What does "set|grep PS" return to you? PS1 is likely your ill component. When
you see the actual string it has you can search for that. The string probably
does not look like the default. I think the default is '[\u@\h \W]\$ ' with the
single quotes.
"set|grep PS" Produces more data than I can deal with visually,
roughly two screens full ...
Um, you are using bash. Have you heavily modified your system? This is all
it should produce:
===8<---
GROUPS=()
PS1='[\u@\h \W]\$ '
PS2='> '
PS4='+ '
===8<---
"set" without any "|grep PS" following it is a whole lot of lines of stuff.
But that's not what you did, theoretically.
set|grep PS1
should produce only the "PS1='[\u@\h \W]\$ '" line from the above.
Once you know the errant string you can look for it fairly easily if you
escape the backslashes. And with that in mind, bashrc has this string in it:
[ "$PS1" = "\\s-\\v\\\$ " ] && PS1="[\u@\h \W]\\$ "
So it looks like you can expect to see that bash script under SOME conditions.
And reading that line leads me to suspect I need to look at "man bash". That
tells me this string is the default for a bash shell if nothing else sets the
prompt differently.
Is your /etc/bashrc file still there? And if it is look for the reason it
skips that line. This is the context in my SL6.2 install. The significant
line is the third one up from the bottom of my clipping.

These look identical to me ~
From box6 which works as expected:
[ -e /etc/sysconfig/bash-prompt-default ] &&
PROMPT_COMMAND=/etc/sysconfig/bash-prompt-default
From Box9 with the strange prompt:
[ -e /etc/sysconfig/bash-prompt-default ] &&
PROMPT_COMMAND=/etc/sysconfig/bash-prompt-default
Then somehow while it still declares you are using bash your bash is not
reading /etc/bashrc for some reason. You might check its permissions:
-rw-r--r--. 1 root root 2679 Jun 28 2011 /etc/bashrc
