id - Enhanced User Identity

The id module provides a more readable and colorful alternative to the standard id command, showing user and group IDs along with memberships in a structured key-value format.

When to Activate

• When the user wants to view their own or another user's identity info (UID, GID).
• When a script needs to retrieve just the numeric UID or GID.
• When performing manual verification of group memberships.

Core Principles & Rules

• Readability: Automatically provides colorful output in TTY sessions.
• Script-Friendly: Use uid_ or gid_ subcommands to store results directly in variables for automation.
• Native Fallback: Reverts to standard behavior for unknown options.

Patterns & Examples

View Identity

# Show colorful identity info for the current user
x id

Check Specific User

# View identity details for 'root'
x id root

Get Numeric UID

# Output only the numeric User ID
x id uid

Checklist

• Confirm if the user is checking their own ID or another user's.
• Verify if only the numeric ID is required for a script.
