YUM Autocomplete on Fedora, CentOS, Red Hat (RHEL)
This is quick tip, howto use Bash auto complete (autocomplete) with YUM (example) on Fedora, CentOS, Red Hat (RHEL).
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.
1. Install bash-completion
1.1 Change to root
su - ## OR ## sudo -i |
1.2 Install bash-completion package with YUM
yum install bash-completion |
1.3 Logout console
Then logout console or close command line and log back in.
2. Autocomplete usage
[TAB] = press tab/tabulator
2.1 YUM commands
Example 1
[root ~]$ yum in[TAB][TAB] info install [root ~]$ yum ins[TAB] ## and you get "yum install" |
Example 2
[root ~]$ yum s[TAB][TAB] search shell [root ~]$ yum se[TAB] ## and you get "yum search" |
2.2 YUM packages
Example 1
[root ~]$ yum install fire[TAB][TAB] firebird-classic.i686 firebird.i686 firecontrol.i686 firebird-devel.i686 firebird-libfbembed.i686 firehol.noarch firebird-doc.i686 firebird-superserver.i686 firewalk.i686 [root ~]$ yum install fireh[TAB] ## and you get "yum install firehol.noarch" |
Example 2
[root ~]$ yum remove ge[TAB][TAB] gedit.i686 geoclue-devel.i686 geronimo-jms.noarch gettext.i686 gegl.i686 geoclue.i686 geronimo-jta.noarch gettext-libs.i686 genisoimage.i686 GeoIP.i686 gettext-devel.i686 [root ~]$ yum remove gen[TAB] ## and you get "yum remove genisoimage.i686" |
Note: If you run this without any letter then it might take very very long time.

Nice!
I love this blog :)
Very simple tip and very useful.
Thanks for the explanation!
I already had the package installed, not sure from what, but it will only autocomplete if I am su and not my normal user. Any reason for that?
Hi Jacob,
The problem is that the yum completion uses yum -C … which uses the root cache. This same issue is also reported as bug and might be fixed later by yum developers.
So currently best and only way to use it is just change to root user and use autocomplete then.
“So currently best and only way” … that’s a provocative statement for an open source software. As I don’t find completion for my centos (centos first time user) I don’t dare to post a solution here but fixing it yourself is definitely a way and proves the statement wrong ;)
Nice one…I agree… :D
