Method: LinuxStat::OS.uptime

Defined in:
lib/linux_stat/os.rb

.uptime ⇒ Object

Reads /proc/uptime and returns the system uptime:

LinuxStat::OS.uptime

=> {:hour=>16, :minute=>10, :second=>11, :jiffy=>20}

Using uptime is 10x slower than using uptime_i

If the stat isn’t available, an empty hash is returned.
