If you don’t have it installed.

<pre lang="bash">
yum install screen
apt install screen

Before you run a process, run screen, and detach.

<pre lang="bash">
# run the command
ping yahoo.com
# ctrl-a and ctrl-d to detach

To reattach, get a list of screen sessions, and attach to it.

<pre lang="bash">
screen -ls
# result is somewhat similar to below
# attach to it
screen -dr 4452.hostname

To stop, just type exit from the screen terminal.
