Open the .bash_profile file with your favorite editor (for instance C-x C-f in emacs and search for the file: ~/.bash_profile)
Write your aliases in the .bash_profile like:
- alias vw1=’vw click_train.vw -c -k –passes 10 –loss_function=logistic –link=logistic -f click_model.vw’
- alias vw2=’vw click_test.vw -t -i click_model.vw -p click_predictions.txt’
- alias score=’python score_vw.py click_test.vw click_predictions.txt ‘
- alias nb=’ipython notebook’
- alias py3=’source activate python3’
The first three aliases are for vowpal wabbit routines I’ve been using a lot.
The fourth one is really useful to launch Ipython Notebook.
The last one is to switch to python 3. Before that I had to create a ‘conda’ environment for python 3 with
conda create -n python3 python=3.4
- Force the .bash_profile to execute. This loads the values immediately without having to reboot. In your Terminal window, run the following command.
$ source ~/.bash_profile
- Then, enjoy your shortcuts in Terminal! Launch a notebook in python 3 with just 4 letters and 1 number!
