sleep command

On Unix-like operating systems, the sleep command is used to delay for a specified time.

This page covers the GNU/Linux version of sleep.


The sleep command pauses for a set time defined by NUMBER.

SUFFIX may be "s" for seconds (the default), "m" for minutes, "h" for hours, or "d" for days.

Some implementations require that NUMBER be an integer, but modern Linux implementations allow NUMBER to also be a floating-point value.

If more than one NUMBER is specified, sleep delays for the sum of their values.
