Cron Jobs are automated tasks that you can create in Linux to do such things as delete cache files or run antivirus scans. You simply set when you want the task to run and then type the full command with options.

Notes:

Each user has their own crontab file including root.
Cron Jobs will have the permissions of the user they are associated with
If you accidentally simply Type crontab with no options to exit Type – Control x c together
Crontab Editing and Viewing

    Select an editor. To change later, run 'select-editor'.
    1. /bin/nano <—- easiest
    2. /usr/bin/vim.tiny
    3. /usr/bin/code
    4. /bin/ed

    Like you said, it's this sort of user-friendliness that has gift-wrapped the user space for Microsoft and Apple. ¬_¬

    ctrl + c is all that's needed to exit out of the command "crontab" without any issues. This is the "common" shortcut for non-interactive programs to exit out of them. (
    This works with everything from "apt" to "yes". There's no "ctrl+x+c"

    Honestly, I love Linux, and I wish I could use it more often but my work flow doesn't really allow for it. But it feels like the command names were made by someone who likes using super niche words to sound hipster.

    Cronjob, that doesn't sound like a tool to schedule commands, it sounds like what you'd call getting a blowjob from corn on the cob.

    I am getting a big data certificate from my local community college where we are learning python , simple stats , Big Data Integration and Processing, Big Data Modeling and Analysis. I am a cs major with some knowledge of java and c++ once I finish the cert I’m trying to see if I will be able to get a data analyst job what do you think would be good for me or my next step? I want to get into the industry while in school to get some work experience since my part time job is draining and isn’t related to my degree thank you so much !
