os.shutdown: Shut down the operating system with the command `shutdown'

Description

There is a command shutdown in both Windows and Linux, and this function uses it to shut down a computer.

After the time wait has passed, R will execute shutdown -s -t 0 (for Windows) or shutdown -h now to shut down the computer.

This function is a modified version of Yihui's shutdown function from the fun package.

os.shutdown(s = 0, m = 0, h = 0)

Arguments

s

time to wait before shutting down (in seconds), added to m and h; passed to Sys.sleep

m

time to wait before shutting down (in minutes), added to s and h; passed to Sys.sleep

h

time to wait before shutting down (in hours), added to s and m; passed to Sys.sleep

Value
