How to install bash completion on linux
Autocomplete feature is familiar to many who have used the Debian based Linux, like Debian and Ubuntu. For some reason, this feature is not automatically activated/installed on Red Hat -based Linux distros, like Fedora, CentOS and Red Hat (RHEL). Actually auto completion works with any Bash programs, but I think it’s very useful example with YUM and also with RPM.
Debian
apt-get install bash-completion
Centos
yum install bash-completion
