wierd newline functionality

[shira]

I dunno when it started but one of my servers is acting kinda funky

at the end of every prompt does an extra newline like so:

serverbox / # [*I just hit enter*]

serverbox / #

or

serverbox / # ls
bin c etc lib opt root stage2-athlon-xp-20030910.tar.bz2 tmp var
boot dev home mnt proc sbin sys usr

serverbox / #

the cursor is always red too

it's not a big issue but it is rather annoying
is anyone else having/had this problem?

What does 'echo $PS1' show?

[shira]

serverbox / # echo $PS1
\[\033[01;31m\]\h \[\033[01;34m\]\W \$ \[\033[00m\]


it does some even wierder stuff with regular user prompts too:
serverbox / $ echo hello
hello
shira@
serverbox / $

PS1 for that is: \[\033[01;32m\]\u@\h \[\033[01;34m\]\W \$ \[\033[00m\]

There is a feature called PROMPT_COMMAND as well.

Here a program can be set to run each time the prompt string is displayed.

What might be happening is it is set to display a new line then display prompt string.

So you actually get :
----------------------------------
#This line is blank but belongs to the prompt below
serverbox / # echo Hello
Hello
# This line is blank but not generated from above, but rather from below
serverbox / #

Check your .bashrc and your /etc/profile, for PROMPT_COMMAND being set. If it is, wonder very hard how that happened.

If the above does not apply, how are you accessing the box? and what has recently changed on the box?

Some time ago I had trouble with \[\033... escape sequences. I use these instead and it solved all of my problems:
