bash script for time

Hello Friends,

How to create a script which would print time to a file every 10 seconds for an hour ?

What have you tried and what is giving you problems?

Hints: Have a look at the date and sleep commands.

How about a one liner?

Code:

#!/bin/bash

for i in {1..360};do

    echo time >> "a file"

    sleep 10

done

Note: None of the solutions is accurate.

The problem is that though the sleep is accurate, it doesn't account for the delay caused by writing the data to the file. Things like how busy the system is, memory pressure all affecting paging, which will slow things down..

Now it can be sufficient... but over an hour the time will drift by several seconds. So it depends on what you are trying to do as to how well it works.

I guess (showing :Dff) every one missed this "3 members found this post helpful."

Oh well, why to wait 1 hour when you can do it in 1 second?

Code:

for i in {0..3600..10}; do date -d "00:00 $i seconds"; done

Anyway, responses would be more helpful if you'd describe your requirements in more details. Or is it just a homework question?!?
