Is it possible to assign a variable to the sleep command?

It is possible to assign a variable to the sleep command. Consider the following shell script: #!/bin/bash SLEEP_INTERVAL=”30″ CURRENT_TIME=$ (date +”%T”) echo “Time before sleep: $ {CURRENT_TIME}” echo “Sleeping for $ {SLEEP_INTERVAL} seconds” sleep $ {SLEEP_INTERVAL} CURRENT_TIME=$ (date +”%T”) echo “Time after sleep: $ {CURRENT_TIME}”

How long does the execution of the sleep command last?

The output of this example script shows that the execution lasted 30 seconds: The following example illustrates the use of the sleep command in a script that checks whether a website is online. The script stops if it successfully pings a website, and sleep introduces a 10-second delay between unsuccessful pings.
