Ever faced a problem with your ssh connection dying in middle of an installation Or in middle of data transfer ? scp rsync stopping in middle due to a ” Connection Closed ” message ?
Linux has a solution for you for this very scenario. It has a utility that allows you to run any task in the background , without worrying about the connection breaking down due to internet or network cable or any other issue, its called screen. screen will keep things running for you in the background and you can again connect to the screen process and the task would be running as it is. So how do we install and use it ? . Lets start with the installation.
Installing screen :
You can check if screen binary already exist by using below command :
root@CentOS5Server [~]# which screen
/usr/bin/screen
root@CentOS5Server [~]#
If it is already available you are good to go and can move on next step of utilizing this binary/utility.
If its not installed on your machine then you can install it using simple yum command on CentOS , RHEL or any RHEL family distros. You can do it as follows :
yum install screen
