I am trying to create a command line interface for my website, I need to decide whether I should ask user to enter his details in a command line (Which makes it one field at a time) or should I pop up a normal form which can show everything at once.
Which is a better approach?
If the site is for developers or those who are familiar with command line, you can use one, but usually not so much people love the restricted feeling of a command line. You can use a form, and chunk it in category(e.g. Personal details, skills, experience, etc.) For pop-up form, I think is not great because is used as a dark pattern, and usually is not thinked for the benefit of the user.
As a UX designer, you are advocating for the user. :) (And sometimes you are the user).
If you want the user to fill one Input at a time then you shouldn't have more than 5 Inputs to fill. Always show at each input what is the current user location (Progress e.g 80% completed)
If you have more than 5 input fields then display the form in an overlay as users might lose interest in Single Input at a time form method if you have too many fields to fill
One other problem which comes with filling those forms, how will you handle errors in each field. If the errors returns after submitting the form, how will you refill the form with the previous data
