How can I use the tab key to automatically complete commands like Ubuntu?

As with Ubuntu, how does one use the tab key auto-completion command? bash-completion enhances bash's auto-completion function. The first linux release was ubuntu. Later I learned how to work and switched to the release version of The RedHat series, we found that bash is used in the same way, but the bash complementing function in the redhat system is much weaker than the bash complementing function in ubuntu, later, I found that the bash-completion software was pre-installed in ubuntu.

Vim/etc/yum. repos. d/bash. repo

[DAG]
Name = DAG repo
Baseurl = http://apt.sw.be/redhat/el?releasever/en/?basearch/dag/
Gpgcheck = 0
Enabled = 1

# Yum search bash-completion
# Yum install bash-completion

The above section is added to your yum source, and then you can use the tab key;
