Comment on Using GNU screen for opening multiple shells within a single shell / Handy way to keep constant SSH connections to servers from 1 single shell by hip0.
Another very helpful screen option I forgot to mention in this article is:
screen -d -RR
This instructs screen to reattach to the first in line found screen detached session, this means if you have a couple of screen sessions, like in my article example:
screen -list
There are screens on:
1549.pts-11.pcfreak (10/27/2012 09:45:59 PM) (Detached)
15691.pts-0.pcfreak (10/24/2012 02:50:07 PM) (Detached)
2 Sockets in /var/run/screen/S-hipo.
screen -D -RR will attach to 1549 in other words you don't need to do the trivial screen -list, if you know for sure on first detached session you have certain screen program running, but directly attach it.

Another very useful feature of screen is, running an interactive program from command line without explicitly starting screen first. Lets say we would like to run mc inside screen, this is done as logical with:
$ screen mc
(Twice Enter)

Christ is Risen Eastern Orthodox Resurrection Paschal Greeting in Different Languages
Hi Stan,
I guess you cannot read the writtings on the icon as it is in cyrillic.
This is not Saint Mary and Saint Peter but Adam and Eve written in cyrillic on top of the icon.
Actually in orthodoxy it is a requirement for the depicted personalities, especially saints to have
written on the names of the saint and have the Halo. If you look closely at the picture you will notice
the two Adam and Eve are missing a Halo. The only person with a Halo in the icon is Saint John the Baptist.
Best Regards

–rwo, –report-warnings-only
This option causes only warning messages to be displayed. This can be useful when rkhunter is run via cron. Other options may
be used to force other items of information to be displayed.
–sk, –skip-keypress
When the –check command option is used, after certain sections of tests, the user will be prompted to press the return key
in order to continue. This option disables that feature, and rkhunter will run until all the tests have completed.
