IT's not hard to measure the elapsed time:
Put Perderabo's code in a script, call it usleep.sh
will give you something like this:
real is the elapsed time.
If I want a script to sleep for less than a second, would I use a decimal? In other words, if I wanted my script to sleep for 1/4 of a second, would I say, SLEEP .25 ?? (5 Replies)

usleep
usleep(3C) Standard C Library Functions usleep(3C)NAME
usleep - suspend execution for interval in microseconds
SYNOPSIS
#include <unistd.h>
int usleep(useconds_t useconds);
DESCRIPTION
The usleep() function suspends the caller from execution for the number of microseconds specified by the useconds argument. The actual sus-
pension time might be less than requested because any caught signal will terminate usleep() following execution of that signal's catching
routine. The suspension time might be longer than requested by an arbitrary amount because of the scheduling of other activity in the sys-
tem.
If the value of useconds is 0, then the call has no effect.
The use of the usleep() function has no effect on the action or blockage of any signal. In a multithreaded process, only the invoking
thread is suspended from execution.
RETURN VALUES
On completion, usleep() returns 0. There are no error retruns.
ERRORS
No errors are returned.
USAGE
The usleep() function is included for its historical usage. The nanosleep(3C) function is preferred over this function.
