bashrc and root

fluxism · 06-16-2009, 05:09 AM

I have a simple couple of alias` set up on my user account.

alias ls='ls -l --color'
alias .='cd ..'
alias ..='cd ../..'

All well and good!

When I su to root, and ls, I get the normal output shown, and not my desired output long-form with colour.

So I should change the roots .bashrc too right? I tried this too my changing /root/.bashrc and the alias` aren't used.

So which file should I be editing to enable my alias commands for root? I could change the /etc/bashrc file(!?) and it would be changed system wide, but this isnt exactly what I am trying to do!

Any ideas?

/root/.bashrc

Indeed, this is what I would of thought too! But is not adding my alias to the ls command, here's my current /root/.bashrc file

Code:

# .bashrc

# User specific aliases and functions

alias ls='ls -l --color'
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

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

I'm running CentOS by the way. ls will just give me the normal output, not the desired one.

Changes should appear but you will need to log out and login back for changes to take effect.

Well that section in mine looks like:

Code:

if [ -x /usr/bin/dircolors ]; then
    eval "`dircolors -b`"
    alias ls='ls --color=auto'
    #alias dir='dir --color=auto'
    #alias vdir='vdir --color=auto'

    #alias grep='grep --color=auto'
    #alias fgrep='fgrep --color=auto'
    #alias egrep='egrep --color=auto'
fi

(Thats /root/.bashrc)

Yep, I tried logging out of root, then back in, and even tried rebooting (windows behavior! ahem). Still no joy though, editing the /root/.bashrc file doesn't add the colour and long form I am after.

Yes You have to do su - as to make this bashrc execute while logging

Hi,

I like to setup properly with a '.bash_profile' and a '.bashrc'.

Quote:

~# cat .bash_profile
# .bash_profile
#08-30-06 12:21

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

Quote:

~# cat .bashrc
#.bashrc

# Add bin to path
export PATH="$PATH:$HOME/bin"

# Dynamic resizing
shopt -s checkwinsize

# 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`

# User defined aliases
alias cls='clear'
alias clls='clear; ls'
alias ll='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'

#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

Yes, once you create the 'bash' files you will have to log out for that user and log back in to have the effects. I would suggest that you add your alias to the above or something along those lines

. My reasoning is that you should have good entry and exit for the 'BASH'. Things will be cleaner!

I like to have a colored prompt to differentiate the root from a normal user since I will be using multiple consoles.
