Users' bash prompt not as expected (Mandriva 2006)


I'm having some problems with a Mandriva 2006 machine. User prompts are appearing as "Bash-3.00~$" instead of "whomever@wherever /home/whomever$". There are also no dir_colors for users.

I've had a look at /etc/bashrc (see below) but my bash scripting isn't great. I can see where the erroneous prompt is coming from ([ "$PS1" = "\\s-\\v\\\$ " ] && PS1="[\u@\h \W]\\$ ") but I don't understand what the bashrc authors were trying to accomplish here. Before I simply replace the offending line with "[ "$PS1" = "[\u@\h \W]\\$ " ]" I'd welcome comments both on this "solution" and on the intentions of the authors.

Code:
# /etc/bashrc

# System wide functions and aliases
# Environment stuff goes in /etc/profile

# by default, we want this to get set.
# Even for non-interactive, non-login shells.
if [ "`id -gn`" = "`id -un`" -a `id -u` -gt 99 ]; then
        umask 002
else
        umask 022
fi

# are we an interactive shell?
if [ "$PS1" ]; then
    case $TERM in
        xterm*)
            PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD}\007"'
            ;;
        *)
            ;;
    esac
    [ "$PS1" = "\\s-\\v\\\$ " ] && PS1="[\u@\h \W]\\$ "

    if [ -z "$loginsh" ]; then # We're not a login shell
        for i in /etc/profile.d/*.sh; do
            if [ -x $i ]; then
                . $i
            fi
        done
    fi
fi

unset loginsh

what does your ~/.bashrc says?

If it just happened (as in yesterday was 0k) it might have beeen a permissi0n pr0blem. Usually when it can't see y0ur h0me and it happens when the kernel m0dules are n0t l0aded s0 it can't m0unt y0ur /h0me partiti0n.

Good guess but in Mandriva there is no ~/.bashrc file (except for root), so the unwelcome prompt is definitely coming from the file I posted above.

I have the following .bashrc in my normal user account on Mandriva 2006
Code:
# .bashrc

# User specific aliases and functions

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi


# This line was appended by KDE
# Make sure our customised gtkrc file is loaded.
export GTK2_RC_FILES=$HOME/.gtkrc-2.0

Hmm. You're right. I've also had a look at another Mandriva 2006 system, and its users have .bashrc, .bash_profile and .bash_logout files. I wonder why they didn't appear on the system I was working on. In any event, I'm going to post the contents of all three files (as I found them in /etc/skel on a recent Mandriva 2006 install) in case anyone else has this problem and needs them:

.bashrc
Code:
# .bashrc

# User specific aliases and functions

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi
.bash_logout
Code:
# ~/.bash_logout

clear
.bash_profile
Code:
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH
unset USERNAME
There was also .screenrc
Code:
#
# Example of a user's .screenrc file
#

# This is how one can set a reattach password:
# password ODSJQf.4IJN7E    # "1234"

# no annoying audible bell, please
vbell on

# detach on hangup
autodetach on

# don't display the copyright page
startup_message off

# emulate .logout message
pow_detach_msg "Screen session of \$LOGNAME \$:cr:\$:nl:ended."

# advertise hardstatus support to $TERMCAP
# termcapinfo  * '' 'hs:ts=\E_:fs=\E\\:ds=\E_\E\\'

# make the shell in every window a login shell
#shell -$SHELL

# autoaka testing
# shellaka '> |tcsh'
# shellaka '$ |sh'

# set every new windows hardstatus line to somenthing descriptive
# defhstatus "screen: ^En (^Et)"

defscrollback 1000

# don't kill window after the process died
# zombie "^["

# enable support for the "alternate screen" capability in all windows
