Bash prompt

[Alex Yarmol]

Hi, dear FreeBSD developers etc. :)

I have a question.

How I can chage my bash prompt to this:

[user at host directory-name(e. g. "alex" for /usr/home/alex)]$

I assume that I need to do that:

export PS1='[\u@\h \(here i don't know what to do, i assume, that I
need to write "\p" or "\P", but it's not working)]\$

I've try to read "man bash", but didn't find what I want :(

Help me please.

Best regards, Alex Yarmol
