This wont actually work, will it? I think that -t 5 will abort the script after 5 seconds, not continue, at least according to this man page for read — Brad Parks. There — Jose H. I think you're right! I thought I tried this, but I just tried it again and it works as advertised. Paul Rooney While this code snippet may be the solution, including an explanation really helps to improve the quality of your post.

Remember that you are answering the question for readers in the future, and those people might not know the reasons for your code suggestion. This answer is a code-only comment. It does not attempt to explain the code given. I feel the poster misinterpreted the question as "How do I wait for user input while simultaneously having a timeout on that user input" — Zimano.

One correct format of this command is:. If you forget to provide the m suffix on the minutes duration, you will instruct sleep to pause for five seconds and then again for twenty seconds.

So sleep will pause for 25 seconds. Many commands require you to provide parameters in a specific order, but sleep is very forgiving.

You can provide them in any order and sleep will make sense out of them. You can also provide a floating point number as a parameter. For example, 0. All of the following increasingly eccentric commands tell sleep to pause for 10 seconds. The sleep command can be used to give a pause before the execution of a command. This command would pause for 15 seconds and then give a bleep.

You can use sleep to give a pause between two commands. This command would list the files in your Documents directory, pause for five seconds and then change the current working directory to your home directory:. You can use the sleep command in shell scripts to pause execution of the script for a precise amount of time. You can also use it to rate-limit the requests a script makes to another resource.

We can parse that data by passing it through the jq utility to retrieve the title of the book. The script requires the curl and jq utilities. The requests are made to the Google web service at one second intervals.

The title of the book will appear shortly after each ISBN number is queried. The script was chosen purely to illustrate a valid use of the sleep command. If you wish to read more about the two main components of the script, refer to the curl project page and the jq on-line manual. Use Google Fonts in Word.
