uptime

Overview ¶

Package uptime implements the uptime builtin command.

uptime — tell how long the system has been running

Usage: uptime [-ps] [--help]

With no options, print the current time, how long the system has been running, and the system load averages for the past 1, 5, and 15 minutes. User count is intentionally omitted (reading utmp would expose session information).

Options:

-p, --pretty  show uptime in pretty format
-s, --since   system up since (YYYY-MM-DD HH:MM:SS)
-h, --help    display this help and exit

Data sources (platform-specific, bypass AllowedPaths — see AGENTS.md):

Linux:   /proc/uptime, /proc/loadavg
Darwin:  sysctl kern.boottime, sysctl vm.loadavg
Windows: GetTickCount64 (no load average available)

Exit codes:

0  Success
1  Error — platform not supported, kernel read failure, or invalid flag
