How to set and describe environment variables using Rails zsh
While using the Google Map API, I just wrote the API I got and pushed it on Git Hub. Then I got this email from Git Hub ... GitGuardian has detected the following Google Key exposed within your GitHub account. ** GitGuardian has detected the following Google keys published within your GitHub account: ** ** Great! I was impressed that GitHub can do such a thing. I'm not impressed, so I immediately put it in an environment variable and tried to change the description, so please share it
What are environment variables
I think it's okay to have an image such as a variable that hides things you don't want to show.
And there are many things you can set environment variables for, so try to find a good one for yourself! In my case, I use ** zsh ** to set environment variables.
zsh seems to be the self-proclaimed "strongest" shell
How to install Zsh
For beginners: Introduction of Zsh This article was very easy to understand! Please install Zsh from this article
How to set environment variables using Zsh
% vim ~/.zshrc
Open .zsher in
Then
I think the screen looks like this
Since I have already set various settings, there are many contents described, but please ignore it
** When this screen opens, please enter "i" for the time being **
At the bottom left
-- INSERT--
This is called ** insert mode ** Because you will be able to input
export Variable name you want to use='Value you want to hide' #Please be careful not to put a space in the equal
Example
export GOOGLE_MAP_API='hoge'
If you write like this, the setting is completed
The command to exit insert mode is ** esc key ** exit After exiting ** ": wq" ** when saving settings ** ": q!" ** when not saving Please end with
afterwards Reload .zshrc and enable defined environment variables
source ~/.zshrc
This completes the environment variable settings.
