We will not stop to discuss the reasons, why you would need to run commands this often. I believe everyone has different reasons for that in their daily jobs or even at home PCs and laptops. Watch is a Linux command that allows you to execute a command or program periodically and also shows you output on the screen.
This means that you will be able to see the program output in time. The interval can be easily changed to meet your requirements.
The above command will check your system free memory and update the results of the free command every two seconds. If you wish to hide this header, you can use the -t option. This interval is specified in seconds.Calculus 2
Here, the 'uptime' command will run and display the updated results every 2 seconds by default. In Linux, while copying files from one location to other using cp command, the progress of data is not shown, to see the progress of data being copied, you can use the watch command along with du -s command to check the disk usage in real time. If you think that the above process is too complicated to achieve, then I suggest you to go for Advance copy commandwhich shows progress of data while copying.
Sleep is often used to debug shell scripts, but it has many other useful purposes as well. For example, when combined with for or while loops, you can get pretty awesome results. If you are new to bash scripting, you can check our guide about bash loops here.
In scripts, you can use it to tell your script to run command 1, wait for 10 seconds and then run command 2. With the above loops, you can tell bash to run a command, sleep for N amount of seconds and then run the command again. You can change the echo and date commands with your own commands or script and change the sleep interval per your needs. Important : When using the above methods, it is highly recommend that you set interval long enough to give enough time of your command to finish running, before the next execution.
The samples in this tutorial are useful, but are not meant to completely replace the cron utility. It is up to you to find which one works better for you, but if we have to separate the usage of both techniques, I would say this:.

Execute functions every 10 seconds. Medium Priority. Last Modified: I would like to have this trigger every X number of seconds. Start Free Trial. View Solutions Only. Commented: Lookup the setTimeout function Author Commented: I thought I could figure it out but i can't. I want to call the following script every 10 seconds in this attached js file ie, i want the image to change every 10 seconds.
See attached code.
Chumad, where do I place the first call in th js? I placed the setTimeOut line inside the changeImage function code snippet and then defined the AdvanceShow function directly after. This way the timer gets set each time an image is changed: Will it work this way?

The setInterval method will continue calling the function until clearInterval is called, or the window is closed. Tip: To execute a function only once, after a specified number of milliseconds, use the setTimeout method. You can also refer to a "named" function; Alert "Hello" every 3 seconds milliseconds :. Display the current time the setInterval method will execute the function once every 1 second, just like a digital watch :.

Use this value with the clearInterval method to cancel the timer.Periodically your Android application might need to perform a task, such as checking a server for updates. The AlarmManager class enables the scheduling of repeated alarms that will run at set points in the future. The AlarmManager is given a PendingIntent to fire whenever an alarm is scheduled.
The first corresponds to the time since system boot and the second to UTC time. Below is a list of the different alarm type variations available. If the device is asleep, it fires when the device is next awake. It wakes up the device if it is asleep. RTC — Fires the pending intent at a specified time.
If the device is asleep, it will not be delivered until the next time the device wakes up. Deciding on the alarm to use depends on the requirements of the task at hand. Time elapsed is suitable for setting alarms that should fire based on the passage of time, for instance regularly checking a server for changes. If you want to run a task dependent on the current locale, then the real time clock will be more suitable.
Note that elapsed time is usually the better choice. If the user changes their time settings or moves to a new locale, the change might cause some unexpected behaviour in the app. If you set a specific time for an app to sync with a server, the server could be overwhelmed when all instances of the app hit at the same time. Code for this project can be found at this Git Repo. Create a new Android project. For the view, create two buttons that will start and stop the periodic operations.
Create a class that inherits from BroadcastReceiver.
Android Notes 48: How to repeat a function (Timer)
In the onReceive method, which is called when the BroadcastReceiver is receiving an Intent broadcast, we will set up the code that runs our task.
In AlarmReceiver. We then need to register the BroadcastReceiver in the manifest file.Arduino code by nature runs in an infinite loop and everything gets executed every cycle, unless you are using conditional elements and determining when to execute certain code. Any delay you add to the code within the loop will also halt the program before continuing. The framework below will allow you to specify when to run certain functions, be it every ms, 10s or 1 hour.
It will only run code when you specify.1978 motobecane mobylette 50v
The code works by first defining your functions, in the example above func1 and func2. The loop function then becomes a checker, it constantly checks the intervals on the functions and calls the functions when the millis reaches the one we specified.

Execute functions every 10 seconds
Programming the Arduino with Visual Studio May 8, Show all. Scheduling Arduino Code run every x seconds. From this we then gain: Structure to our code. All of our program is split into different functions, we know what is happening at what interval.
Run portions of code at user defined intervals. Program speed. Less delay to get the timings right and faster execution. The above code should be compatible with every version of the Arduino.

You can create multiple alarms and timers, adjust the snooze times for your alarms and record lap times using the stopwatch.
To access the Clock app, either tap the Clock icon on the Home screen, or open the App Drawer and open the Clock app from there. By default, the Clock app initially opens to the world clock. After the first time you open the Clock app, it will open to the whichever tool was open last time. To access the alarms, tap the alarm icon at the top of the screen.
To add a new alarm, tap the plus icon button at the bottom of the screen. This button can be used to add multiple alarms.How to use busybox linux
To set the time for the alarm, tap the hour on the time on the left and then tap the hour on the clock on the right. Then, tap on the minutes on the left and tap the desired minutes on the clock. You can choose minutes in five-minute increments. Notice that the deselected days do not have white circles on them. The Oxygen ringtone is selected as the default ringtone that will sound when the alarm goes off. A popup dialog box displays asking you to choose how you want to complete this action. A list of Ringtones displays on a popup dialog box.
When the alarm is on, the slider button on the right is red and sits on the right. To turn off the alarm, tap the slider button…. To turn if on again, simply tap the slider button again. When you turn on the alarm, a message briefly displays at the bottom of the screen telling you how much time is left until the alarm goes off.
To go back and edit the settings for this alarm, tap the down arrow. Note that there is no confirmation for this action. Unlike the alarm on iOS, you can adjust the snooze time for alarms on Android. You cannot set a custom snooze time for each alarm separately, but you can change the snooze time for all alarms. To do this, tap the menu button in the upper-right corner of the screen. The default snooze time is 10 minutes.
To return to the main Clock app screen, tap the back button in the upper-left corner of the screen.Android Studio - Automatically Change Activity after Few Seconds - Tutorial
When you set an alarm, you must make sure your device is not set to silent mode or Do Not Disturb. Notice on the image below the alarm clock icon on the status bar is grayed out because we have Total Silence mode on the icon to the left of the alarm clock icon.
Once you turn up the volume or adjust the settings so the alarm will sound, the alarm icon on the status bar will be white, not gray.
