These 2 days I am attending the IBM Power Linux workshop organized and sponsored by IBM itself for partners (My System Integrator is one of them i guess). Basically the instructor introduced us to the Red Hat Enterprise Linux environment and the lab hands on session consist of mainly mastering the terminal. This is also the first time I am using cron table to schedule tasks in Linux environment.

So what is a cron?
Cron is the name of program that enables unix users to execute commands or
scripts (groups of commands) automatically at a specified time/date. It is
normally used for sys admin commands, like makewhatis, which builds a
search database for the man -k command, or for running a backup script,
but can be used for anything. A common use for it today is connecting to
the internet and downloading your email.

Maybe tomorrow we will be asked to install the distribution on the server whatsoever. Here i want to share a video of IBM integration with Linux system. Enjoy!
