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 “VIEWSELECT 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

  1. It would be great if the developer would add a custom icon to Zeit since right now it just shows a generic icon in my launcher in Pop!_OS 20.04 LTS.

  2. First you need to do:

    $ sudo apt-get install -y software-properties-common
    

    then you ‘tutorial’ can start.

    But this will soon result in:

    E: The depot “http://ppa.launchpad.net/blaze/main/ubuntu hirsute Release” does not contain a release file.
    N: Updating from such a depot cannot be done in a safe way, so it is disabled by default.
    N: Further details on the creation of package repositories and their user configuration can be found in the manual page apt-secure (8).

    So no luck on Debian 10 which is the mother of all “ubuntu-based Linux distributions”
