Poetry Shell: How to shorten bash prefix


When activating a poetry python shell, I get a very long string in my bash prompt:

(my-current-folder-pNzYm0GW-py3.8) (base) myusername@mycomputername>

I'd like to have it much shorter, maybe like this:

(py3.8) myusername@mycomputername>

Does anyone know how to do that?

(I guess the base comes from miniconda being also installed on the system, which I can probably fix by editing my .bashrc)


Solution

  • You can change the value of your interactive prompt :

    export PS1="[\u@\h:\w ] $ "

    Where:

    \a : an ASCII bell character (07)
    \d : the date in “Weekday Month Date” format (e.g., “Tue May 26”)
    \D{format} : the format is passed to strftime(3) and the result is inserted into the prompt string; an empty format results in a locale-specific time representation. The braces are required
    \e : an ASCII escape character (033)
    \h : the hostname up to the first ‘.’
    \H : the hostname
    \j : the number of jobs currently managed by the shell
    \l : the basename of the shell’s terminal device name
    \n : newline
    \r : carriage return
    \s : the name of the shell, the basename of $0 (the portion following the final slash)
    \t : the current time in 24-hour HH:MM:SS format
    \T : the current time in 12-hour HH:MM:SS format
    \@ : the current time in 12-hour am/pm format
    \A : the current time in 24-hour HH:MM format
    \u : the username of the current user
    \v : the version of bash (e.g., 2.00)
    \V : the release of bash, version + patch level (e.g., 2.00.0)
    \w : the current working directory, with $HOME abbreviated with a tilde
    \W : the basename of the current working directory, with $HOME abbreviated with a tilde
    \! : the history number of this command
    

    Afterwards just add it to your ~/.bashrc
