Octave Lambda Prompt (PS1)

Posted on One min read

Problem

So I had an ugly prompt, a very ugly one

./old-PS1.jpg

Solution!

I checked the glorious docs for octave and it was pretty easy, just write

  octave:1> PS1 'λ> '
  λ>

and you will be done!

But this also looks ugly! (color wise)

  octave:1> PS1 ('\[\033[01;31m\]λ>  \[\033[0m\]')
  λ>

Adds a red color to it which looks far better, check the image below ./red-lambda-PS1.png

Making the change permanent.

Now add the previous line to ~/.octaverc, and you are set!

echo "PS1 ('\[\033[01;31m\]λ>  \[\033[0m\]')" > ~/.octaverc
