Working with latest releases of ubuntu linux shows how well bash command auto completion works. Having seen this feature once you no longer want to miss it.
Adding auto completion on CentOS 7/8
Auto completion is a feature that can be installed using a package installable by yum.
Output looks similar to this:
Installing package is straight forward
Restarting your bash (reconnect) will enable auto completion without further configuration (for applications that have registered handlers).
Installing using dnf
If you're using dnf as package manager the command is similar.
Adding auto completion on debian/ubuntu
Similar to centos this works when using debian-based systems. Just use apt and install bash-completion.
As you can see, adding auto complete is really easy. You'll no longer want to miss this.
