sleep
sleep n
Causes the script to sleep for
n
seconds, or forever if no argument is
given. It may be interrupted by sending the process a SIGALRM
. The function returns the number
of seconds actually slept. On some systems, the function sleeps
till the “top of the second.” So, for instance, a sleep 1
may sleep anywhere from 0 to 1
second, depending on when in the current second you started
sleeping.
