[SOLVED] Display-bash-4.2#, not changing to my username

san2ban · 06-15-2013, 12:41 AM

Dear Slackers
First, my bash was displayed as bash-4.2$, bash-4.2# for user and root.
I edited the file 'profile', by un commenting the one for above

Code:

bash-4.2# cat /etc/profile
# /etc/profile: This file contains system-wide defaults used by
# all Bourne (and related) shells.

# Set the values for some environment variables:
export MINICOM="-c on"
export MANPATH=/usr/local/man:/usr/man
export HOSTNAME="`cat /etc/HOSTNAME`"
export LESSOPEN="|lesspipe.sh %s"
export LESS="-M"

# If the user doesn't have a .inputrc, use the one in /etc.
if [ ! -r "$HOME/.inputrc" ]; then
  export INPUTRC=/etc/inputrc
fi

# Set the default system $PATH:
PATH="/usr/local/bin:/usr/bin:/bin:/usr/games"

# For root users, ensure that /usr/local/sbin, /usr/sbin, and /sbin are in
# the $PATH.  Some means of connection don't add these by default (sshd comes
# to mind).
if [ "`id -u`" = "0" ]; then
  echo $PATH | grep /usr/local/sbin 1> /dev/null 2> /dev/null
  if [ ! $? = 0 ]; then
    PATH=/usr/local/sbin:/usr/sbin:/sbin:$PATH
  fi
fi

# I had problems with the backspace key using 'eval tset' instead of 'TERM=',
# but you might want to try it anyway instead of the section below it.  I
# think with the right /etc/termcap it would work.
# eval `tset -sQ "$TERM"`

# Set TERM to linux for unknown type or unset variable:
if [ "$TERM" = "" -o "$TERM" = "unknown" ]; then
 TERM=linux
fi

# Set ksh93 visual editing mode:
if [ "$SHELL" = "/bin/ksh" ]; then
  VISUAL=emacs
#  VISUAL=gmacs
#  VISUAL=vi
fi

# Set a default shell prompt:
PS1='`hostname`:`pwd`# '
if [ "$SHELL" = "/bin/pdksh" ]; then
 PS1='! $ '
elif [ "$SHELL" = "/bin/ksh" ]; then
 PS1='! ${PWD/#$HOME/~}$ '
elif [ "$SHELL" = "/bin/zsh" ]; then
 PS1='%n@%m:%~%# '
elif [ "$SHELL" = "/bin/ash" ]; then
 PS1='$ '
else
 PS1='\u@\h:\w\$ '
fi
PS2='> '
export PATH DISPLAY LESS TERM PS1 PS2

# Append any additional sh scripts found in /etc/profile.d/:

done
unset profile_script

fi

bash-4.2#

I created a .bashrc file as below

Code:

san2ban@KRISHNA:~$cat .bashrc
PS1="\u@\h:\w$"
PS2="\u@\h:\w#"
san2ban@KRISHNA:~$

Now, for user, I am happy with the display. For root, still bash-4.2 is displayed.
Pl. indicate, what is to be edited

TobiSGD · 06-15-2013, 01:05 AM

Copy the ~/.bashrc file to /root and it should work.

kabamaru · 06-15-2013, 04:07 AM

I don't know if your PS2 setting is on purpose, but FYI PS2 is the secondary prompt i.e. what your prompt will look like when you break your command in two or more lines. It is not your root's primary prompt.

As for PS1, replace "\u@\h:\w$" with "\u@\h:\w\$" (or better "\u@\h:\w\$ ") for both regular user and root, and do as TobiSGD suggested. "\$" means "$" for regular user, and "#" for root.

san2ban · 06-15-2013, 04:12 AM

TobiSGD
Did as you suggested
Does not work

Code:

bash-4.2# cat .bashrc
PS1="\u@\h:\w$"
PS2="\u@\h:\w#"
bash-4.2#

ponce · 06-15-2013, 04:18 AM

~/.bashrc is not read for login shells: if you want it to be used also for those you gotta create a ~/.bash_profile (both for your user and root) with this content

Code:

# ~/.bash_profile: executed by bash(1) for login shells.

# include .bashrc if it exists
if [ -f ~/.bashrc ]; then
  source ~/.bashrc
fi

astrogeek · 06-15-2013, 04:18 AM

Actually, I think your ~/.bashrc is not being read.

When you login bash only reads ~/.bash_profile

If you want to read ~.bashrc you need to create a ~/.bash_profile with something like this...

Code:

if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

[EDIT]
ponce beat me by 17ms... at least!

Did as you suggested. Removed PS2. Still, for root, no change

Code:

bash-4.2# cat .bashrc
PS1="\u@\h:\w\$"

bash-4.2#

kabamaru · 06-15-2013, 04:26 AM

@ponce,astrogeek: if he didn't modify his /etc/profile, his login shells should be fine though.

san2ban · 06-15-2013, 04:27 AM

Ponce, Astrogeek
Still same display

Code:

bash-4.2# cat .bash_profile
# ~/.bash_profile: executed by bash(1) for login shells.

# include .bashrc if it exists
if [ -f ~/.bashrc ]; then
  source ~/.bashrc
fi
bash-4.2#

have you logout and logged in again?
how do you become root? use "su -"

try also to add an export to the PS1 line in .bashrc, so you will have it also in child shells, like

Code:

export PS1="\u@\h:\w\$"

and, like kabamaru says, use the standard /etc/profile: you can add your customizations to ~/.bash_profile

san2ban · 06-15-2013, 04:39 AM

Using standard /etc/profile. added 'export' as you suggested. Still same display.
Yes, I use 'su' for becoming root

Code:

bash-4.2# cat .bashrc
export PS1="\u@\h:\w\$"

bash-4.2#

bash init file are read when it's executed, so you have to logout and re-login (or launch a new shell with the command "bash")

note that I've written "su -" (with an additional space and a -), not just "su".

Logging out and in did not help. I rebooted the system, and now it works. Thanks to all for your time and suggestions. SLACKWARE14-64bit ROCKS!!!

Code:

san2ban@KRISHNA:~$su
Password: 
root@KRISHNA:/home/san2ban$

Further suggestions, if any, are accepted gratefully, gracefully

champalal · 02-21-2019, 01:59 AM

Check the .bashrc file in the "/" (root) if there is below contains.

# .bashrc

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

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

then create the duplicate of the .bashrc file and rename with the .bash_profile or you can copy the above contains and create the .bash_profile new file and paste the same. and change the permission of file (.bash_profile) as 777 and it will resolve your issue.
