Bash-completion enhances bash's automatic complementing Function

The first linux release was ubuntu.

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

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;
