Questions about environment variables

[dddachui]

I wonder if bashly supports global variables. Use the shell command to obtain some system parameters, such as the system version marked in/etc/centos-release, and use it as global variables after being intercepted by the command. The examples I see are set strings, and the default marked in the example is string type

You have two options to implement what are describe:

Option 1: Implement it yourself, in the initialize function

# src/initialize.sh
TEST="${TEST:-$(git --version)}"

Option 2: Assign a default value using the bash $(...) syntax

# bashly.yml
environment_variables:
- name: git_version
  help: Set your Git version
  default: $(git --version)

One more thing - if you need to extract information from the system, you don't need to employ environment variables at all.

Just add a library function (bashly add lib), and set it to extract any information you want.

Use environment variables only for things that you want the user to be able to override.
