yum [options] alias
This plugin changes other commands in yum, much like the alias command
in bash. There are a couple of notable differences from shell style
aliases though. The alias command has three forms:
* alias command
* alias command result
The first form lists all current aliases with their final result, the
second form looks up a "command" and shows it's final result or an
error message. The last form creates a new alias.
Explanation of alias to final result conversion
When you type an aliased command, like "yum --disableexcludes UPT lsu"
using the default aliases, the yum-aliases plugin first takes the first
"command", by skiping over any options, and then looks up the result
(in this case "UPT" is converted to "--enablerepo=updates-tesintg"). If
there is a match, then it will replace the aliased "command" in the
argument list and try again (again skipping over any options). By con-
vention, in the default aliases list, alias "commands" that are in all
CAPS only add options so you can join together a chain of them before
any real command or aliased command.
There are two things that can alter the above, if you have the "recur-
sive" configuration option set to off then alias processing will stop
after the first alias to command substitution. Also, like in shell
aliases, if the result starts with \ then alias processing will stop.
To create a new alias command called "rm" which does the same thing as
the command "remove" use:
yum alias rm remove
To always add the --skip-broken --disableexcludes=all --obsoletes
options to the update command (but leaving the upgrade option alone),
you could use:
yum alias update \update --skip-broken --disableexcludes=all
To override the default "up" alias to use the above update command, and
never ask for confirmation, you could use:
yum alias up update -y
