How to Use Screen on Linux

I’m not going to write what screen is about in this article. I just want to make a personal note for myself about this linux utility.

Starting screen :
#screen

Create a screen session :
Ctrl-a-c

Move to next screen session :
Ctrl-a-n

Move to previous screen session :
Ctrl-a-p

Detach current screen session :
Ctrl-a-d

To view current screen session :
#screen -ls
Output sample :
—————————————–
There is a screen on:
966.pts-0.helios (Detached)
1 Socket in /var/run/screen/S-root.
—————————————–

To reconnect to 966.pts-0.helios screen session :
#screen -r 966.pts-0.helios

That’s all. I hope my post can be useful to you

Change TimeZone on Centos Linux

It’s quite easy to change time zone on centos / linux os :
cp /usr/share/zoneinfo/Asia/Jakarta /etc/localtime

Change Asia/Jakarta into your location. After copying, you can run : ntpdate pool.ntp.org
to synchornize your server time with the closest public NTP server.
