You can use the bash command source
to apply the settings in your .bashrc to your current bash session - source ~/.bashrc
. Try it. If it does work, but your settings aren't applied in new terminals or when logging in through ssh (or equivalent), make sure your ~/.bashrc is parsed every time you log in. Do this by adding this to your ~/.bash_profile:
if [ -f ~/.bashrc ]
This will ensure that your settings in .bashrc are applied to all types of logins.
