[solved][bash] PS1 wrapping problem...

pyther · 2008-10-13 23:45:29

Hello I have my ps1 set to

# Prompt
BGREEN='\[\033[1;32m\]'
GREEN='\[\033[0;32m\]'
BRED='\[\033[1;31m\]'
RED='\[\033[0;31m\]'
BBLUE='\[\033[1;34m\]'
BLUE='\[\033[0;34m\]'
NORMAL='\[\033[00m\]'

if [ "$TERM" = "linux" ]; then
    PS1="${NORMAL}[\u${BLUE}@\h ${BGREEN}\W${NORMAL}]\$ "
else
    PS1="\e]2;\u@\H:\w\a${NORMAL}[\u${BLUE}@\h ${BGREEN}\W${NORMAL}]$ "
fi

However when my prompt displays [pyther@tux world.pyther.net]$ (color) I can only type 3 characters and then it wraps. Please see the screenshot...

Using a regular prompt (source /etc/profile) works like a charm. Any help would be great!

Try escaping the last $ in your else..fi block.

PS1="\e]2;\u@\H:\w\a${NORMAL}[\u${BLUE}@\h ${BGREEN}\W${NORMAL}]\$ "

As so? It gives me 5 characters, a slight improvment!

Didn't I just answer this question in another thread? You need to escape the colors codes with \[ \] so that bash knows that they are non-printing characters, otherwise they will be counted in the prompt length.

I am not sure what you mean, don't I have that?

NORMAL='\[\033[00m\]'

Try changing the single quotes to double quotes in your color variable assignments.

# Prompt
PS1="[\u\[\033[0;34m\]@\h \[\033[1;32m\]\W\[\033[00m\]]\$ "

# X Terminal titles
case "$TERM" in
xterm*|rxvt*)
        PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD}\007"'
        ;;
*)
        ;;
esac

The ps1 prompt I just put the color codes in. o_0

I found the second part in this thread and it worked wonders! http://bbs.archlinux.org/viewtopic.php?id=48358

Thanks for your help!

You're probably confusing this thread with mine a few days ago about using colors in PS1 in bash. ( http://bbs.archlinux.org/viewtopic.php? … 03#p432903 )

This issue is very similar indeed
