Hi
Last week my friend log into my laptop through the network and opens
my CD ROM. Fortunately i catch him by his face expressions.
However i try to find out the command for it. mmmm.. got it.
(Thanks for google.)
I just need to type "eject". [I'm working in Fedora ver 13 ;)]
Even no need to be the root.
OK.. Then i thought more things to give the RETURN.
ah.. Previously i red (November 8 in 2009 blog entry)
about cron jobs in Linux. But i never used it.
i wrote
#!/bin/sh
eject
in a file and save it as "eject.sh".
Make it executable.
> chmod +x eject.sh
Then wrote
* * * * * /home/kumudu/eject.sh
in another file and save it as "execute.cron".
(Note : This says the eject.sh will trigger in every minute.)
Finally i need to set this cron job
> crontab /execute.cron
:D You know what would be the result...
Unfortunately he has blocked port 22. :(
port 22: No route to host
Need to think more.....
> crontab -l : Gives current crons
> crontab -e : Can edit the current cron.
> crontab -r : Remove the current cron.
Use man crontab for more details.
Cron expression.
[min] [hour] [day of month] [month] [day of week] [program to be run]
