OED Tolls: Linux "at"
Another post on Linux commands, short and simple but very useful: at.
As IT pros we are all comfortable with the change window concept.
This window usually opens at night or during the week-end and sometimes the change actually just requires a few commands on a Linux machine.
The at command allows to schedule a command or script to be run at a specific time.
Usually I use it to run Python scripts with notifications on my mobile (more on that on another post) before and after so I know:
- the script has run
- the commands were executed
- the output was expected
A simple alarm clock in the night for a quick check of the notifications, if everything was right my change window lasts just a few minutes.
Sleep well ;-)
