Here is a little tip that I like.
Sometimes we need to save the local.env, prod.env file or the stg.env file ... But you don't look where is the best place to backup it .. adding to git it's not a good idea because you are storing secrets is very dangerous...
exists projects like git-secrets1, but in my opinion, it's another layer of knowledge you need to dominate.
let's keep it simple:
cp .env local.env gpg --armor -c local.env # enter a password ls local.env.asc # file encrypted created
with that you have a file encrypted symmetrical and it can be stored on your:
$ git add *.asc # your git $ cp *.asc ~/Dropbox # your dropbox $ gh gist create local.env.asc # to gist
gpg -d local.env.asc # entering the password
When your coworkers saw that they will say:
what are you doing? soo old school!!
