os - Operating System Information

The os module provides detailed information about the current operating system, including its name, architecture, release details, load averages, and more. It is essential for writing cross-platform scripts.

When to Activate

• When the user needs to identify the system architecture (e.g., x86_64, arm64).
• When checking if the environment is Linux, macOS, WSL, or Termux.
• When monitoring system load or uptime.
• When retrieving release information for software compatibility checks.

Core Principles & Rules

• Efficient Scripting: Use variables like name_, arch_, and uptime_ in scripts for high-performance data retrieval.
• Cache Control: Subcommands starting with get (e.g., getname) bypass caches for real-time detection.
• Cross-Platform Readiness: Leverage os is <type> for robust conditional logic in shell scripts.

Patterns & Examples

Basic Information

# Show OS name and architecture
x os name
x os arch

Environment Check

# Test if running in WSL (returns 0 or 1)
x os is wsl

System Performance

# Display uptime and load averages
x os uptime
x os loadavg

Checklist

• Confirm if real-time detection is required (bypassing cache).
• Verify the specific information requested (name vs release).
