sleep is used to pause for a specified number of seconds, sleep is used to pause for a specified number of seconds.
It comes in 3 versions:
- small: takes one integer parameter
- fancy: takes multiple integer arguments with suffixes:
sleep 1d 2h 3m 15s
- fancy with fractional numbers:
sleep 2.3s 4.5h sleeps for 16202.3 seconds
Last one is "the most compatible" with coreutils sleep,
but it adds around 1k of code.
