(Thanks to Manucho)This will be the final version. This app was developed many years ago using Android 2.2 SDK. Most of the APIs used are deprecated and it is increasingly difficult to maintain it, it would be easier to rewrite the entire app. Just to compile this version, I even had to bump up the minimum supported SDK.Show MoreCron Scheduler FAQWhy can't I install Cron Scheduler?The installation of Cron Scheduler may fail because of the lack of device storage, poor network connection, or the compatibility of your Android device.

In this guide, we will be diving into what is a cron job and crontab. We example what the cron is why you would want to use it. There is also a calculator you can use to generate a crontab entry.Throughout our Raspberry Pi tutorials, we use cron jobs a fair bit. Cron jobs offer a straightforward way to schedule periodic tasks.In addition, utilizing the cron can remove the need to have a program continually running and chewing up valuable processing power and RAM.There are many situations where you will need to make use of cron jobs. It is easily one of the most useful tools available on Linux systems.To make it easier to work out a valid cron job, we have included a crontab generator at the bottom of this guide.What is a Cron Job?Cron is a time-based job scheduler that forms an integral part of Unix-like operating systems such as Linux and its many derivatives.Using the cron is a popular way for periodically running things such as commands or shell scripts.Tasks scheduled through the “cron” utility are often referred to as “Cron Jobs“. You will quickly come to rely on cron jobs when dealing with Unix based systems such as Raspbian.Cron Job FormatBelow we have included two tables. The first table shows the general syntax of a cron job. The second table shows the various symbols that are utilized within a cron job and what they can be used for.The first five components of cron job define the time that you want the task to fire. Using this, you can either set a specific time, or specify an interval such as every second day, or every minute.At the end of each cron job line, you will need to specify the command that you want to be triggered when the previous components conditions are met.We will dive into the various ways you can make use of a cron job over the next couple of sections. But for now, familiarize yourself with the general setup of a cron job.Cron Job SyntaxSix essential parts make up a cron job.The first five parts make up the timing syntax of the cron job. These five parts consist of, the minute, hour, day of the month, month, and the day of the week.The final and sixth part of the syntax is the command that you want to be executed when the conditions in the timing syntax are met.*****[COMMAND]Minute(0-59)Hour(0-23)Day Of the Month(1-31)Month(1-12)Day of the week(0-6)Command to runCron Job Symbols TableThere are a few different symbols that you can make use of within a cron job.The symbol that you will likely use the most in your cron jobs is the asterisk (*). The asterisk means that

Suspension is determined by a schedule stored in an external file. You can use CRON to schedule processes “every Tuesday and Thursday at 11PM”, “once a month at midnight of the 5th day”, “every 15 minutes on March 30”, and so on. Robo-FTP includes the CronMaker scheduling utility to help you build the "crontab.txt" file that the CRON command uses for these types of schedules. Using the CRON Command - A Brief OverviewWhen scheduling task(s) with CRON, there are usually three discrete components that need to be created:1.One or more command scripts that perform the tasks you want done.2.The event schedule file used by the CRON command.3.A simple “master” script containing an infinite loop that uses the CRON command to wait for the next event and PERFORM to launch the script(s) that do the actual work.Let's suppose you create a script file named "Monday.s" that transfers files to headquarters. First, you test this script works as a stand-alone script BEFORE using it in a CRON-based scheduling loop. Next you'll use the CronMaker utility to create an event schedule file named “crontab.txt” that will be used with the CRON command. You add an event named MondayHQ that sets CALL "Monday.s" as the value of the %nextcmd variable and runs weekly on Monday at 2:00 AM. Now you make a simple master CRON loop scrip that looks something like this: :top CRON ;; wait for scheduled eventPERFORM %nextcmd;; launch the task script GOTO top;; loop to wait for next eventCRON is the first command in the loop so Robo-FTP evaluates your schedule file and determines the duration of the suspension. In this example, MondayHQ is the only event in the schedule so execution is suspended until next Monday morning. When the program awakens from the suspension, CALL "Monday.s" is the value stored
