Where to execute bash command in visual studio?

I want to setup CI for my flutter project, and i need to encrypt the keystore file. For this i choose the following solution: https://docs.travis-ci.com/user/encrypting-files/

I am developing with visual studio code, also i have no idea about bash. I need to execute following command:

$ travis encrypt-file super_secret.txt
encrypting super_secret.txt for rkh/travis-encrypt-file-example
storing result as super_secret.txt.enc
storing secure env variables for decryption

Questions:

1. Where do I execute this command? Currently i try to use the git bash, but that does not seem to work.
2. Is this command above “one single command” or should i execute every single line seperate?
3. I assume that git bash is the wrong place, what do i need to execute this in the right environtment?

Answer

1. You execute it in your local command line – it doesn’t matter which one really, but you have to taken care of the prerequisites, meaning you installed the travis CLI and logged into your account. You also have to be in the folder of your project that already has Travis setup.
2. Only the first line is a command, the other 3 lines are output this command will generate (Commands are often prefixed with $ to indicate that this should be input on your shell / command line and executed with [Enter])
3. See 1)
