Мои псевдонимы Bash не работают

Я не уверен, почему, но мои псевдонимы Bash, похоже, не работают. Вот мой .bashrcфайл

    # v 0.0.1 - 7/03/12

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting

# expanding history to 10000 commands
export HISTSIZE=10000

# don't store repeated commands more than once
export HISCONTROL=ignoredups

# where to look for Java
export JAVA_HOME=/Library/Java/Home

# tomcat server configuration
export CATALINA_HOME=/usr/local/apache-tomcat-6.0.35

# default editor
export EDITOR=vim

if [ -f ~/.bash_aliases ]; then
   . ~/.bash_aliases
fi

Вот мой .bash_aliasesфайл

# v 0.0.1 - 7/03/12
