x nets - Enhanced Network Statistics

Enhanced netstat with data caching and structured output formats.

Quick Start

# Update/collect network data (creates cache)
x nets update

# List available tables
x nets ls

# View a specific table
x nets view internet

Features

Data Caching: Update and cache network data for faster access
Table View: View different network tables (internet, route, etc.)
Multiple Formats: TSV, CSV output for data processing
Interactive Mode: Interactive table selection
Cross-platform: Works on Linux, macOS, Windows

Commands

Command	Description
`x nets update`	Collect and cache network data
`x nets ls`	List all available tables
`x nets view <table>`	View table in interactive mode
`x nets view --tsv <table>`	View table in TSV format
`x nets view --csv <table>`	View table in CSV format

Examples

Update Data (Create Cache)

# Collect and cache all network data
x nets update

# This creates cached data in ~/.x-cmd.root/data/nets/

List Available Tables

# Show all available tables
x nets ls

# Common tables:
# - internet  : TCP/UDP connections
# - route     : Routing table
# - interface : Network interface statistics

View Tables

# Interactive mode - select table to view
x nets view

# View specific table (interactive)
x nets view internet

# View in TSV format (for scripting)
x nets view --tsv internet

# View in CSV format
x nets view --csv route

Data Processing

# Filter connections with awk
x nets view --tsv internet | awk -F'\t' '$1 == "TCP"'

# Count connections by state
x nets view --tsv internet | cut -f4 | sort | uniq -c

# Import into spreadsheet
x nets view --csv route > route.csv

Available Tables

Table	Description
`internet`	TCP/UDP connections (like netstat)
`route`	Routing table information
`interface`	Network interface statistics

Table Output Fields

internet table

Field	Description
Protocol	TCP/UDP
Local Address	Local IP:port
Foreign Address	Remote IP:port
State	Connection state (ESTABLISHED, LISTEN, etc.)

route table

Field	Description
Destination	Target network
Gateway	Next hop
Flags	Route flags
Interface	Network interface

Workflow

# 1. Update data (do this first or when data is stale)
x nets update

# 2. List available tables
x nets ls

# 3. View specific table
x nets view internet

# 4. Or process with other tools
x nets view --tsv internet | x csv sql "SELECT * WHERE State = 'ESTABLISHED'"

Platform Notes

Linux: Uses netstat, ss, or /proc/net data
macOS: Uses netstat and route commands
Windows: Uses netstat command

Data is cached in ~/.x-cmd.root/data/nets/latest/ for faster access.
