Work as admin without sudo.

I just wanted to know is it possible or not. I understand that it is possible but a bad idea.

Boom, now as long as you keep the terminal open you are root....Install, delete, modify the system as you wish.

That's sort of a, um, weird/interesting way to do it (IMHO). I usually just issue either "su - root" + password or "sudo /bin/bash" and work as root until I issue exit/^D. I always make sure that root's prompt (PS1) red as a visual reminder that a slip of the keyboard could be disastrous.

I used to do that, too, until a tech at the data center freaked out when I logged in at the console while he was watching

I now set PS1 to blue, and have the background on my remote terminals set to a red-ish (kinda pink) color (just red was pretty rough on the eyes)

Point being: Some additional reminder that one is logged in as root is an excellent idea.

Agreed. A red background would be tough to read for very long. I just set the prompt string itself to red and return to 'normal' once the prompt has been displayed. If you want to limit your time on the system as root, make the prompt blink. :^D

I use a reverse video prompt that ends with a # char (and a space).
Makes the prompt stand out and warns me twice that I'm root now.

Hi,

I just set my prompt to 'red' for root and 'green' for user. One way is through '~/.bashrc' ;

Code:

#.bashrc
#08-30-06 12:20 gws copied loki:/root

# Add bin to path
export PATH="$PATH:$HOME/bin"
#export PATH="$PATH:$HOME:/bin"
# Dynamic resizing
shopt -s checkwinsize
#
#save bash history so as to share

shopt -s histappend
PROMPT_COMMAND='history -a'

# Custom prompt
#PS1='\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

#08-29-06 11:40 gws

if [ `id -un` = root ]; then
   PS1='\[\033[1;31m\]\h:\w\$\[\033[0m\] '
 else
   PS1='\[\033[1;32m\]\h:\w\$\[\033[0m\] '
fi
#
# Add color
eval `dircolors -b`

#Terminus is a very nice Unicode font for the Linux console
#02-02-12 gws
#from dugan's site http://duganchen.ca/writings/slackware/fonts/

#04-30-12 11:41 removed
#
#if [ $TERM = "linux" ]; then
#    setfont ter-v16n
#fi

# User defined aliases
alias cls='clear'
alias clls='clear; ls'
alias ll='ls -l'
alias listlong='ls -l'
alias lsa='ls -A'
alias lsg='ls | grep'
alias lsp='ls -1 /var/log/packages/ > package-list'
alias na='nano'
alias web='links -g -download-dir ~/ www.google.com'

#08-29-06 11:50 gws

#To clean up and cover your tracks once you log off
#Depending on your version of BASH, you might have to use
# the other form of this command
   trap "rm -f ~$LOGNAME/.bash_history" 0

#The older KSH-style form
#   trap 0 rm -f ~$LOGNAME/.bash_history

Very useful!
Hope this helps.
Have fun & enjoy!

Thank you.

Possible yes, but why? It would be similar to having two Presidents, two Pope's, two God's, or the all to often used too many Chiefs and not enough Indians, etc... Better to create proper sudo accounts with strong but restricted abilities.

The "# -> root" and "$ -> normal user" prompt convention has been around for, well, ever. Not everything that's been around for a long time is necessarily bad. :^)
