[SOLVED] # sign instead of $ when user terminal

zrdc28 · 02-11-2022, 05:13 AM

I just did a clean install of Slackware 15, everything went well except I have 2 problems. when in user mode terminal displays a # sign.
I have searched and tried everything I found on web but to no joy.

My second problem is that I cannot get .bashrc to run when in root
to be able to add colors, aliases etc. I assume that one problem solved will probably correct both. but I have not been able to find that solution.

I found the answer in my own posts from about 18 months ago. getting old is
not always fun!

You can find a lot of .bashrc examples here:

Here's what I use:

Code:

# ~/.bash_profile ######################################################

case $- in
*i* )  # Interactive shell
       if [ -f ~/.bashrc ]; then
          . ~/.bashrc
       fi
       ;;
esac

########################################################################

Code:

# ~/.bashrc ############################################################

[ -r "$ENV" ]  &&  . "$ENV"
[ -r /etc/bashrc ]  &&  . /etc/bashrc


shopt -s checkwinsize          # Keep track of terminal size

# Aliases:

alias less='less -XFRM'

# Bail out if we're not on a full-feature terminal:
if [ "$TERM" == 'dumb' ]; then
  return 0
fi

# ANSI Terminal control sequences to implement text styles,
# for use in prompts (and/or elsewhere):
declare -A style=(
  [default]=$( tput -S <<< $'sgr0\nop' )
  [prompt]=$( tput -S <<< $'sgr0\nop\nbold' )
  [input]=$( tput -S <<< $'sgr0\nop\nbold\nsetaf 5' )
  [warning]=$( tput -S <<< $'sgr0\nop\nbold\nsetaf 3' )
  [error]=$( tput -S <<< $'sgr0\nop\nbold\nsetaf 1' )
)

# Bash prompts:
#   'trap' ensures we clean up after ourselves on exit.
trap "tput -S <<< $'sgr0\nop'" EXIT
PS1=\\[${style[prompt]}\\]\\$\ \\[${style[input]}\\]
PS2=\\[${style[prompt]}\\]\>\ \\[${style[input]}\\]
PS0=${style[default]}

That sounds like you are logging in as root user. Is it safe to assume you have created a non-root user and are logging in with that user? The # symbol indicates a root terminal, usually. Forgive me if this is too obvious and you have already ruled that out.

PS1=$ will display a '$'
PS1=\$ will also display a '$'
PS1=\\$ will display a '$' for non-root and a '#' for root.

And if that \\$ is followed by a word that could be interpreted as a shell variable, you need to do: PS1=\\\$word

Also, whether or not you use single or double quotes or not can confuse matters.

When setting PS1, you need to get the shell-escaping right in order to get the desired result.

you can find good pages on the net regarding PS1, like this: https://bashrcgenerator.com/

For what its worth here is my .bashrc:

Code:

FILES=~/.config/bash/*

for f in $FILES; do
    source $f
done

Code:

$ls ~/.config/bash/

aliases  bashPrompt  colouredMan  dirColors  functions

Code:

$cat bashPrompt

#!/bin/bash

# Test to see what terminal we have and change the prompt accordingly
if [ $TERM == linux ]; then
        if [[ $(id -u) == 0 ]]; then
                export PS1="[\[\e[31m\]\u\[\e[m\]]-[\[\e[32m\]\w\[\e[m\]] \n\[$(tput sgr0)\][\[\e[36m\]\A\[\e[m\]]--> "
        else

The xterm prompt was lifted from the nord color theme, with some changes.

The chances are you do not want to do it the way that I have

You didn't, on the off chance, make your user UID 0 did you? (i.e. that is allowed so you can have multiple root accounts by doing that)

That would cause your prompt to show #
