In some cases alias UNIX tool can not satisfy us. For example how would make gem install use --no-rdoc and --no-ri options by default? That is why I create Alis. Alis is more flexible tool to create aliases.


Install alis ruby gem:

gem install alis

And then do:

alis install


To get help run

alis --help

You can create, remove and list aliases with appropriate commands.

To make gem install use --no-rdoc and --no-ri options just do:

alis set --alias 'gem install' --tail '--no-rdoc --no-ri'

To list you aliases do:

alis list

And the output must be something like this:

ALIAS           EXECUTE         TAIL             
gem install     gem install     --no-ri --no-rdoc

ALIAS is what you type (alias name) to execute command.

EXECUTE is what will be really executed. (if it's not specified it is the same as ALIAS)

TAIL is additional options or arguments which will be added to tail of command you typed.

This means when you run gem install gem_name next time really will be executed gem install gem_name --no-rdoc --no-ri

How does it work?

When you run alis install it creates $HOME/.alis directory and modifies your .bashrc file to include $HOME/.alis/bin to PATH variable.

When you create a new alias Alis creates executable file in $HOME/.alis/bin which handles aliases and runs original command.

To locate original command you can use alis which:

which gem
alis which gem
