Shell Programming and Scripting

Greetz all,
I'm using OBSD 2.9 with /bin/sh as my shell. I want to modify the SH prompt to reflect my current working directory.
I'm new to shell programming, so pardon if I'm going about things wrong
I thought I'd be able to do it with the following line:

Code:

PS1="`pwd`# "

but of course, that leaves the prompt as my home directory when I log in and remains so even when I change directories. Can someone point me to the right way to have my SH prompt update the CWD everytime I CD into a new one?

sorry for the quirkiness, but I should revise this question.

How does one set the prompt to read as follows?

<username>@<hostname>:<current_working_directory>#

for instance,

Code:

user@host:/user$

I would also allow the shell to show a hash (#) when root is logged in and a $ when a regular user logs in.

I thought I had it figured out before, but I didn't.

Hi,

Hope this would help you.



Try to set the PS1 in ~/.shrc or you can type it (not automatic).

-----------------------

PS1=$'\\u@\\h:\\w\\$ '

-----------------------

should be working, and it will show you (for example):

-----------------------

sh-2.05# PS1=$'\\u@\\h:\\w\\$ '

root@negative:~# cd data

root@negative:~/data#

-----------------------

no go.
when I enter that in (actually in my .profile file in ~), the prompt comes out reading:

\u@\h:\w$

not correct, of course.

What I have entered in the variable as follows:

PS1='\\u@\\h:\\w:$ '
export PS1

and also exacltly as you had shown in your reply.
Is it possible it's a different systax for Bourne used under OpenBSD?

Im using OpenBSD and i put a "nice" Prompt:
----
PS1='\[\e[1;30m\][\[\e[0;35m\]\t\[\e[1;30m\]]\[\e[1;36m\]\u\[\e[1;30m\]@\[\e[0;36m\]\h\[\e[1;30m\]:\[\e[0;37m\]\w\[\e[1;30m\]\$\[\e[0;37m\] '
----

just for not getting bored with BLACK & WHITE prompt :)

eh.. I have to ask, which shell are you using? I am using /bin/sh and even copying the variable as you set it ( PS1='\[\e[1;30m\][\[\e[0;35m\]\t\[\e[1;30m\]]\[\e[1;36m\]\u\[\e[1;30m\]@\[\e[0;36m\]\h\[\e[1;30m\]:\[\e[0;37m\]\w\[\e[1;30m\]\$\[0;37m\]' )
only makes my command... exactly that.
can someone refer a tutorial that goes over this?

I'm using /bin/bash, but i believe it works in /bin/sh too,
