Scheduling shutdown in linux

When you have an unlimited internet connection, you happen to download many file over internet. And you let your computer turn on for a long time. Well it’s better for you to schedule your computer to shutdown at specific time when you estimated the download would be complete. For this though I use crontab.

scheduling shutdown daily

type this in your konsole

#crontab -e

it will open up a file, fill the file with this command

0 20 * * * /sbin/shutdown -h now

after that press esc then type :wq to get back to konsole (we are using vim, so I hope you are familiar with it). At the example above, I scheduled the computer to shutdown at 20:00 (24:00 hours format). You just have to wait till 8 pm and then your computer will be shutdown automatically. There are other examples also, like this

this is an example of cron file
#run five minutes after midnight
5 0 * * * * /sbin/shutdown -h now

#run at 2.15pm on the first day of every month
15 14 * * /sbin/shutdown -h now

you can get more detailed information by typing

$ man 5 crontab

or

$ man crontab

and you can study more about the use of crontab there.
