Get Started Free →Enhanced `uptime` with structured YAML output showing uptime, users, and 1/5/15-minute load averages. **Dependency**: This is an x-cmd module. Install x-cmd first (see x-cmd skill for installation options). see x-cmd skill for installation.

> Enhanced uptime command with structured YAML output and cross-platform support.
bash# YAML format output (default) x uptime # Raw uptime command output x uptime --raw
| 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 |
| Command | Description | |---------|-------------| | x uptime | YAML format output (default) | | x uptime --yml | YAML format (explicit) | | x uptime --raw | Raw system uptime output |
bash# 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
bash# Traditional uptime output x uptime --raw # 14:32:10 up 5 days, 3:27, 2 users, load average: 0.52, 0.58, 0.59
bash# Extract uptime x uptime | awk -F': ' '/^up/{print $2}' # Get load average x uptime | awk -F': ' '/^load/{print $2}'
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:
Divide load by CPU core count:
bash# 4-core system with load 3.2 effective_load = 3.2 / 4 = 0.8 # Still has capacity

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 23 cases were attempted. The headline lift of +35 percentage points is the difference between those two pass rates over the 23 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
