by bash. When travis runs the bash command to create that variable looks like

FAKE_PASSWORD=H3llo\\#World\$d

This is what bash expects when using a $ in a variable.
