• all environment variables,
• a filtered list of common environment variables,
• or only the PATH variable.

Usage

The utility provides several options to customize the output.

Display All Environment Variables

By default, env-list will display all environment variables:

./env-list

Common Environment Variables

Use the -simple (or -s) flag to display only common environment variables:

Display Only the PATH Variable

Use the -path (or -p) flag to display only the PATH environment variable:

./env-list -p
