24.1 sleep: Delay for a specified time

sleep pauses for an amount of time specified by the sum of the values of the command line arguments. Synopsis:

sleep number[smhd]...

Each argument is a number followed by an optional unit; the default is seconds. The units are:

`s'

seconds

`m'

minutes

`h'

hours

`d'

days

Historical implementations of sleep have required that number be an integer. However, GNU sleep accepts arbitrary floating point numbers.

The only options are `--help' and `--version'. See section 2. Common options.
