I'm using ghci 6.8.2 on Ubuntu. Does ghci use a configuration file where we can do some initial setup?. E.g.: :set prompt "ghci> ".

Have you tried adding :set prompt "ghci> " to ~/.ghci?

Sorry for such a basic question, but I can't understand: What is the full name of the .ghci file? And where exactly to put that file? I tried putting this file in the neighbourhood of a haskell code file, but the ghci didn't seem to read that .ghci file. – awllower Feb 26 '15 at 5:14
    
In Windows, you put the file in your user directory. E.g. `C:\Users\YourUsername`. – MasterMastic Apr 2 '15 at 8:09

Having applied @hvr's answer I got the following warning:

*** WARNING: ~/.ghci is writable by someone else, IGNORING!

The solution is chmod g-w ~/.ghci.
