yum aliases plugin
SYNOPSIS
yum [options] alias
DESCRIPTION
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
* 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 skipping over any options, and then looks up the result (in this case "UPT" is converted to "--enablerepo=updates-test-
ing"). 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 convention, 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 "recursive" 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.
EXAMPLES
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 --obsoletes
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
