Cron

The software utility Cron is a time-based job scheduler in Unix-like computer operating systems. People who set up and maintain software environments use cron to schedule jobs (commands or shell scripts) to run periodically at fixed times, dates, or intervals. It typically automates system maintenance or administration—though its general-purpose nature makes it useful for things like connecting to the Internet and downloading email at regular intervals. The origin of the name cron is from the Greek word for time, χρόνος (chronos). (Ken Thompson, author of cron, has confirmed this in a private communication with Brian Kernighan.)

cron is most suitable for scheduling repetitive tasks. Scheduling one-time tasks is often more easily accomplished using the associated at utility.

Overview

Cron is driven by a crontab (cron table) file, a configuration file that specifies shell commands to run periodically on a given schedule. The crontab files are stored where the lists of jobs and other instructions to the cron daemon are kept. Users can have their own individual crontab files and often there is a system wide crontab file (usually in /etc or a subdirectory of /etc) that only system administrators can edit.

    PLAYLIST TIME:

    Lead The Parade

    by: Korn

    Lost and alone
    I'm out of the stone
    Could be this process everyday
    Nothings my own
    The dreams that I've grown
    I won't control and throw away
    I need to make the decisions
    I need to make it right
    I need to lead the parade
    Or this shit will fucking take my life
    I want to kill the decisions
    I want to make it right
    I want to pass this test
    And complete my tormented life
    This curse is my own
    It follows me home
    Its like a child that wants to play
    The thoughts in my brain
    The subconscious pain
    Makes me think why do I stay
    I need to make the decision
    I need make it right
    I need to lead the parade
    Or this shit will take my life
    I want to kill the decisions
    I want to make it right
    I want to pass this test
    And complete my tormented life
    I want to kill the decisions
    I want it to be right
    I want to pass my test
    And complete this tormented life
    Happy, everything was wonderful
    So happy, it's beautiful
    I need to make the decision
    I need to make it right
    I want to kill the decisions
    I want to make it right
    I want to pass this test
    And complete my tormented life
    I want to kill the decisions
    I want to make it right
    I want to pass this test
    And complete my tormented life
    I'm happy, I knew you'd make it right
