hwclock should already be handled by /etc/rc.d/rc.S

I'd put any ntpdate stuff in /etc/rc.d/rc.local, myself.

I have no idea why you have the line

Code:

export USER=vl70

in that .bashrc file.

When you say "root .bashrc file", do you mean root's .bashrc file?

Anyway, this is my normal login user's .bashrc:

Code:

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# setup environment for any login
export TEMP=/tmp/${USER}
export TMP=${TEMP}
mkdir -p ${TEMP}

# setup environment for interactive logins
if [ "$PS1" ] ; then
  # source environment settings
  if [ -d ~/etc/env.d ] ; then
    for f in $(find ~/etc/env.d -type f); do
      . $f
    done
  fi
fi

I drop various files with export or function definitions in ~/etc/env.d, like so...

Code:

~$ cat etc/env.d/qemu 
# Qemu can use SDL sound instead of the default OSS
export QEMU_AUDIO_DRV=spice
# Whereas SDL can play through alsa:
#export SDL_AUDIODRIVER=alsa

Works For Me But Maybe Not For Anyone Else (TM).

Hmmm - I guess your 'pwd' is kinda being 'overwritten' ...
Personally, I don't see the need for such a lot of shortcuts, but hey, there's no accounting for taste ...

Mine, more or less (certainly less), goes like this:

Code:

export PS1="\h:\w \$ "
alias lf='ls -Fax'
alias l='ls -al'
alias cp='cp -p'
alias scp='scp -p'
alias md='sudo mkdir -p -m 0777'
alias sshfs='sudo sshfs -o allow_other'
alias grepit='egrep -v "^\s*(#|$)"'
alias burn='sudo cdrecord -v driveropts=burnfree dev=/dev/sr0 -dao -eject -data'
## I have problem with my usb-mouse :-(  (acer aspire one)
alias mouse-reset='sudo rmmod uhci_hcd && sudo modprobe uhci_hcd'

ooops - forgot you asked for root's .bashrc - if you remove the sudo's (and change the PS1), its the same

Richard Cranium · 09-01-2014, 12:58 PM

You can use bash functions pretty much like alias; the one advantage is that a function takes parameters but alias doesn't.

For example, I use the following commands to manage the ssh keys for my users in a libvirt based multi-server lab. All those commands tab-complete in bash (including the ones starting with "_").

Code:

~$ cat etc/env.d/libvirt
# -*- mode: sh -*-
function _lab () {
    ssh lab${1}adm@${2}
}

function _lab1 () {
    _lab ${1} 10.0.0.10
}

function _lab2 () {
    _lab ${1} 10.0.10.10
}

function _lab3 () {
    _lab ${1} 10.0.1.10
}

function _lab4 () {
    _lab ${1} 10.0.11.10
}

function lab1 () {
    _lab1 app
}

function lab2 () {
    _lab2 app
}

function lab3 () {
    _lab3 app
}

function lab4 () {
    _lab4 app
}

function syslab1 () {
    _lab1 sys
}

function syslab2 () {
    _lab2 sys
}

function syslab3 () {
    _lab3 sys
}

function syslab4 () {
    _lab4 sys
}

function dblab1 () {
    _lab1 db
}

function dblab2 () {
    _lab2 db
}

function dblab3 () {
    _lab3 db
}

function dblab4 () {
    _lab4 db
}

function appb2labs () {
    scp ${1} labappadm@10.0.0.10:/var/app/extract
    scp ${1} labappadm@10.0.10.10:/var/app/extract
}

function load2lab1 () {
    scp ${1} labappadm@10.0.0.10:/var/app/loads
}

function load2lab2 () {
    scp ${1} labappadm@10.0.10.10:/var/app/loads
}

function load2lab () {
    load2lab1 ${1}
    load2lab2 ${1}
}

function _rekey () {
    for i in "labappadm" "labsysadm" "labdbadm"; do
        for j in $*; do
            ssh-copy-id ${i}@${j}
        done
    done
}


function rekey2 () {
    _rekey 10.0.10.10 10.0.11.10
}

function rekey1 () {
    _rekey 10.0.0.10 10.0.1.10
}

function _unkey () {
    for j in $*; do 
        ssh-keygen -R ${j}
    done
}

function unkey1 () {
    _unkey 10.0.0.10 10.0.1.10
}

function unkey2 () {
    _unkey 10.0.10.10 10.0.11.10
}

I haven't bothered creating an /etc/bashrc, but here's my ~/.bashrc:

Code:

[ -z "$PS1" ] && return
export HISTFILE="$HOME/.bash_history"    
export HISTSIZE=${HISTSIZE:-"1000"}      
export HISTFILESIZE=${HISTSIZE:-"2000"}  
export HISTCONTROL=ignoredups
shopt -s checkwinsize
shopt -s histappend

}
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
alias du='du -h'
alias df='df -h'

And my ~/.bash_profile:

Mine is very simple. I edited the prompt to remind me that I am su-ed to root.

Code:

PS1="\[\033[1;31m\]\u\[\033[0m\]:\w/ $ "

schmatzler · 09-02-2014, 10:39 AM

Code:

export PS1="\[\e[00;33m\]\u\[\e[0m\]\[\e[00;37m\]@\[\e[0m\]\[\e[00;36m\][\w]:\[\e[0m\]\[\e[00;37m\] \[\e[0m\]"

Looks like this:

Hi,

I like to keep my root & user by;

Code:

# 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\$\[\033[0m\] '  # as buck1:~# 
else PS1='\[\033[1;32m\]\h:\w\$\[\033[0m\] '                                 # as buck1:~$ 
fi  #

I 'KISS' therefore easier to note root & normal user unique via color signification of # & $.

Hmmm - I guess your 'pwd' is kinda being 'overwritten' ...

Also his pkgtool since there's another alias for p further down for ps aux.

Anyway, all I really do is remove the root checks for setting the $PATH variable to include all the root locations too (so all users get the same $PATH root would). I compromise my security by setting up sudo with no passwords and all commands for my user (I did this long before Ubuntu came to be so it had nothing to do with their weird implementation of sudo, and I've taken into account the security implications and decided I'd rather go for simplicity than security), and I don't like typing full paths. Plus, you can't ssh in to my network from the internet and I'm the only person who uses a linux CLI on the network, so I'm not too worried about someone getting in and screwing things up.

astrogeek · 09-02-2014, 03:16 PM

As already noted by others, in my root .bashrc I always color the prompt red - red prompt=root on any machine.

This thread is specifically about the root .bashrc, and we all know that nobody would allow root login via SSH...

But in my non-root .bashrc's (/etc/skel/.bashrc) I detect remote logins and color the prompt so that if I see a colored prompt I always know I am remote.

Code:

#Make prompt colored when logged in remote
export NON_LOCAL_LOGIN=`env | grep SSH`
if [ "$NON_LOCAL_LOGIN" != "" ]; then
       PS1="\033[33m[\u@\h:\w]#\033[0m "
fi;

I spend most of my days in Tmux'd sessions, often with more than 20 windows open, many of those in remote sessions, so this has been a very important "feature" for me.

I have used different colors for different machines at times for better recognition, but colored prompt=remote in any context.

frankbell · 09-02-2014, 08:52 PM

schmatzler, looks like this on my system:

Code:

root:/home/[username]/ $

It serves its purpose.

But for me it's very confusing as a root prompt should end with a '#' not a '$'. I reckon your PS1 variable should be:

Code:

PS1="\[\033[1;31m\]\u\[\033[0m\]:\w/ \\$ "

pan64 · 09-03-2014, 05:40 AM

Hm. I set different background for root, there is nothing special in .bashrc. Actually I think root's shell should not contain any fancy coloring, aliases or prompt just direct and fast access to the bare system.
