x-uptime

这是x-cmd的扩展模块,为增强版uptime工具,核心功能是输出结构化YAML格式的系统运行数据,包含当前时间、运行时长、登录用户数、1/5/15分钟负载均值,也可切换为原生uptime输出。支持Linux、macOS、Windows跨平台,自动适配底层工具,适用于脚本解析系统状态、日常查看负载趋势等场景,通过命令行执行,可加参数切换输出形式。

x uptime - System Uptime and Load

Enhanced uptime command with structured YAML output and cross-platform support.


Quick Start

# YAML format output (default)
x uptime

# Raw uptime command output
x uptime --raw

Features

  • Structured YAML output: Easy to parse and read
  • Load averages: 1, 5, and 15-minute trends
  • Cross-platform: Linux, macOS, Windows (via cosmo/busybox)
  • Auto-detection: Uses native, busybox, or cosmo backends

Output Fields

Field Description Example
time Current system time 14:32:10
up System uptime 5 days, 3 hours, 27 minutes
users Logged-in users count 2 users
load Load averages (1m, 5m, 15m) 0.52, 0.58, 0.59

Commands

Command Description
x uptime YAML format output (default)
x uptime --yml YAML format (explicit)
x uptime --raw Raw system uptime output

Examples

Basic Usage

# Default YAML output
x uptime

# Output example:
# time  : 14:32:10
# up    : 5 days, 3 hours, 27 minutes
# users : 2 users
# load  : 0.52, 0.58, 0.59

Raw Output

# Traditional uptime output
x uptime --raw
# 14:32:10 up 5 days, 3:27, 2 users, load average: 0.52, 0.58, 0.59

Parsing

# Extract uptime
x uptime | awk -F': ' '/^up/{print $2}'

# Get load average
x uptime | awk -F': ' '/^load/{print $2}'

Understanding Load Averages

Load averages indicate system busyness - the average number of processes waiting for CPU or I/O.

Value Interpretation
< 1.0 System has spare capacity
≈ 1.0 System is fully utilized
> 1.0 Processes are waiting (queue forming)

The three numbers show:

  • 1 min: Short-term trend (immediate load)
  • 5 min: Medium-term trend (recent history)
  • 15 min: Long-term trend (sustained load)

Multi-Core Systems

Divide load by CPU core count:

# 4-core system with load 3.2
effective_load = 3.2 / 4 = 0.8  # Still has capacity

Platform Notes

Linux

  • Uses native uptime command
  • Full feature support

macOS

  • Uses native uptime command
  • Full feature support

Windows

  • No native uptime command
  • Automatically uses cosmo binary or busybox
