The screen utility in Unix/linux has been replaced by the tmux utility as of Release 9. Thus, to have a persistent connection while executing system process such as installation, you will have to migrate to the new tmux utility. In this article we will show the installation of the tmux utility into a linux environment and the general use of tmux.
Installation
The tmux utility is located in the majority of OS repositories and can be retrieved using the dnf command as the root user:
[oracle@localhost test]$ su
Password:
[root@localhost test]# /usr/bin/dnf install tmux
[root@localhost bin]# /usr/bin/dnf install tmux
