$ sudo apt update
$ sudo apt install zeit

You can also try the development version of Zeit by adding the following PPA repository.

Run Non-Periodic Commands Using at Command

Non-periodic commands allow the scheduling command to run one time. Yes, you are right. It is using the “at” command. Go to “VIEW → SELECT NONPERIODIC COMMANDS” or Press “CTRL+N”.

Choose “Add Command” as shown in the below image and add the entry. I am scheduling a command to run at 17:35. This command will create an empty log file in the Downloads folder with today’s date added to the file name as shown below.

NOW=$(date +%F); touch /home/tecmint/Downloads/log_${NOW}.txt

Now there is an entry added. You cannot modify the scheduled command but it is possible to delete the command before it runs using “Delete Command“.

At 17:35 my command ran fine and created an empty log file.

Run Periodic Tasks Using Cron Jobs

To schedule Cron jobs, choose “periodic task” or press “CTRL + P“. By default zeit will launch with “Periodic task“.

Enter a description, command, and scheduled time and press ok to add the entry to crontab.

Now my job is scheduled to run daily at 13:00.

You can check the crontab using “crontab -l” where the entry will be added automatically.

$ crontab -l

In addition to “at” and “crontab“, there is two feature to use alarm/timer which reminds us by invoking the sound. This entry will also be added to the crontab.
