Bash is broken Topic is solved

[dedanna1029]

Not sure how to get this straightened out.

I noticed after I mounted my /home folder in CentOS 6.2 (post-install), that all I was getting was the bash 4.1 prompt. So, I checked out ~/. and there was no .bashrc or .bash_profile, so I created them via here. After I did, there were "anomalies", such as no prompt at all for plain su, yet a prompt for su -. Also when using just plain su, there was a /home/dedanna/bin: path added when I would echo $PATH, but not when I'd su - (note the difference; the dash). I can no longer log into root now, at all, not with terminal, not with anything, and after a reboot, I'm back to the bash 4.1 prompt, because I reset the files in ~/, thinking they're screwed.

I tried various fixes in the files, they wouldn't fly no matter what I did. Can someone please check these out and see what I have to do for these? Maybe the paths are wrong? Here's what I had in each:

In my /home, I edited them to this:

Code: Select all

# .bashrc

# User specific aliases and functions

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

    smiley() {
        if [ $1 == 0 ] ; then
    echo ":)"
        else
    echo ":)"
           fi
        }
    smileyc() {
        if [ $1 == 0 ] ; then
    echo $GREEN
    else
    echo $RED
           fi
        }
    if [ $(tput colors) -gt 0 ] ; then
    RED=$(tput setaf 1)
    GREEN=$(tput setaf 2)
    RST=$(tput op)

            # Sometimes COLUMNS isn't initiliased, if it isn't, fall back on 80
            [ $maxpwdlen -lt 0 ] && maxpwdlen=$(( 80 - ps_len ))

                    startpos=$(( $pwdlen - maxpwdlen + ${#overflow_prefix} ))

            fi
            export PS1="${PS1_T1}${PROMPT_PWD}${PS1_T2}"
    smiley=$(smiley $RTN)
    smileyc=$(smileyc $RTN)
            local CY="\[\e[1;31m\]" # Each is 12 chars long

            export PS1="${PS1_T1}${PROMPT_PWD}${PS1_T2}"
    }
    PROMPT_COMMAND=bash_prompt_cmd


Code: Select all

# .bash_profile

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

# User specific environment and startup programs

PATH=$PATH:$HOME/bin:.
BASH_ENV=$HOME/.bashrc
USERNAME="dedanna"

export USERNAME BASH_ENV PATH

I did the same for root's, except changed the username line to dedanna for my /home, left it as root for root's. This is all very strange to me. I've edited both before, with no problem.

Here's a kicker for you, not sure if it has anything to do with it. I had to, post-install, chown my /home folder to me, because of this error. I don't know if that has anything to do with this, but with it being a permissions thing, I'm figuring it might have. I used:

Code: Select all

chown -R dedanna:dedanna /home/dedanna

Not being able to get into root right now from terminal or anywhere else at all is ending up to be a royal pain - I can't install anything, I can't do anything I need to. This also puts me in a vicious cycle wherein I can't reset those two files in root. When I try logging into root, it hangs for a minute or two, then goes right back to regular user. This is from Ctl+Alt+F2, from terminal in the desktop, and when I try logging in directly from gdm.

Thanks.

Relatively big question there so here is a start

Code: Select all

[berserk@centos ~]$ cat .bashrc
# .bashrc

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

# User specific aliases and functions


That is what it looks like if you do not play with it....

That, I didn't play with, until I saw an example of it, changed to that. Remember, it wasn't even there in /home until I created it. I'll change it to what you have there, and then we'll go from there. Thanks.

Now, the problem lies, how do I get into root to check out its .bashrc?

Thanks.

Edit: Never mind, am in via the livedvd.

Edit2: That did it. It was root's .bashrc - I'd missed a line.

Thank you. Just needed a pointer on where to look.
